Class ERDLocalizedAssignment

java.lang.Object

com.webobjects.directtoweb.Assignment

er.directtoweb.assignments.ERDAssignment

er.directtoweb.assignments.ERDLocalizedAssignment

All Implemented Interfaces:

com.webobjects.eocontrol.EOKeyValueArchiving, ERDComputingAssignmentInterface, ERDLocalizableAssignmentInterface, Serializable

public class ERDLocalizedAssignment
extends ERDAssignment
implements ERDLocalizableAssignmentInterface

This assignment runs it's value through the localizer and evaluates it as a template before returning it. Meaning something like *true* => cancelCreationMessage = "ERD2W.cancelCreationMessage" will look up "ERD2W.cancelCreationMessage", then look at the translation and finally parses it with the D2WContext as a parameter. Of course, you can also simply give it a string like "Cancel creating this @@displayNameForEntity@@"

Constructor Detail

ERDLocalizedAssignment

public ERDLocalizedAssignment(com.webobjects.eocontrol.EOKeyValueUnarchiver u)

Public constructor

Parameters:

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

ERDLocalizedAssignment

public ERDLocalizedAssignment(String key,
                              Object value)

Public constructor

Parameters:

key - context key

value - of the assignment

Method Detail

decodeWithKeyValueUnarchiver

public static Object decodeWithKeyValueUnarchiver(com.webobjects.eocontrol.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

dependentKeys

public NSArray dependentKeys(String keyPath)

Implementation of the ERDComputingAssignmentInterface. This assignment depends upon the template keys from the value of this assignment. This array of keys is used when constructing the significant keys for the passed in keyPath.

Specified by:

dependentKeys in interface ERDComputingAssignmentInterface

Parameters:

keyPath - to compute significant keys for.

Returns:

array of context keys this assignment depends upon.

fire

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

Description copied from class: ERDAssignment

Method called to fire an assignment. This method has been enhanced to dynamicly lookup the real method to call based on the return value of keyForMethodLookup. The default implementation will lookup the method based on the key path of the assignment. If you are building a generic assignment like a BooleanAssignment you should override this method seeing as you wouldn't care what the key path of the assignment is. If you would like to provide a different methodology for the method to be fired override the method keyForMethodLookup.

Overrides:

fire in class ERDAssignment

Parameters:

c - current D2W context

Returns:

result of firing the assignment.
