Constructor Detail

ForAssignment

protected ForAssignment(@MaybeNull
                        TypeDescription.Generic result,
                        Assigner assigner)

Creates a step for a type assignment.

Parameters:

result - The result type or null if the type of the substitution result should be targeted.

assigner - The assigner to use.

Method Detail

castTo

public static MemberSubstitution.Substitution.Chain.Step.Factory castTo(Type type)

Creates a step factory that casts the current stack top value to the specified type.

Parameters:

type - The type that should be cast to.

Returns:

An appropriate step factory.

castTo

public static MemberSubstitution.Substitution.Chain.Step.Factory castTo(TypeDescription.Generic typeDescription)

Creates a step factory that casts the current stack top value to the specified type.

Parameters:

typeDescription - The description of the type that should be cast to.

Returns:

An appropriate step factory.

castToSubstitutionResult

public static MemberSubstitution.Substitution.Chain.Step.Factory castToSubstitutionResult()

Creates a step factory that casts the current stack top value to the expected return value.

Returns:

An appropriate step factory.

resolve

public MemberSubstitution.Substitution.Chain.Step.Resolution resolve(TypeDescription receiver,
                                                                     ByteCodeElement.Member original,

Resolves this step of a substitution chain.

Specified by:

resolve in interface MemberSubstitution.Substitution.Chain.Step

Parameters:

receiver - The target result type of the substitution.

original - The byte code element that is currently substituted.

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.
