Detailed Description

A bunch of methods used for pulling default values from EOModels.
Provides defaults for the following keys:

Constructor & Destructor Documentation

ERDDefaultModelAssignment ( EOKeyValueUnarchiver  u  ) 

Public constructor

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

ERDDefaultModelAssignment ( String  key,
Object  value 
)

Public constructor

Parameters:
key context key
value of the assignment

Member Function Documentation

Object attributeConstants ( D2WContext  c  ) 

Returns the default value for the entity based on the controllerName.

Parameters:
c current D2W context
Returns:
the entity.

int attributeWidthAsInt ( D2WContext  c  )  [protected]

static Object decodeWithKeyValueUnarchiver ( EOKeyValueUnarchiver  eokeyvalueunarchiver  )  [static]

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

Reimplemented in ERDDefaultsAssignment.

Object defaultSortOrdering ( D2WContext  context  ) 

Called when firing this assignment with the key-path: defaultSortOrdering.

Returns:
the first value of the display property keys, with ascending comparison.

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.

Implements ERDComputingAssignmentInterface.

Object destinationEntity ( D2WContext  c  ) 

Returns the default value for the destination entity. This is a value add because we are now also able to set the destination entity in other rules.

Parameters:
c current D2W context
Returns:
the destination entity.

Object dummyEntity ( D2WContext  c  ) 

Returns a fake entity that can be used for tasks such as error/confirm.

Parameters:
c current D2W context
Returns:
dummy entity.

EOEntity dummyEntity (  )  [protected]

Utility to create a fake entity that can be used for tasks such as error/confirm.

Object entity ( D2WContext  c  ) 

Returns a fake entity that can be used for tasks such as error/confirm.

Parameters:
c current D2W context
Returns:
dummy entity.

Object entityForControllerName ( D2WContext  c  ) 

Returns the default value for the entity based on the controllerName.

Parameters:
c current D2W context
Returns:
the entity.

Object entityForKey ( D2WContext  c,
String  key 
) [protected]

Object entityForPageConfiguration ( D2WContext  c  ) 

Returns the default value for the entity based on the pageConfiguration.

Parameters:
c current D2W context
Returns:
the entity.

boolean isTaskWithoutEntity ( String  task  )  [protected]

Object smartAttribute ( D2WContext  c  ) 

Resolves the EOAttribute in a smarter manner using the current object from the context as well as the propertyKey to determine the current attribute. Works even with inheirtance. Works around the following problem: An entity A has a relationship b to an entity B, which has a subentity B1. B1 has an attribute k, which B does not have. If in an inspect page for entity A, you use b.k as a display key, then the D2W rules which are based on d2wContext.attribute will not fire properly. This is because attribute is null, instead of containing <EOAttribute entity="B1" name="k">. The reason D2W does not find it is that it uses the Model to find out the EOAttribute and starts from A. Following the relationship b, gives a B, and asking B for an attribute named k returns nil and you lose.

Parameters:
c current D2W context
Returns:
attribute for the current propertyKey object combination.

Object smartDefaultAttributeWidth ( D2WContext  c  ) 

int smartDefaultAttributeWidthAsInt ( D2WContext  c  )  [protected]

Object smartDefaultRows ( D2WContext  c  ) 

Object smartRelationship ( D2WContext  c  ) 

Resolves the EORelationship in a smarter manner using the current object from the context as well as the propertyKey to determine the current relationship. Works even with inheritance. Works around the following problem: An entity A has a relationship b to an entity B, which has a subentity B1. B1 has a relationship k, which B does not have. If in an inspect page for entity A, you use b.k as a display key, then the D2W rules which are based on d2wContext.relationship will not fire properly. This is because relationship is null, instead of containing <EORelationship entity="B1" name="k">. The reason D2W does not find it is that it uses the Model to find out the EORelationship and starts from A. Following the relationship b, gives a B, and asking B for a relationship named k returns null and you lose.

Parameters:
c current D2W context
Returns:
relationship for the current propertyKey object combination.

Object sortKeyForList ( D2WContext  context  ) 

Called when firing this assignment with the key-path: sortKeyForList.

Returns:
the current propertyKey + "." + the current value for keyWhenRelationship.
