Field Detail

_DEPENDENT_KEYS

public static final NSArray _DEPENDENT_KEYS

holds the array of dependent keys

Constructor Detail

ERDDefaultsEmbeddedAssignment

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

Public constructor

Parameters:

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

ERDDefaultsEmbeddedAssignment

public ERDDefaultsEmbeddedAssignment(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 dependentKeys(String keyPath)

Implementation of the ERDComputingAssignmentInterface. This assignment depends upon the context keys: "propertyKey", "object.entityName", and "embeddedEntityName". 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.

localizerForContext

public ERXLocalizer localizerForContext(com.webobjects.directtoweb.D2WContext c)

Gets the localizer for the current context. Implementation wise all this method does is get the current session from the context and then calls localizerForSession off of ERXLocalizer.

Overrides:

localizerForContext in class ERDAssignment

Parameters:

c - a D2W context

Returns:

localizer for the session stored in the context.

defaultEmbeddedEntityDisplayName

public String defaultEmbeddedEntityDisplayName(com.webobjects.directtoweb.D2WContext c)

Calculates and returns the default embedded entity display name. The results are localized.

Parameters:

c - current context

Returns:

default localized embedded entity name.

defaultEmbeddedDisplayPropertyKeys

public NSArray defaultEmbeddedDisplayPropertyKeys(com.webobjects.directtoweb.D2WContext c)

Calculates the default embedded display property keys for a given context. Implementation wise this method uses the embedded entity to determine what all of the class properties are minus all of the relationship keys.

Parameters:

c - current D2W context

Returns:

array of display keys for the current embedded entity.

defaultEmbeddedEntityName

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

Calculates the default embedded entity name using the current object and propertyKey.

Parameters:

c - current context

Returns:

name of the entity pointed to by the propertyKey off of the object in the context.

defaultEmbeddedListPageConfiguration

public String defaultEmbeddedListPageConfiguration(com.webobjects.directtoweb.D2WContext c)

Calculates and returns the default embedded list page configuration to be used for embedded list pages.

Parameters:

c - current context

Returns:

page configuration of the form: "ListEmbedded" + the the value of the current embeddedEntityname.

defaultEmbeddedInspectPageConfiguration

public String defaultEmbeddedInspectPageConfiguration(com.webobjects.directtoweb.D2WContext c)

Calculates and returns the default embedded inspect page configuration to be used for embedded inspect pages.

Parameters:

c - current context

Returns:

page configuration of the form: "InspectEmbedded" + the the value of the current embeddedEntityname.

defaultEmbeddedEditPageConfiguration

public String defaultEmbeddedEditPageConfiguration(com.webobjects.directtoweb.D2WContext c)

Calculates and returns the default embedded edit page configuration to be used for embedded edit pages.

Parameters:

c - current context

Returns:

page configuration of the form: "EditEmbedded" + the the value of the current embeddedEntityname.

keyForMethodLookup

public String keyForMethodLookup(com.webobjects.directtoweb.D2WContext c)

By default the key path being requested is used as the key to lookup the method to call on the ERDAssignment subclass. However in the case of this assignment we want to use the string value of the value of the assignment as the key to lookup the method. For example if value of this assignment is "foo", then when this assignment is fired the method foo(D2WContext) will be called.

Overrides:

keyForMethodLookup in class ERDAssignment

Parameters:

c - current context

Returns:

key for method lookup, in this case the value of the assignment is returned.
