Constructor & Destructor Documentation

ERXEntityFKConstraintOrder

(

EOModelGroup

modelGroup

)

Designated constructor for implementing classes.

Parameters:

modelGroup

EOModelGroup to get list of all entities from

ERXEntityFKConstraintOrder

(

)

Convenience constructor for implementing classes. Uses EOModelGroup.defaultGroup().

Member Function Documentation

NSDictionary dependenciesByEntity

(

)

[protected, virtual]

Processes the list of entities, creating the ordering dictionary based on foreign key constraints.

Returns:

a dictionary keyed on dependencyKeyFor(EOEntity)

Implements ERXEntityOrder.

String dependencyKeyFor

(

EOEntity

entity

)

[protected]

This implementation returns entity.externalName() as the dependcy is actually on tables not EOEntities

Parameters:

entity

EOEntity to return key into dependency dictionary for

Returns:

key for entity into dependency dictionary returned by dependenciesByEntity()

Reimplemented from ERXEntityOrder.

NSMutableSet entitiesDependentOn	(	NSMutableDictionary	dependencies,
		EOEntity	entity
	)			[protected]

Returns the list of the names of the entities that reference (depend on) this entity. This list is populated by builddependencyList(). If builddependencyList() has not finished executing, the list returned by this method may not be complete.

Parameters:

	dependencies	list of dependencies being built by builddependencyList()
	entity	EOEntity to return list of referencing entities for

Returns:

list of names of entities previously recorded as referencing this entity

boolean hasForeignKeyConstraint

(

EORelationship

relationship

)

[protected]

Parameters:

relationship

EORelationship to test

Returns:

true if relationship models a relation that will have a foreign key constraint in the database
