HandlerMap

public final class HandlerMap<M extends MessageClass<?>, R extends MessageClass<?>, H extends HandlerMethod<? extends Object, M, ? extends Object, R>> implements Serializable

Provides mapping from a class of messages to methods which handle such messages.

Parameters

<M>

the type of messages

<R>

the type of message classes produced by handler methods

<H>

the type of handler methods

Functions

public boolean containsClass(M messageClass)

Returns true if the handler map contains a method that handles the passed class of messages, false otherwise.

public static HandlerMap<M, P, H> create<M extends MessageClass<?>, P extends MessageClass<?>, H extends HandlerMethod<? extends Object, M, ? extends Object, P>>(Class<? extends Object> declaringClass, MethodSignature<H, ? extends Object> signature)

Creates a map of methods found in the passed class.

public H handlerOf(M messageClass)

Obtains a single handler method for messages of the given class.

public H handlerOf(M messageClass, MessageClass<?> originClass)

Obtains a single handler method for messages of the given class and with the given origin.

public ImmutableSet<H> handlersOf(M messageClass)

Obtains methods for handling messages of the given class.

public ImmutableSet<H> handlersOf(M messageClass, MessageClass<?> originClass)

Obtains methods for handling messages of the given class and with the given origin.

public ImmutableSet<M> messageClasses()

Obtains classes of messages for which handlers are stored in this map.

public ImmutableSet<M> messageClasses(Predicate<? extends Object> predicate)

Obtains classes of messages which handlers satisfy the passed predicate.

public ImmutableCollection<H> methods()

Obtains handler methods matching the passed criteria.

public ImmutableSet<R> producedTypes()

Obtains the classes of messages produced by the handler methods in this map.
