Class ERDDelayedObjectCreationAssignment

java.lang.Object

com.webobjects.directtoweb.Assignment

er.directtoweb.assignments.delayed.ERDDelayedAssignment

er.directtoweb.assignments.delayed.ERDDelayedObjectCreationAssignment

All Implemented Interfaces:

EOKeyValueArchiving, Serializable

public class ERDDelayedObjectCreationAssignment
extends ERDDelayedAssignment

Assignment used to create objects on the fly. This assignment can be used in two different manner. The first is by just specifing the class name as a string, ie "foo.bar.MyClass". This will create an instance of the MyClass object. The second form allows one to specify the object to be created in a dictionary format:

 {
        className = "foo.bar.MyClass";
        arguments = ( {
                        className = "com.webobjects.appserver.WOSession";
                        contextKey = "session";
                }, {
                        className = "java.lang.String";
                        contextKey = "propertyKey";
                });
 }

This will create an object of type MyClass using the constructor: MyClass(WOSession session, String key), using the arguments found by resolving the contextKey off of the current context.

Constructor Detail

ERDDelayedObjectCreationAssignment

public ERDDelayedObjectCreationAssignment(EOKeyValueUnarchiver u)

Public constructor

Parameters:

u - key-value unarchiver used when unarchiving from rule files.

ERDDelayedObjectCreationAssignment

public ERDDelayedObjectCreationAssignment(String key,
                                          Object value)

Public constructor

Parameters:

key - context key

value - of the assignment

Method Detail

decodeWithKeyValueUnarchiver

public static Object decodeWithKeyValueUnarchiver(EOKeyValueUnarchiver eokeyvalueunarchiver)

Static constructor required by the EOKeyValueUnarchiver interface. If this isn't implemented then the default behavior is to construct the first super class that does implement this method. Very lame.

Parameters:

eokeyvalueunarchiver - to be unarchived

Returns:

decoded assignment of this class

fireNow

public Object fireNow(com.webobjects.directtoweb.D2WContext context)

Delayed firing of assignment. Creates an object for the specified class. See description of the class for the correct format.

Specified by:

fireNow in class ERDDelayedAssignment

Parameters:

context - current context

Returns:

newly created object
