Method Summary

Dynamic	chainingSend(String selector, Object... args) Sends a message to this Dynamic, as defined by Dynamic.send(String, Object...), and returns the message result wrapped as a dynamic, or Dynamics.null_(), if the result was null.
<T> T	send(String selector, Object... args) Sends a message to this Dynamic, and returns the message result If there is no method matching for the given selector and argument count and types, the message is said to not being understood and a MessageNotUnderstoodException is thrown If there exists more than one method matching the given selector and arguments count and types, Dynamic makes no assumptions about which one will be evaluated.
Object	value() Answers the object wrapped by this dynamic

Method Detail

send

public <T> T send(@NonNull
                  String selector,
                  @NonNull
                  Object... args)

Description copied from interface: Dynamic

Sends a message to this Dynamic, and returns the message result If there is no method matching for the given selector and argument count and types, the message is said to not being understood and a MessageNotUnderstoodException is thrown If there exists more than one method matching the given selector and arguments count and types, Dynamic makes no assumptions about which one will be evaluated.

Parameters:

selector - the message name

args - the message arguments

Returns:

the message result

chainingSend

public Dynamic chainingSend(String selector,
                            Object... args)

Description copied from interface: Dynamic

Sends a message to this Dynamic, as defined by Dynamic.send(String, Object...), and returns the message result wrapped as a dynamic, or Dynamics.null_(), if the result was null. If the message is not understood, instead of throwing an exception, this method returns the null dynamic. This method makes chaining dynamic methods easier. Example:

 Dynamics.from(anObject).$("getFoo").$("getBar").$("getBaz").value()
 

This will return the messages chain result, or null, if any message of the chain returned null or was not understood

Returns:

the null dynamic if the message was not understood or if answered null. The message result, wrapped as a Dynamic, otherwise.
