Class PropertyConstraint.ByAnnotationType
- All Implemented Interfaces:
PropertyConstraint
- Enclosing interface:
PropertyConstraint
ByAnnotationType
accepts a property value if it
belongs to type defined by AnnotationType.
If you had an Embl AnnotationType then you could say that the REF property must contain annotations that fits your reference AnnotationType (with author list, title, optinal medline ID etc.).
If you wish to build a tree of Annotations so that a property in one is guaranteed to be itself an Annotation of a particular type. Effectively this lets you build your own type system using AnnotationType and PropertyConstraint.- Since:

getAnnotationType
Get the AnnotationType used as a constraint.- Returns:
- the AnnotationType constraint

accept
Description copied from interface:PropertyConstraint
accept
returns true if the value fulfills the constraint. Manually compare items with the PropertyConstraint. Node: this will ususaly be done for you in an AnnotationType instance Use for implementing accept() on AnnotatoinType- Specified by:
accept
in interfacePropertyConstraint
- Parameters:
value
- anObject
to check.- Returns:
- a
boolean
.

subConstraintOf
Description copied from interface:PropertyConstraint
subConstraintOf
returns true if the constraint is a sub-constraint.A pair of constraints super and sub are in a superConstraint/subConstraint relationship if every object accepted by sub is also accepted by super. To put it another way, if instanceOf was used as a set-membership indicator function over some set of objects, then the set produced by super would be a superset of that produced by sub.
It is not expected that constraints will neccesarily maintain references to super/sub types. It will be more usual to infer this relationship by introspecting the constraints themselves. For example,
Useful when attempting to compare two constraints to see if it is necisary to retain both. You may want to check the more general or the more specific constraint only.PropertyConstraint.ByClass
will infer subConstraintOf by looking at the possible class of all items matching subConstraint.- Specified by:
