Method Detail

visitStatic

T visitStatic(Method method)

Executes when mode of this reference is "static", i.e. this is a reference to static method.

Parameters:

method - method to which this functional references refers

Returns:

value passed out of FunctionalReference.Introspection.visit(org.perfectable.introspection.FunctionalReference.Visitor<T>)

visitInstance

T visitInstance(Method method)

Executes when mode of this reference is "instance", i.e. this is a reference to instance method without bound instance.

Parameters:

method - method to which this functional references refers

Returns:

value passed out of FunctionalReference.Introspection.visit(org.perfectable.introspection.FunctionalReference.Visitor<T>)

visitBound

T visitBound(Method method,
             Object boundInstance)

Executes when mode of this reference is "bound", i.e. this is a reference to instance method with bound instance present.

Parameters:

method - method to which this functional references refers

boundInstance - instance that was used to create reference

Returns:

value passed out of FunctionalReference.Introspection.visit(org.perfectable.introspection.FunctionalReference.Visitor<T>)

visitConstructor

T visitConstructor(Constructor<?> constructor)

Executes when mode of this reference is "constructor", i.e. this is a reference to constructor.

Parameters:

constructor - constructor to which this functional references refers

Returns:

value passed out of FunctionalReference.Introspection.visit(org.perfectable.introspection.FunctionalReference.Visitor<T>)

visitLambda

T visitLambda(Method method,
              List<Object> captures)

Executes when mode of this reference is "lambda".

Parameters:

method - synthetic method that this lambda created

captures - captures caught by this lambda

Returns:

value passed out of FunctionalReference.Introspection.visit(org.perfectable.introspection.FunctionalReference.Visitor<T>)
