  +--org.apache.oro.text.regex.Perl5Pattern

All Implemented Interfaces:

Cloneable, Pattern, Serializable

public final class Perl5Pattern

extends Object

implements Pattern, Serializable, Cloneable

Untamed: An implementation of the Pattern interface for Perl5 regular expressions. This class is compatible with the Perl5Compiler and Perl5Matcher classes. When a Perl5Compiler instance compiles a regular expression pattern, it produces a Perl5Pattern instance containing internal data structures used by Perl5Matcher to perform pattern matches. This class cannot be subclassed and cannot be directly instantiated by the programmer as it would not make sense. Perl5Pattern instances should only be created through calls to a Perl5Compiler instance's compile() methods. The class implements the Serializable interface so that instances may be pre-compiled and saved to disk if desired.
