Package org.perfectable.introspection

Class FunctionalReference.PartialVisitor<T>

java.lang.Object

org.perfectable.introspection.FunctionalReference.PartialVisitor<T>

Type Parameters:

T - type of return value from visitor

All Implemented Interfaces:

FunctionalReference.Visitor<T>

Enclosing interface:

FunctionalReference

public abstract static class FunctionalReference.PartialVisitor<T>
extends Object
implements FunctionalReference.Visitor<T>

Visitor Pattern partial implementation that allows handling of groups of modes.

Calls fallback() on any unimplemented method. If visitMethod(java.lang.reflect.Method) is overridden, it is called when mode is "static", "instance" or "bound".

Method Detail

visitStatic

public T visitStatic(Method method)

Description copied from interface: FunctionalReference.Visitor

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

Specified by:

visitStatic in interface FunctionalReference.Visitor<T>

Parameters:

method - method to which this functional references refers

Returns:

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

visitInstance

public T visitInstance(Method method)

Description copied from interface: FunctionalReference.Visitor

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

Specified by:

visitInstance in interface FunctionalReference.Visitor<T>

Parameters:

method - method to which this functional references refers

Returns:

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

visitBound

public T visitBound(Method method,
                    Object boundInstance)

Description copied from interface: FunctionalReference.Visitor

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

Specified by:

visitBound in interface FunctionalReference.Visitor<T>

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

public T visitConstructor(Constructor<?> constructor)

Description copied from interface: FunctionalReference.Visitor

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

Specified by:

visitConstructor in interface FunctionalReference.Visitor<T>

Parameters:

constructor - constructor to which this functional references refers

Returns:

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

visitLambda

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

Description copied from interface: FunctionalReference.Visitor

Executes when mode of this reference is "lambda".

Specified by:

visitLambda in interface FunctionalReference.Visitor<T>

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>)

visitMethod

protected T visitMethod(Method method)

Executes when mode of this reference is "static", "instance" or "bound".

Parameters:

method - method that this reference refers to

Returns:

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

fallback

protected abstract T fallback()

Executes when mode was not overridden.

Returns:

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