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.
-
setFilterExpression
public void setFilterExpression(java.lang.String regex, int options) throws MalformedCachePatternException
Set the regular expression on which to filter along with any special options to use when compiling the expression.- 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 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.
