EvaluableAction

public class InstanceMethodAction

extends MessageAction

An evaluable action which sends an instance message to an object.

A number of static create factory methods are provided to make it easy to construct the common flavors of instance method actions. The creation services provide the notational simplicity of one-line expressions in initialization logic for common cases.

Method Detail

create

public static InstanceMethodAction create(java.lang.Object anInstance,
                                          java.lang.String selector)

Create an action which will send the no-argument message selector to anInstance when it is evaluated.

create

public static InstanceMethodAction create(java.lang.Object anInstance,
                                          java.lang.String selector,
                                          java.lang.Class[] parmTypes)

Create an action which will send the message selector with the argument type signature specified by the parmTypes argument types list to anInstance when it is evaluated.

The client must provide the argument values when the action is evaluated.

create

public static InstanceMethodAction create(java.lang.Object anInstance,
                                          java.lang.String selector,
                                          java.lang.Class[] parmTypes,
                                          java.lang.Object[] args)

create

public static InstanceMethodAction create(java.lang.Object anInstance,
                                          java.lang.reflect.Method aMethod,
                                          java.lang.Object[] args)

Create an action which will send the message represented by aMethod to anInstance with the argument values in args when it is evaluated.

The client may override the default argument values of the action by providing actual argument values when the action is evaluated.

findMethod

public static java.lang.reflect.Method findMethod(java.lang.Object anInstance,
                                                  java.lang.String selector)

Answer the public no-argument instance method named selector supported by anInstance.
