resolve
StackManipulation resolve(T target, TypeList.Generic parameters, TypeDescription.Generic result, JavaConstant.MethodHandle methodHandle, StackManipulation stackManipulation, int freeOffset)
Resolves this substitution into a stack manipulation.- 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 orvoid
if no result is expected.methodHandle
- A method handle describing the substituted expression.stackManipulation
- The original byte code expression that is being executed.freeOffset
- The first free offset of the local variable array that can be used for storing values.- Returns:
- A stack manipulation that represents the access.
