Method Detail

$

public final Dynamic $(String selector,
                       Object... args)

Description copied from interface: Dynamic

Synonym for Dynamic.chainingSend(String, Object...)

Specified by:

$ in interface Dynamic

Returns:

Dynamic.chainingSend(String, Object...)

delayedSend

@NonNull
public final <T> net.sf.staccatocommons.defs.Thunk<T> delayedSend(@NonNull
                                                                          String selector,
                                                                          @NonNull
                                                                          Object... args)

Description copied from interface: Dynamic

Asynchronously sends a message to this dynamic object by returning a thunk that, when evaluated, performs the actual message passing

Specified by:

delayedSend in interface Dynamic

Parameters:

selector - the message selector

args - the message arguments

Returns:

a thunk that, when evaluted, will send the given message

as

@NonNull
public final <T> T as(@NonNull
                              Class<T> clazz)

Description copied from interface: Dynamic

"casts" this dynamic to the desired type, by returning the wrapped value, if it can be casted to the given class, or by returning a proxy that forwards messages to Dynamic.send(String, Object...), otherwise. Methods must throw ClassCastException if the actual returned value of the dynamic can not be cast the the returned value of the method, and NullPointerException if null is returned when a primitive return type is expected

Specified by:

as in interface Dynamic

Returns:

a new proxy of the given type, that forwards messages to this Dynamic

chainingAs

@NonNull
public final <T> T chainingAs(@NonNull
                                      Class<T> clazz)

Description copied from interface: Dynamic

"casts" this dynamic to the desired type, by returning the wrapped value, if it can be casted to the given class, or by returning a proxy that forwards messages to Dynamic.chainingSend(String, Object...), casting with Dynamic.chainingAs(Class) the result to the desired method return type, otherwise. Methods must throw NullPointerException if null is returned when a primitive return type is expected

Specified by:

chainingAs in interface Dynamic

Returns:

a new proxy of the given type, that forwards messages to this Dynamic
