Nested Class Summary

Nested Classes

Modifier and Type	Interface and Description
static class	MemberSubstitution.Substitution.Chain A substitution chain allows for chaining multiple substitution steps for a byte code element being replaced.
static interface	MemberSubstitution.Substitution.Factory A factory for creating a substitution for an instrumented method.
static class	MemberSubstitution.Substitution.ForFieldAccess A substitution with a field access.
static class	MemberSubstitution.Substitution.ForMethodInvocation A substitution with a method invocation.
static class	MemberSubstitution.Substitution.ForValue A substitution that loads a fixed value.
static class	MemberSubstitution.Substitution.Stubbing A substitution that drops any field or method access and returns the expected return type's default value, i.e null or zero for primitive types.

Method Summary

Modifier and Type	Method and Description
StackManipulation	resolve(TypeDescription receiver, ByteCodeElement.Member original, TypeList.Generic parameters, TypeDescription.Generic result, JavaConstant.MethodHandle methodHandle, StackManipulation stackManipulation, int freeOffset) Resolves this substitution into a stack manipulation.

Method Detail

resolve

StackManipulation resolve(TypeDescription receiver,
                          ByteCodeElement.Member original,
                          TypeList.Generic parameters,
                          TypeDescription.Generic result,
                          JavaConstant.MethodHandle methodHandle,
                          StackManipulation stackManipulation,
                          int freeOffset)

Resolves this substitution into a stack manipulation.

Parameters:

receiver - The target type on which a member is accessed.

original - The field, method or constructor 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.

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.
