Class REProgram
java.lang.Objectcom.jcorporate.expresso.ext.regexp.REProgram
Deprecated. since v5.6, use jakarta oro
- public class REProgram
- extends java.lang.Object
A class that holds compiled regular expressions. This is exposed mainly for use by the recompile utility (which helps you produce precompiled REProgram objects). You should not otherwise need to work directly with this class.

getInstructions
public char[] getInstructions()
- Deprecated.
- Returns a copy of the current regular expression program in a character array that is exactly the right length to hold the program. If there is no program compiled yet, getInstructions() will return null.

setInstructions
public void setInstructions(char[] instruction,
int lenInstruction)
- Deprecated.
- Sets a new regular expression program to run. It is this method which performs any special compile-time search optimizations. Currently only two optimizations are in place - one which checks for backreferences (so that they can be lazily allocated) and another which attempts to find an prefix anchor string so that substantial amounts of input can potentially be skipped without running the actual program.
