Method Details

handle

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

Handle any otherwise-unmatched filter specification type. The default implementation returns null.

Parameters:

filterSpec - the filter specification (not null)

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

handle

default R handle(EqualsFilterSpec filterSpec,
 P parameter)
          throws E

Handle an equality filter specification type. The default implementation delegates to handle(FilterSpec,P).

Parameters:

handle

default R handle(GreaterEqualFilterSpec filterSpec,
 P parameter)
          throws E

Handle a greater-than-or-equal-to filter specification type. The default implementation delegates to handle(FilterSpec,P).

Parameters:
