public ClassPathFilter parse(String filterStr)
                      throws IllegalArgumentException

Parses the class filter string into a ClassFilter object.

Strings are of the form:

 FilterName( arg[,arg[,arg[,...]]] )
 

Where FilterName is the name of the desired filter class without the "ClassFilter" ending. (e.g. True() for the class TrueClassFilter).

The result is a prefix notation function. For example:

 Or(Interface(), Not(Prefix(org.xenei)))

Filters that accept a Case as the first argument in the constructor may have the case specified as the first parameter as either Sensitive or Insensitive.

Parameters:

filterStr - The filter definition to parse.

Returns:

The ClassFilter

Throws:

IllegalArgumentException - If the filter can not be build.
