Description

Interface Summary

Constraint	A marker interface serving as the supertype of all constraints, whether for entities or for events, or for any other set of objects someone may choose to add in future.
EntityConstraint	Constraints define a set of entities.
EventConstraint	Constraints define a set of events.

Class Summary

AndEntityConstraint	AndEntityConstraint matches all entities that match both of the EntityConstraints given to it in its constructor.
AndEventConstraint	AndEventConstraint matches all events that match both of the EventConstraints given to it in its constructor.
AttributeExistsConstraint	Filter out Entities that have an attribute which satisifies a given EntityConstraint.
AttributeNameContainsConstraint	Selects for Entities which have attributes of a specified name which contain a specified string.
AttributeNameEqualsConstraint	Selects for Entities which have attributes of a specified name which equal a specified string.
AttributeStringMatchConstraint	Selects for Entities which have attributes of a specified name which match a specified string.
BaseExistsConstraint	Filter out Entities that have a base which satisifies a given EntityConstraint.
DateValueRangeConstraint	Matches a DateEntityValue with a range described by two Date.
EntityEqualsConstraint	Check to see if a given Entity is equal to another.
EventContainsEntityConstraint	This EventConstraint describes a subset of Entity-containing events that are described by a given EntityConstraint.
EventTypeIsConstraint	Checks to see if the type of a DataManagerEvent is valid or not.
NameContainsConstraint	Check to see if the name of an Entity contains a given String.
NameEqualsConstraint	Check the name of an Entity.
NameEqualsIgnoringCaseConstraint	Check the name of an Entity and ignore case.
NotEntityConstraint	Logical Not for EntityConstraints.
NotEventConstraint	Logical Not for EventConstraints.
OrEntityConstraint	OrEntityConstraint takes two EntityConstraints in its constructor.
OrEventConstraint	OrEventConstraint takes two EventConstraints in its constructor.
RecursiveOrEntityConstraint	Selects entities out of the Pool whose Attribute Entities may satisfy the constraint as well.
StringValueContainsConstraint	Matches a StringEntityValue with any given String.
StringValueMatchesConstraint	Matches a StringEntityValue with a given regular expression.
ValueClassIsConstraint	Check to see if the class type of an Entity's value is the same, or a subtype, of a specified class.
ValueEqualsConstraint	Check whether the value of an Entity is the same as a given value.
ValueInRangeConstraint	See if the value of an Entity is within a specific range.

Package org.datamanager.constraint Description

Provides the interfaces and classes for Constraints. Constraints are an extremely flexible mechanism for filtering Entities and Events.
