<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>A mutable set of Unicode characters and multicharacter strings. </p>
<p>Objects of this class represent <em>character classes</em> used in regular expressions. A character specifies a subset of Unicode code points. Legal code points are U+0000 to U+10FFFF, inclusive.</p>
<p>The <a class="el" href="classUnicodeSet.html" title="A mutable set of Unicode characters and multicharacter strings.">UnicodeSet</a> class is not designed to be subclassed.</p>
<p><code><a class="el" href="classUnicodeSet.html" title="A mutable set of Unicode characters and multicharacter strings.">UnicodeSet</a></code> supports two APIs. The first is the <em>operand</em> API that allows the caller to modify the value of a <code><a class="el" href="classUnicodeSet.html" title="A mutable set of Unicode characters and multicharacter strings.">UnicodeSet</a></code> object. It conforms to Java 2's <code>java.util.Set</code> interface, although <code><a class="el" href="classUnicodeSet.html" title="A mutable set of Unicode characters and multicharacter strings.">UnicodeSet</a></code> does not actually implement that interface. All methods of <code>Set</code> are supported, with the modification that they take a character range or single character instead of an <code>Object</code>, and they take a <code><a class="el" href="classUnicodeSet.html" title="A mutable set of Unicode characters and multicharacter strings.">UnicodeSet</a></code> instead of a <code>Collection</code>. The operand API may be thought of in terms of boolean logic: a boolean OR is implemented by <code>add</code>, a boolean AND is implemented by <code>retain</code>, a boolean XOR is implemented by <code>complement</code> taking an argument, and a boolean NOT is implemented by <code>complement</code> with no argument. In terms of traditional set theory function names, <code>add</code> is a union, <code>retain</code> is an intersection, <code>remove</code> is an asymmetric difference, and <code>complement</code> with no argument is a set complement with respect to the superset range <code>MIN_VALUE-MAX_VALUE</code></p>
<p>The second API is the <code><a class="el" href="classUnicodeSet.html#a92ea00fbad175397371e02f0a4a7f6cc" title="Modifies this set to represent the set specified by the given pattern, optionally...">applyPattern()</a></code>/<code><a class="el" href="classUnicodeSet.html#a7aa98466d94bcbdcfcf79f57e171c8e7" title="Returns a string representation of this set.">toPattern()</a></code> API from the <code>java.text.Format</code>-derived classes. Unlike the methods that add characters, add categories, and control the logic of the set, the method <code><a class="el" href="classUnicodeSet.html#a92ea00fbad175397371e02f0a4a7f6cc" title="Modifies this set to represent the set specified by the given pattern, optionally...">applyPattern()</a></code> sets all attributes of a <code><a class="el" href="classUnicodeSet.html" title="A mutable set of Unicode characters and multicharacter strings.">UnicodeSet</a></code> at once, based on a string pattern.</p>
<p><b>Pattern syntax</b></p>
<p>Patterns are accepted by the constructors and the <code><a class="el" href="classUnicodeSet.html#a92ea00fbad175397371e02f0a4a7f6cc" title="Modifies this set to represent the set specified by the given pattern, optionally...">applyPattern()</a></code> methods and returned by the <code><a class="el" href="classUnicodeSet.html#a7aa98466d94bcbdcfcf79f57e171c8e7" title="Returns a string representation of this set.">toPattern()</a></code> method. These patterns follow a syntax similar to that employed by version 8 regular expression character classes. Here are some simple examples:</p>
<blockquote> <table border="1" cellspacing="3" cellpadding="3">

</td></tr>
<tr>
<td valign="top" align="left"><p><code>[\p{Lu}]</code> </p>
</td><td valign="top"><p>All characters in the general category Uppercase Letter </p>
</td></tr>
</table>
</blockquote><p>Any character may be preceded by a backslash in order to remove any special meaning. White space characters, as defined by UCharacter.isWhitespace(), are ignored, unless they are escaped.</p>
<p>Property patterns specify a set of characters having a certain property as defined by the Unicode standard. Both the POSIX-like "[:Lu:]" and the Perl-like syntax "\\p{Lu}" are recognized. For a complete list of supported property patterns, see the User's Guide for <a class="el" href="classUnicodeSet.html" title="A mutable set of Unicode characters and multicharacter strings.">UnicodeSet</a> at <a href="http://icu-project.org/userguide/unicodeSet.html">http://icu-project.org/userguide/unicodeSet.html</a>. Actual determination of property data is defined by the underlying Unicode database as implemented by UCharacter.</p>
<p>Patterns specify individual characters, ranges of characters, and Unicode property sets. When elements are concatenated, they specify their union. To complement a set, place a '^' immediately after the opening '['. Property patterns are inverted by modifying their delimiters; "[:^foo]" and "\\P{foo}". In any other location, '^' has no special meaning.</p>
<p>Ranges are indicated by placing two a '-' between two characters, as in "a-z". This specifies the range of all characters from the left to the right, in Unicode order. If the left character is greater than or equal to the right character it is a syntax error. If a '-' occurs as the first character after the opening '[' or '[^', or if it occurs as the last character before the closing ']', then it is taken as a literal. Thus "[a\-b]", "[-ab]", and "[ab-]" all indicate the same set of three characters, 'a', 'b', and '-'.</p>
<p>Sets may be intersected using the '&' operator or the asymmetric set difference may be taken using the '-' operator, for example, "[[:L:]&[\\u0000-\\u0FFF]]" indicates the set of all Unicode letters with values less than 4096. Operators ('&' and '|') have equal precedence and bind left-to-right. Thus "[[:L:]-[a-z]-[\\u0100-\\u01FF]]" is equivalent to "[[[:L:]-[a-z]]-[\\u0100-\\u01FF]]". This only really matters for difference; intersection is commutative.</p>

<li>Most <a class="el" href="classUnicodeSet.html" title="A mutable set of Unicode characters and multicharacter strings.">UnicodeSet</a> methods do not take a UErrorCode parameter because there are usually very few opportunities for failure other than a shortage of memory, error codes in low-level C++ string methods would be inconvenient, and the error code as the last parameter (ICU convention) would prevent the use of default parameter values. Instead, such methods set the <a class="el" href="classUnicodeSet.html" title="A mutable set of Unicode characters and multicharacter strings.">UnicodeSet</a> into a "bogus" state (see <a class="el" href="classUnicodeSet.html#ad2987ff72267bd6692c57be0f0e39418" title="Determine if this object contains a valid set.">isBogus()</a>) if an error occurs.</li>

<p>The array starts with a header. After the header are n bmp code points, then m supplementary code points. Either n or m or both may be zero. n+2*m is always <= 0x7FFF.</p>
<p>If there are no supplementary characters (if m==0) then the header is one 16-bit integer, 'length', with value n.</p>
