Constructor Detail

ERMDAjaxUpdateAssignment

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

Public constructor

Parameters:

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

ERMDAjaxUpdateAssignment

public ERMDAjaxUpdateAssignment(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<String> dependentKeys(String keyPath)

Implementation of the ERDComputingAssignmentInterface.

Returns:

empty array.

shouldObserve

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

Checks whether the current property is declared as to be observed via the propertyDependencies key.

Returns:

true if the current property key is to be observed

isDependent

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

Checks whether the current property is declared dependent via the propertyDependencies key.

Returns:

true if the current property is dependent
