Description copied from class: PatternElement
Return whether or not this element matches the given instruction with the given Bindings in effect.

Specified by:
match in class PatternElement
Parameters:
handle - the instruction
cpg - the ConstantPoolGen from the method
before - the ValueNumberFrame representing values in the Java stack frame just before the execution of the instruction
after - the ValueNumberFrame representing values in the Java stack frame just after the execution of the instruction
bindingSet - the set of Bindings
Returns:
if the match is successful, returns a MatchResult with the PatternElement and BindingSet; if the match is not successful, returns null
Throws:
DataflowAnalysisException
