Primitive types - * must be passed using wrapper types. The formatting - * is controlled by a control string. - *<p> - * A control string is a Java string that contains a - * control specification. The control specification - * starts at the first percent sign (%) in the string, - * provided that this percent sign - *<ol> - *<li>is not escaped protected by a matching % or is - * not an escape % character, - *<li>is not at the end of the format string, and - *<li>precedes a sequence of characters that parses as - * a valid control specification. - *</ol> - *</p><p> - * A control specification usually takes the form: - *<pre> % ['-+ #0]* [0..9]* { . [0..9]* }+ - * { [hlL] }+ [idfgGoxXeEcs] - *</pre> - * There are variants of this basic form that are - * discussed below.</p> - *<p> - * The format is composed of zero or more directives - * defined as follows: - *<ul> - *<li>ordinary characters, which are simply copied to - * the output stream; - *<li>escape sequences, which represent non-graphic - * characters; and - *<li>conversion specifications, each of which - * results in the fetching of zero or more arguments. - *</ul></p> - *<p> - * The results are undefined if there are insufficient - * arguments for the format. Usually an unchecked - * exception will be thrown. If the format is - * exhausted while arguments remain, the excess - * arguments are evaluated but are otherwise ignored. - * In format strings containing the % form of - * conversion specifications, each argument in the - * argument list is used exactly once.</p> - * <p> - * Conversions can be applied to the <code>n</code>th - * argument after the format in the argument list, - * rather than to the next unused argument. In this - * case, the conversion characer % is replaced by the - * sequence %<code>n</code>$, where <code>n</code> is - * a decimal integer giving the position of the - * argument in the argument list.</p> - * <p> - * In format strings containing the %<code>n</code>$ - * form of conversion specifications, each argument - * in the argument list is used exactly once.</p> - * - *<h4>Escape Sequences</h4> - *<p> - * The following table lists escape sequences and - * associated actions on display devices capable of - * the action. - *<table> - *<tr><th align=left>Sequence</th> - * <th align=left>Name</th> - * <th align=left>Description</th></tr> - *<tr><td>\\</td><td>backlash</td><td>None. - *</td></tr> - *<tr><td>\a</td><td>alert</td><td>Attempts to alert - * the user through audible or visible - * notification. - *</td></tr> - *<tr><td>\b</td><td>backspace</td><td>Moves the - * printing position to one column before - * the current position, unless the - * current position is the start of a line. - *</td></tr> - *<tr><td>\f</td><td>form-feed</td><td>Moves the - * printing position to the initial - * printing position of the next logical - * page. - *</td></tr> - *<tr><td>\n</td><td>newline</td><td>Moves the - * printing position to the start of the - * next line. - *</td></tr> - *<tr><td>\r</td><td>carriage-return</td><td>Moves - * the printing position to the start of - * the current line. - *</td></tr> - *<tr><td>\t</td><td>tab</td><td>Moves the printing - * position to the next implementation- - * defined horizontal tab position. - *</td></tr> - *<tr><td>\v</td><td>vertical-tab</td><td>Moves the - * printing position to the start of the - * next implementation-defined vertical - * tab position. - *</td></tr> - *</table></p> - *<h4>Conversion Specifications</h4> - *<p> - * Each conversion specification is introduced by - * the percent sign character (%). After the character - * %, the following appear in sequence:</p> - *<p> - * Zero or more flags (in any order), which modify the - * meaning of the conversion specification.</p> - *<p> - * An optional minimum field width. If the converted - * value has fewer characters than the field width, it - * will be padded with spaces by default on the left; - * t will be padded on the right, if the left- - * adjustment flag (-), described below, is given to - * the field width. The field width takes the form - * of a decimal integer. If the conversion character - * is s, the field width is the the minimum number of - * characters to be printed.</p> - *<p> - * An optional precision that gives the minumum number - * of digits to appear for the d, i, o, x or X - * conversions (the field is padded with leading - * zeros); the number of digits to appear after the - * radix character for the e, E, and f conversions, - * the maximum number of significant digits for the g - * and G conversions; or the maximum number of - * characters to be written from a string is s and S - * conversions. The precision takes the form of an - * optional decimal digit string, where a null digit - * string is treated as 0. If a precision appears - * with a c conversion character the precision is - * ignored. - * </p> - *<p> - * An optional h specifies that a following d, i, o, - * x, or X conversion character applies to a type - * short argument (the argument will be promoted - * according to the integral promotions and its value - * converted to type short before printing).</p> - *<p> - * An optional l (ell) specifies that a following - * d, i, o, x, or X conversion character applies to a - * type long argument.