All Implemented Interfaces:

EOKeyValueArchiving, ERDComputingAssignmentInterface, Serializable

public class ERDDefaultIDAssignment
extends ERDAssignment

An assignment to auto-compute a unique(ish), human-readable DOM ids from the d2wContext for Selenium, CSS, Ajax, Javascript, etc. For Ajax updates you may also use this assignment to compute an updateContainerID key (by setting it to idForSection, idForPageConfiguration, etc. as required). This assignment provids defaults for the following keys:

• idForProperty
• idForSection
• idForPageConfiguration
• idForEmbeddedPageConfiguration
• idForEmbeddedProperty
• idForForm

To use: Bind D2W component id binding to d2wContext.id (or d2wContext.idForProperty or d2wContext.idForSection, etc) You may also override these auto computed id by setting rules for the above keys, if necessary.

Constructor Detail

ERDDefaultIDAssignment

public ERDDefaultIDAssignment(EOKeyValueUnarchiver u)

Public constructor

Parameters:

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

ERDDefaultIDAssignment

public ERDDefaultIDAssignment(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

idForProperty

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

a DOM id based on the triple

Parameters:

c - d2w context

Returns:

an id representing the TODO Maybe change to pageConfig + propertyKey?

idForEmbeddedProperty

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

a DOM id based on the triple

Parameters:

c - d2w context

Returns:

an id representing the TODO Maybe change to pageConfig + propertyKey?

idForPageConfiguration

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

A DOM id based on the pageConfig

Parameters:

c - d2w context

Returns:

an id representing the

idForEmbeddedPageConfiguration

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

A DOM id based on the pageConfig + primaryKey

Parameters:

c - d2w context

Returns:

an id representing the

idForSection

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

A DOM id based on the pageConfig and sectionKey

Parameters:

c - d2w context

Returns:

an id representing the section in a tab page

idForForm

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

A DOM id based on the pageConfig

Parameters:

c - d2w context

Returns:

an id representing the form for the d2w page
