org.apache.oro.text.awk
Class AwkPattern  

java.lang.Object
  org.apache.oro.text.awk.AwkPattern

All Implemented Interfaces:

org.apache.oro.text.regex.Pattern, java.io.Serializable

---

public final class AwkPattern

extends java.lang.Object

implements org.apache.oro.text.regex.Pattern, java.io.Serializable

An implementation of the Pattern interface for Awk regular expressions. This class is compatible with the AwkCompiler and AwkMatcher classes. When an AwkCompiler instance compiles a regular expression pattern, it produces an AwkPattern instance containing internal data structures used by AwkMatcher to perform pattern matches. This class cannot be subclassed and cannot be directly instantiated by the programmer as it would not make sense. It is however serializable so that pre-compiled patterns may be saved to disk and re-read at a later time. AwkPattern instances should only be created through calls to an AwkCompiler instance's compile() methods

Since:

1.0

Version:

@version@
