typeDescription - The type of the represented stack manipulation.

Method Detail

make

public MemberSubstitution.Substitution<MemberSubstitution.Target> make(TypeDescription instrumentedType,
                                                                       MethodDescription instrumentedMethod,

Specified by:

make in interface MemberSubstitution.Substitution.Factory<MemberSubstitution.Target>

Parameters:

instrumentedType - The instrumented type.

instrumentedMethod - The instrumented method.

typePool - The type pool being used.

Returns:

The substitution to apply within the instrumented method.

resolve

public StackManipulation resolve(MemberSubstitution.Target target,
                                 TypeList.Generic parameters,
                                 TypeDescription.Generic result,
                                 JavaConstant.MethodHandle methodHandle,
                                 StackManipulation stackManipulation,
                                 int freeOffset)

Resolves this substitution into a stack manipulation.

Specified by:

resolve in interface MemberSubstitution.Substitution<MemberSubstitution.Target>

Parameters:

target - The targeted member that is substituted.

parameters - All parameters that serve as input to this access.

result - The result that is expected from the interaction or void if no result is expected.

methodHandle - A method handle describing the substituted expression.

stackManipulation - The original byte code expression that is being executed.
