Constructor Detail

ERDImageNameAssignment

public ERDImageNameAssignment(EOKeyValueUnarchiver u)

Public constructor

Parameters:

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

ERDImageNameAssignment

public ERDImageNameAssignment(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 keys: "baseImageDirectory", "sectionKey", and "tabKey". 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.

imageNameForKey

public String imageNameForKey(String key,
                              String baseImageDirectory,
                              String prefix)

sectionImageName

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

tabImageName

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