</p> - *<p> - * A field width or precision may be indicated by an - * asterisk (*) instead of a digit string. In this - * case, an integer argument supplised the field width - * precision. The argument that is actually converted - * is not fetched until the conversion letter is seen, - * so the the arguments specifying field width or - * precision must appear before the argument (if any) - * to be converted. If the precision argument is - * negative, it will be changed to zero. A negative - * field width argument is taken as a - flag, followed - * by a positive field width.</p> - * <p> - * In format strings containing the %<code>n</code>$ - * form of a conversion specification, a field width - * or precision may be indicated by the sequence - * *<code>m</code>$, where m is a decimal integer - * giving the position in the argument list (after the - * format argument) of an integer argument containing - * the field width or precision.</p> - * <p> - * The format can contain either numbered argument - * specifications (that is, %<code>n</code>$ and - * *<code>m</code>$), or unnumbered argument - * specifications (that is % and *), but normally not - * both. The only exception to this is that %% can - * be mixed with the %<code>n</code>$ form. The - * results of mixing numbered and unnumbered argument - * specifications in a format string are undefined.</p> - * - *<h4>Flag Characters</h4> - *<p> - * The flags and their meanings are:</p> - *<dl> - * <dt>'<dd> integer portion of the result of a - * decimal conversion (%i, %d, %f, %g, or %G) will - * be formatted with thousands' grouping - * characters. For other conversions the flag - * is ignored. The non-monetary grouping - * character is used. - * <dt>-<dd> result of the conversion is left-justified - * within the field. (It will be right-justified - * if this flag is not specified).</td></tr> - * <dt>+<dd> result of a signed conversion always - * begins with a sign (+ or -). (It will begin - * with a sign only when a negative value is - * converted if this flag is not specified.) - * <dt><space><dd> If the first character of a - * signed conversion is not a sign, a space - * character will be placed before the result. - * This means that if the space character and + - * flags both appear, the space flag will be - * ignored. - * <dt>#<dd> value is to be converted to an alternative - * form. For c, d, i, and s conversions, the flag - * has no effect. For o conversion, it increases - * the precision to force the first digit of the - * result to be a zero. For x or X conversion, a - * non-zero result has 0x or 0X prefixed to it, - * respectively. For e, E, f, g, and G - * conversions, the result always contains a radix - * character, even if no digits follow the radix - * character (normally, a decimal point appears in - * the result of these conversions only if a digit - * follows it). For g and G conversions, trailing - * zeros will not be removed from the result as - * they normally are. - * <dt>0<dd> d, i, o, x, X, e, E, f, g, and G - * conversions, leading zeros (following any - * indication of sign or base) are used to pad to - * the field width; no space padding is - * performed. If the 0 and - flags both appear, - * the 0 flag is ignored. For d, i, o, x, and X - * conversions, if a precision is specified, the - * 0 flag will be ignored. For c conversions, - * the flag is ignored. - *</dl> - * - *<h4>Conversion Characters</h4> - *<p> - * Each conversion character results in fetching zero - * or more arguments. The results are undefined if - * there are insufficient arguments for the format. - * Usually, an unchecked exception will be thrown. - * If the format is exhausted while arguments remain, - * the excess arguments are ignored.</p> - * - *<p> - * The conversion characters and their meanings are: - *</p> - *<dl> - * <dt>d,i<dd>The int argument is converted to a - * signed decimal in the style [-]dddd. The - * precision specifies the minimum number of - * digits to appear; if the value being - * converted can be represented in fewer - * digits, it will be expanded with leading - * zeros. The default precision is 1. The - * result of converting 0 with an explicit - * precision of 0 is no characters. - * <dt>o<dd> The int argument is converted to unsigned - * octal format in the style ddddd. The - * precision specifies the minimum number of - * digits to appear; if the value being - * converted can be represented in fewer - * digits, it will be expanded with leading - * zeros. The default precision is 1. The - * result of converting 0 with an explicit - * precision of 0 is no characters. - * <dt>x<dd> The int argument is converted to unsigned - * hexadecimal format in the style dddd; the - * letters abcdef are used. The precision - * specifies the minimum numberof digits to - * appear; if the value being converted can be - * represented in fewer digits, it will be - * expanded with leading zeros. The default - * precision is 1. The result of converting 0 - * with an explicit precision of 0 is no - * characters. - * <dt>X<dd> Behaves the same as the x conversion - * character except that letters ABCDEF are - * used instead of abcdef. - * <dt>f<dd> The floating point number argument is - * written in decimal notation in the style - * [-]ddd.ddd, where the number of digits after - * the radix character (shown here as a decimal - * point) is equal to the precision - * specification. A Locale is used to determine - * the radix character to use in this format. - * If the precision is omitted from the - * argument, six