Class MemberSubstitution.Substitution.Chain.Step.ForInvocation

java.lang.Object

net.bytebuddy.asm.MemberSubstitution.Substitution.Chain.Step.ForInvocation

All Implemented Interfaces:

MemberSubstitution.Substitution.Chain.Step<MemberSubstitution.Target>

Enclosing interface:

MemberSubstitution.Substitution.Chain.Step<U extends MemberSubstitution.Target>

@Enhance
public static class MemberSubstitution.Substitution.Chain.Step.ForInvocation
extends java.lang.Object
implements MemberSubstitution.Substitution.Chain.Step<MemberSubstitution.Target>

A step for invoking a method or constructor. If non-static, a method is invoked upon a the current stack argument of the chain. Arguments are loaded from the intercepted byte code element with a possibility of substitution.

Resolves this step of a substitution chain.

Specified by:

resolve in interface MemberSubstitution.Substitution.Chain.Step<MemberSubstitution.Target>

Parameters:

target - The target member of invokedynamic invocation.

parameters - The parameters of the substituted element.

result - The resulting type of the substituted element.

methodHandle - A method handle of the stackManipulation invocation that is being substituted.

stackManipulation - The byte code instruction that is being substituted.

current - The current type of the applied substitution that is the top element on the operand stack.

offsets - The arguments of the substituted byte code element mapped to their local variable offsets.

freeOffset - The first free offset in the local variable array.

Returns:

A resolved substitution step for the supplied inputs.
