Method Detail

handle

default R handle(FilterSpec filterSpec,
                 P parameter)
          throws E extends Exception

parameter - the parameter passed in to the FilterSpec.accept(Visitor<P, R, E>, P) method

Returns:

the value to return from the FilterSpec.accept(Visitor<P, R, E>, P) method

Throws:

E - to throw this exception from the FilterSpec.accept(Visitor<P, R, E>, P) method

E extends Exception

handle

default R handle(EqualsFilterSpec filterSpec,
                 P parameter)
