Parameters:

index - The index of the argument to load.

Method Details

ofTarget

public static MemberSubstitution.Substitution.Chain.Step.Factory<MemberSubstitution.Target> ofTarget(int index)

Creates a factory that loads the argument for the targeted value's parameter of the specified index.

Parameters:

index - The index to load.

Returns:

An appropriate factory.

ofInstrumentedMethod

public static MemberSubstitution.Substitution.Chain.Step.Factory<MemberSubstitution.Target> ofInstrumentedMethod(int index)

 MethodDescription instrumentedMethod)

Creates a substitution step for an instrumented method.

Specified by:

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

Parameters:

assigner - The assigner to use.

typing - The typing to use.

instrumentedType - The instrumented type.

instrumentedMethod - The instrumented method.

Returns:

The substitution step to apply.

resolve

public MemberSubstitution.Substitution.Chain.Step.Resolution resolve(MemberSubstitution.Target 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.
