Class ERDKeyValueAssignment

java.lang.Object

com.webobjects.directtoweb.Assignment

er.directtoweb.assignments.ERDKeyValueAssignment

All Implemented Interfaces:

EOKeyValueArchiving, Serializable

public class ERDKeyValueAssignment
extends com.webobjects.directtoweb.Assignment

Piece of crap. This assignment works around the fact that KeyValueAssignment isn't public (and should be). Use this assignment as a drop in replacement for KeyValueAssignment. Note that this assignment is not a delayed assignment and as such the value returned by this assignment will be cached the first time this assignment is fired. To have a key value assignment that does not cache the value returned the first time have a look at ERDDelayedKeyValueAssignment.

Constructor Detail

ERDKeyValueAssignment

public ERDKeyValueAssignment(String s,
                             String s1)

Public constructor

Parameters:

s - context key

s1 - value to be invoke on the context when firing.

ERDKeyValueAssignment

public ERDKeyValueAssignment(EOKeyValueUnarchiver eokeyvalueunarchiver)

Public constructor

Parameters:

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

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

fire

public Object fire(com.webobjects.directtoweb.D2WContext d2wcontext)

Fires the assignment. In this case this method calls valueForKeyPath on the passed in context using the value() as the key.

Overrides:

fire in class com.webobjects.directtoweb.Assignment

Parameters:

d2wcontext - current context

Returns:

result of resolving the key path off of the context.
