All Implemented Interfaces:

EOKeyValueArchiving, ERDComputingAssignmentInterface, Serializable

public class ERDDefaultClassStringAssignment
extends ERDAssignment

An assignment to auto-compute a unique(ish), human-readable DOM class strings from the d2wContext for Selenium, CSS, Ajax, Javascript, etc. This assignment provides defaults for the following keys:

• classForTask
• classForProperty
• classForColumn

To use: Bind D2W component class binding to d2wContext.class (or d2wContext.classForTask, etc)

Constructor Detail

ERDDefaultClassStringAssignment

public ERDDefaultClassStringAssignment(EOKeyValueUnarchiver u)

Public constructor

Parameters:

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

ERDDefaultClassStringAssignment

public ERDDefaultClassStringAssignment(String key,
                                       Object value)

Public constructor

Parameters:

key - context key

value - of the assignment

Method Detail

dependentKeys

public NSArray dependentKeys(String keyPath)

Implementation of the ERDComputingAssignmentInterface. 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.

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

classForTask

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

A DOM class based on the task and subTask

Parameters:

c - d2w context

Returns:

a class string representing the task

classForProperty

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

A DOM class based on the propertyKey

Parameters:

c - d2w context

Returns:

a class string representing the propertyKey

classForAttribute

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

A DOM class based on the propertyKey

Parameters:

c - d2w context

Returns:

a class string representing the propertyKey along with a class 'attribute'

classForColumn

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

A DOM class based on the propertyKey and componentName

Parameters:

c - d2w context

Returns:

a class string representing the propertyKey and componentName
