/**
* This class implements the processing necessary to perform an LDAPv3 compare
* operation, which may be used to determine whether a specified entry contains
* a given attribute value. Compare requests include the DN of the target
* entry, the name of the target attribute, and the value for which to make the
* determination. It may also include a set of controls to send to the server.
*
* The assertion value may be specified as either a string or a byte array. If
* it is specified as a byte array, then it may represent either a binary or a
* string value. If a string value is provided as a byte array, then it should
* use the UTF-8 encoding for that value.
*
* {@code CompareRequest} objects are mutable and therefore can be altered and
* re-used for multiple requests. Note, however, that {@code CompareRequest}
* objects are not threadsafe and therefore a single {@code CompareRequest}
* object instance should not be used to process multiple requests at the same
* time.
*
*
Example
* The following example demonstrates the process for performing a compare
* operation:
*
* CompareRequest compareRequest =
* new CompareRequest("dc=example,dc=com", "description", "test");
* CompareResult compareResult;
* try
* {
* compareResult = connection.compare(compareRequest);
*
* // The compare operation didn't throw an exception, so we can try to
* // determine whether the compare matched.
* if (compareResult.compareMatched())
* {
* // The entry does have a description value of test.
* }
* else
* {
* // The entry does not have a description value of test.
* }
* }
* catch (LDAPException le)
* {
* // The compare operation failed.
* compareResult = new CompareResult(le.toLDAPResult());
* ResultCode resultCode = le.getResultCode();
* String errorMessageFromServer = le.getDiagnosticMessage();
* }
*
