Uses of MethodHandle in java.lang.invoke

Methods in java.lang.invoke that return MethodHandle

Modifier and Type	Method and Description
MethodHandle	MethodHandle.asCollector(Class<?> arrayType, int arrayLength) Makes an array-collecting method handle, which accepts a given number of trailing positional arguments and collects them into an array argument.
MethodHandle	MethodHandle.asFixedArity() Makes a fixed arity method handle which is otherwise equivalent to the current method handle.
MethodHandle	MethodHandle.asSpreader(Class<?> arrayType, int arrayLength) Makes an array-spreading method handle, which accepts a trailing array argument and spreads its elements as positional arguments.
MethodHandle	MethodHandle.asType(MethodType newType) Produces an adapter method handle which adapts the type of the current method handle to a new type.
MethodHandle	MethodHandle.asVarargsCollector(Class<?> arrayType) Makes a variable arity adapter which is able to accept any number of trailing positional arguments and collect them into an array argument.
MethodHandle	MethodHandles.Lookup.bind(Object receiver, String name, MethodType type) Produces an early-bound method handle for a non-static method.
MethodHandle	MethodHandle.bindTo(Object x) Binds a value x to the first argument of a method handle, without invoking it.
abstract MethodHandle	CallSite.dynamicInvoker() Produces a method handle equivalent to an invokedynamic instruction which has been linked to this call site.
MethodHandle	MethodHandles.Lookup.findConstructor(Class<?> refc, MethodType type) Produces a method handle which creates an object and initializes it, using the constructor of the specified type.
MethodHandle	MethodHandles.Lookup.findGetter(Class<?> refc, String name, Class<?> type) Produces a method handle giving read access to a non-static field.
MethodHandle	MethodHandles.Lookup.findSetter(Class<?> refc, String name, Class<?> type) Produces a method handle giving write access to a non-static field.
MethodHandle	MethodHandles.Lookup.findSpecial(Class<?> refc, String name, MethodType type, Class<?> specialCaller) Produces an early-bound method handle for a virtual method.
MethodHandle	MethodHandles.Lookup.findStatic(Class<?> refc, String name, MethodType type) Produces a method handle for a static method.
MethodHandle	MethodHandles.Lookup.findStaticGetter(Class<?> refc, String name, Class<?> type) Produces a method handle giving read access to a static field.
MethodHandle	MethodHandles.Lookup.findStaticSetter(Class<?> refc, String name, Class<?> type) Produces a method handle giving write access to a static field.
MethodHandle	MethodHandles.Lookup.findVirtual(Class<?> refc, String name, MethodType type) Produces a method handle for a virtual method.
abstract MethodHandle	CallSite.getTarget() Returns the target method of the call site, according to the behavior defined by this call site's specific class.
MethodHandle	MethodHandles.Lookup.unreflect(Method m) Makes a direct method handle to m, if the lookup class has permission.
MethodHandle	MethodHandles.Lookup.unreflectConstructor(Constructor<?> c) Produces a method handle for a reflected constructor.
MethodHandle	MethodHandles.Lookup.unreflectGetter(Field f) Produces a method handle giving read access to a reflected field.
MethodHandle	MethodHandles.Lookup.unreflectSetter(Field f) Produces a method handle giving write access to a reflected field.
MethodHandle	MethodHandles.Lookup.unreflectSpecial(Method m, Class<?> specialCaller) Produces a method handle for a reflected method.

Methods in java.lang.invoke with parameters of type MethodHandle

Modifier and Type	Method and Description
static CallSite	LambdaMetafactory.metafactory(MethodHandles.Lookup caller, String invokedName, MethodType invokedType, MethodType samMethodType, MethodHandle implMethod, MethodType instantiatedMethodType) Facilitates the creation of simple "function objects" that implement one or more interfaces by delegation to a provided MethodHandle, after appropriate type adaptation and partial evaluation of arguments.
static <T extends Member> T	MethodHandles.reflectAs(Class<T> expected, MethodHandle target) Performs an unchecked "crack" of a direct method handle.
abstract void	CallSite.setTarget(MethodHandle newTarget) Updates the target method of this call site, according to the behavior defined by this call site's specific class.
