Constructor Detail

ERDSortedManyToManyAssignment

public ERDSortedManyToManyAssignment(String key,
                                     Object value)

Public constructor

Parameters:

key - context key

value - of the assignment

ERDSortedManyToManyAssignment

public ERDSortedManyToManyAssignment(com.webobjects.eocontrol.EOKeyValueUnarchiver unarchiver)

Public constructor

Parameters:

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

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 context keys: "propertyKey" and "keyWhenRelationship". This array of keys is used when constructing the significant keys for the passed in keyPath.

Parameters:

keyPath - to compute significant keys for.

Returns:

array of context keys this assignment depends upon.

keyWhenRelationship

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

Called when firing this assignment with the key-path: keyWhenRelationship.

Returns:

the current propertyKey + "." + the current value for keyWhenRelationship.

joinRelationshipsForJoinEntity

public static NSArray joinRelationshipsForJoinEntity(com.webobjects.eoaccess.EOEntity entity)

Calculates the join relationships for a given join entity.

Parameters:

entity - to find join relationships

Returns:

array containing two join relationships
