A set of utility methods used for calling across the support library boundary.

Summary

Public constructors
<init>() A set of utility methods used for calling across the support library boundary.

Public methods
open static T	castToSuppLibClass(clazz: Class<T>!, invocationHandler: InvocationHandler!) Returns an implementation of the boundary interface named clazz, by delegating method calls to the InvocationHandler invocationHandler.
open static Boolean	containsFeature(features: MutableCollection<String!>!, soughtFeature: String!) Check whether a set of features {@param features} contains a certain feature {@param * soughtFeature}.
open static Boolean	containsFeature(features: Array<String!>!, soughtFeature: String!)
open static InvocationHandler!	createInvocationHandlerFor(delegate: Any!) Create an java.lang.reflect.InvocationHandler that delegates method calls to {@param delegate}, making sure that the java.lang.reflect.Method and parameters being passed to {@param delegate} exist in the same java.lang.ClassLoader as {@param * delegate}.
open static Array<InvocationHandler!>!	createInvocationHandlersForArray(delegates: Array<Any!>!) Plural version of createInvocationHandlerFor(Object).
open static Method!	dupeMethod(method: Method!, delegateLoader: ClassLoader!) Utility method for fetching a method from {@param delegateLoader}, with the same signature (package + class + method name + parameters) as a given method defined in another classloader.
open static Any!	getDelegateFromInvocationHandler(invocationHandler: InvocationHandler!) Assuming that the given InvocationHandler was created in the current classloader and is an InvocationHandlerWithDelegateGetter, return the object the InvocationHandler delegates its method calls to.
open static Boolean	instanceOfInOwnClassLoader(obj: Any!, className: String!) Check if an object is an instance of className, resolving className in the object's own ClassLoader.

<init>

BoundaryInterfaceReflectionUtil()

A set of utility methods used for calling across the support library boundary.

Public methods

castToSuppLibClass

open static fun <T : Any!> castToSuppLibClass(clazz: Class<T>!, invocationHandler: InvocationHandler!): T

Returns an implementation of the boundary interface named clazz, by delegating method calls to the InvocationHandler invocationHandler.

containsFeature

open static fun containsFeature(features: MutableCollection<String!>!, soughtFeature: String!): Boolean

Check whether a set of features {@param features} contains a certain feature {@param * soughtFeature}.

containsFeature

open static fun containsFeature(features: Array<String!>!, soughtFeature: String!): Boolean

createInvocationHandlerFor

open static fun createInvocationHandlerFor(delegate: Any!): InvocationHandler!

Create an java.lang.reflect.InvocationHandler that delegates method calls to {@param delegate}, making sure that the java.lang.reflect.Method and parameters being passed to {@param delegate} exist in the same java.lang.ClassLoader as {@param * delegate}.

createInvocationHandlersForArray

open static fun createInvocationHandlersForArray(delegates: Array<Any!>!): Array<InvocationHandler!>!

Plural version of createInvocationHandlerFor(Object).

dupeMethod

open static fun dupeMethod(method: Method!, delegateLoader: ClassLoader!): Method!

Utility method for fetching a method from {@param delegateLoader}, with the same signature (package + class + method name + parameters) as a given method defined in another classloader.

getDelegateFromInvocationHandler

open static fun getDelegateFromInvocationHandler(invocationHandler: InvocationHandler!): Any!

Assuming that the given InvocationHandler was created in the current classloader and is an InvocationHandlerWithDelegateGetter, return the object the InvocationHandler delegates its method calls to.

instanceOfInOwnClassLoader

open static fun instanceOfInOwnClassLoader(obj: Any!, className: String!): Boolean

Check if an object is an instance of className, resolving className in the object's own ClassLoader. This is useful when obj may have been created in a ClassLoader other than the current one (in which case obj instanceof Foo would fail but instanceOfInOwnClassLoader(obj, "Foo") may succeed).
