Class RECompiler

java.lang.Object

net.sf.saxon.regex.RECompiler

public class RECompiler
extends Object

A regular expression compiler class. This class compiles a pattern string into a regular expression program interpretable by the RE evaluator class. The 'recompile' command line tool uses this compiler to pre-compile regular expressions for use with RE. For a description of the syntax accepted by RECompiler and what you can do with regular expressions, see the documentation for the RE matcher class.
