A collection that has constraints on its names and/or entities.

Method	nameConstraint	A method that determines whether an entity may be added to me with a given name.
Method	entityConstraint	A method that determines whether an entity may be added to me.
Method	reallyPutEntity	Undocumented
Method	putEntity	Store an entity if it meets both constraints.

Inherited from Collection:

Method	__init__	Initialize me.
Method	getStaticEntity	Get an entity that was added to me using putEntity.
Method	getDynamicEntity	Subclass this to generate an entity on demand.
Method	getEntity	Retrieve an entity from me.
Method	delEntity	Remove a static reference for 'name'.
Method	storeEntity	Store an entity for 'name', based on the content of 'request'.
Method	removeEntity	Remove an entity for 'name', based on the content of 'request'.
Method	listStaticEntities	Retrieve a list of all name, entity pairs that I store references to.
Method	listDynamicEntities	A list of all name, entity that I can generate on demand.
Method	listEntities	Retrieve a list of all name, entity pairs I contain.
Method	listStaticNames	Retrieve a list of the names of entities that I store references to.
Method	listDynamicNames	Retrieve a list of the names of entities that I store references to.
Method	listNames	Retrieve a list of all names for entities that I contain.

def nameConstraint(self, name):

A method that determines whether an entity may be added to me with a given name.

If the constraint is satisfied, return 1; if the constraint is not satisfied, either return 0 or raise a descriptive ConstraintViolation.

def entityConstraint(self, entity):

A method that determines whether an entity may be added to me.

If the constraint is satisfied, return 1; if the constraint is not satisfied, either return 0 or raise a descriptive ConstraintViolation.

def reallyPutEntity(self, name, entity):

Undocumented

def putEntity(self, name, entity):

Store an entity if it meets both constraints.

Otherwise raise a ConstraintViolation.
