Class ERDTabDictionaryComputer

java.lang.Object
  com.webobjects.directtoweb.Assignment
      com.webobjects.directtoweb.TabDictionaryComputer
          er.directtoweb.assignments.ERDTabDictionaryComputer

All Implemented Interfaces:

EOKeyValueArchiving, ERDComputingAssignmentInterface, Serializable

public class ERDTabDictionaryComputer
extends com.webobjects.directtoweb.TabDictionaryComputer
implements ERDComputingAssignmentInterface

This class is needed because the original tab dictionary computer does implement the computing interface and as such does not work with the new caching scheme.

Constructor Detail

ERDTabDictionaryComputer

public ERDTabDictionaryComputer(EOKeyValueUnarchiver u)

Public constructor

Parameters:

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

ERDTabDictionaryComputer

public ERDTabDictionaryComputer(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

dependentKeys

public NSArray dependentKeys(String keyPath)

Implementation of the ERDComputingAssignmentInterface. This assignment depends upon the context key: "displayPropertyKeys". 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.
