<div class="textblock"><p>The <code><a class="el" href="classCollator.html" title="The Collator class performs locale-sensitive string comparison. ">Collator</a></code> class performs locale-sensitive string comparison. </p>
<p><br/>
You use this class to build searching and sorting routines for natural language text.<br/>
<em>Important: </em>The ICU collation service has been reimplemented in order to achieve better performance and UCA compliance. For details, see the <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">collation design document</a>. </p>
<p><code><a class="el" href="classCollator.html" title="The Collator class performs locale-sensitive string comparison. ">Collator</a></code> is an abstract base class. Subclasses implement specific collation strategies. One subclass, <code><a class="el" href="classRuleBasedCollator.html" title="The RuleBasedCollator class provides the simple implementation of Collator, using data-driven tables...">RuleBasedCollator</a></code>, is currently provided and is applicable to a wide set of languages. Other subclasses may be created to handle more specialized needs. </p>
<p>Like other locale-sensitive classes, you can use the static factory method, <code>createInstance</code>, to obtain the appropriate <code><a class="el" href="classCollator.html" title="The Collator class performs locale-sensitive string comparison. ">Collator</a></code> object for a given locale. You will only need to look at the subclasses of <code><a class="el" href="classCollator.html" title="The Collator class performs locale-sensitive string comparison. ">Collator</a></code> if you need to understand the details of a particular collation strategy or if you need to modify that strategy. </p>
<p>The following example shows how to compare two strings using the <code><a class="el" href="classCollator.html" title="The Collator class performs locale-sensitive string comparison. ">Collator</a></code> for the default locale. <blockquote> <pre>
<div class="fragment"><div class="line">* <span class="comment">// Compare two strings in the default locale</span></div>

</pre> </blockquote> <p>You can set a <code><a class="el" href="classCollator.html" title="The Collator class performs locale-sensitive string comparison. ">Collator</a></code>'s <em>strength</em> property to determine the level of difference considered significant in comparisons. Five strengths are provided: <code>PRIMARY</code>, <code>SECONDARY</code>, <code>TERTIARY</code>, <code>QUATERNARY</code> and <code>IDENTICAL</code>. The exact assignment of strengths to language features is locale dependant. For example, in Czech, "e" and "f" are considered primary differences, while "e" and "\u00EA" are secondary differences, "e" and "E" are tertiary differences and "e" and "e" are identical. The following shows how both case and accents could be ignored for US English. <blockquote> <pre>

</pre> </blockquote> <p>For comparing strings exactly once, the <code>compare</code> method provides the best performance. When sorting a list of strings however, it is generally necessary to compare each string multiple times. In this case, sort keys provide better performance. The <code>getSortKey</code> methods convert a string to a series of bytes that can be compared bitwise against other sort keys using <code>strcmp()</code>. Sort keys are written as zero-terminated byte strings. They consist of several substrings, one for each collation strength level, that are delimited by 0x01 bytes. If the string code points are appended for UCOL_IDENTICAL, then they are processed for correct code point order comparison and may contain 0x01 bytes but not zero bytes. </p>
<p>An older set of APIs returns a <code><a class="el" href="classCollationKey.html" title="Collation keys are generated by the Collator class. ">CollationKey</a></code> object that wraps the sort key bytes instead of returning the bytes themselves. Its use is deprecated, but it is still available for compatibility with Java. </p>
<p><b>Note:</b> <code><a class="el" href="classCollator.html" title="The Collator class performs locale-sensitive string comparison. ">Collator</a></code>s with different <a class="el" href="classLocale.html" title="A Locale object represents a specific geographical, political, or cultural region. ">Locale</a>, and CollationStrength settings will return different sort orders for the same set of strings. Locales have specific collation rules, and the way in which secondary and tertiary differences are taken into account, for example, will result in a different sorting order for same strings. </p>

<p>Return value is always the number of bytes needed, regardless of whether the result buffer was big enough or even valid.<br/>
Resulting bounds can be used to produce a range of strings that are between upper and lower bounds. For example, if bounds are produced for a sortkey of string "smith", strings between upper and lower bounds with one level would include "Smith", "SMITH", "sMiTh".<br/>
There are two upper bounds that can be produced. If UCOL_BOUND_UPPER is produced, strings matched would be as above. However, if bound produced using UCOL_BOUND_UPPER_LONG is used, the above example will also match "Smithsonian" and similar.<br/>