digits are written after the - * radix character; if the precision is - * explicitly 0 and the # flag is not specified, - * no radix character appears. If a radix - * character appears, at least 1 digit appears - * before it. The value is rounded to the - * appropriate number of digits. - * <dt>e,E<dd>The floating point number argument is - * written in the style [-]d.ddde{+-}dd - * (the symbols {+-} indicate either a plus or - * minus sign), where there is one digit before - * the radix character (shown here as a decimal - * point) and the number of digits after it is - * equal to the precision. A Locale is used to - * determine the radix character to use in this - * format. When the precision is missing, six - * digits are written after the radix character; - * if the precision is 0 and the # flag is not - * specified, no radix character appears. The - * E conversion will produce a number with E - * instead of e introducing the exponent. The - * exponent always contains at least two digits. - * However, if the value to be written requires - * an exponent greater than two digits, - * additional exponent digits are written as - * necessary. The value is rounded to the - * appropriate number of digits. - * <dt>g,G<dd>The floating point number argument is - * written in style f or e (or in sytle E in the - * case of a G conversion character), with the - * precision specifying the number of - * significant digits. If the precision is - * zero, it is taken as one. The style used - * depends on the value converted: style e - * (or E) will be used only if the exponent - * resulting from the conversion is less than - * -4 or greater than or equal to the precision. - * Trailing zeros are removed from the result. - * A radix character appears only if it is - * followed by a digit. - * <dt>c,C<dd>The integer argument is converted to a - * char and the result is written. - * - * <dt>s,S<dd>The argument is taken to be a string and - * bytes from the string are written until the - * end of the string or the number of bytes - * indicated by the precision specification of - * the argument is reached. If the precision - * is omitted from the argument, it is taken to - * be infinite, so all characters up to the end - * of the string are written. - * <dt>%<dd>Write a % character; no argument is - * converted. - *</dl> - *<p> - * If a conversion specification does not match one of - * the above forms, an IllegalArgumentException is - * thrown and the instance of PrintfFormat is not - * created.</p> - *<p> - * If a floating point value is the internal - * representation for infinity, the output is - * [+]Infinity, where Infinity is either Infinity or - * Inf, depending on the desired output string length. - * Printing of the sign follows the rules described - * above.</p> - *<p> - * If a floating point value is the internal - * representation for "not-a-number," the output is - * [+]NaN. Printing of the sign follows the rules - * described above.</p> - *<p> - * In no case does a non-existent or small field width - * cause truncation of a field; if the result of a - * conversion is wider than the field width, the field - * is simply expanded to contain the conversion result. - *</p> - *<p> - * The behavior is like printf. One exception is that - * the minimum number of exponent digits is 3 instead - * of 2 for e and E formats when the optional L is used - * before the e, E, g, or G conversion character. The - * optional L does not imply conversion to a long long - * double. </p> - * <p> - * The biggest divergence from the C printf - * specification is in the use of 16 bit characters. - * This allows the handling of characters beyond the - * small ASCII character set and allows the utility to - * interoperate correctly with the rest of the Java - * runtime environment.</p> - *<p> - * Omissions from the C printf specification are - * numerous. All the known omissions are present - * because Java never uses bytes to represent - * characters and does not have pointers:</p> - *<ul> - * <li>%c is the same as %C. - * <li>%s is the same as %S. - * <li>u, p, and n conversion characters. - * <li>%ws format. - * <li>h modifier applied to an n conversion character. - * <li>l (ell) modifier applied to the c, n, or s - * conversion characters. - * <li>ll (ell ell) modifier to d, i, o, u, x, or X - * conversion characters. - * <li>ll (ell ell) modifier to an n conversion - * character. - * <li>c, C, d,i,o,u,x, and X conversion characters - * apply to Byte, Character, Short, Integer, Long - * types. - * <li>f, e, E, g, and G conversion characters apply - * to Float and Double types. - * <li>s and S conversion characters apply to String - * types. - * <li>All other reference types can be formatted - * using the s or S conversion characters only. - *</ul> - * <p> - * Most of this specification is quoted from the Unix - * man page for the sprintf utility.</p> - * - * @author Allan Jacobs - * @version 1 - * Release 1: Initial release. - * Release 2: Asterisk field widths and precisions - * %n$ and *m$ - * Bug fixes - * g format fix (2 digits in e form corrupt) - * rounding in f format implemented - * round up when digit not printed is 5 - * formatting of -0.0f - * round up/down when last digits are 50000... - */ -public class PrintfFormat { - /** - * Constructs an array of control specifications - * possibly preceded, separated, or followed by - * ordinary strings.
