setFilterExpression
public void setFilterExpression(java.lang.String regex)
throws MalformedCachePatternException
- Set the regular expression on which to filter.
- Parameters:
regex
- The regular expression on which to filter.- Throws:
MalformedCachePatternException
- If there is an error in
compiling the regular expression. This need not be caught if
you are using a hard-coded expression that you know is correct.
But for robustness and reliability you should catch this exception
for dynamically entered expressions determined at runtime.

- Parameters:
regex
- The regular expression on which to filter.options
- A set of compilation options specific to the regular
expression grammar being used.- Throws:
MalformedCachePatternException
- If there is an error in
compiling the regular expression. This need not be caught if
