Method Detail
-
isValid
public abstract boolean isValid(Link link, ResourceContext context)
Returns true if the specified link satisfies the constraint.- Parameters:
link
- link to be validatedcontext
- resource context for checking available resources- Returns:
- true if link is viable
-
cost
public double cost(Link link, ResourceContext context)
Evaluates the specified link and provides the cost for its traversal. Negative return value means the specified link does not satisfy this constraint.- Specified by:
cost
in interfaceConstraint
- Parameters:
link
- link to be evaluatedcontext
- resource context for validating availability of resources- Returns:
- cost of link traversal
-
validate
public boolean validate(Path path, ResourceContext context)
Description copied from interface:Constraint
Validates that the specified path satisfies the constraint.- Specified by:
validate
in interfaceConstraint
- Parameters:
path
- path to be validatedcontext
- resource context for validating availability of resources- Returns:
- cost of link traversal
