Class NoOpConstraint

java.lang.Object
io.fluxzero.common.api.search.NoOpConstraint
All Implemented Interfaces:
Constraint
public class NoOpConstraint extends Object implements Constraint
A Constraint implementation that matches all documents and imposes no filtering conditions.

This is typically used as a placeholder or default when no real constraint is needed. It always returns true for matches(Document) and is considered to have no path constraints.

This constraint is used internally by various factory methods (such as those in MatchConstraint, FacetConstraint, etc.) when an input is null, empty, or otherwise does not yield a meaningful constraint.

For example, MatchConstraint.match(null) returns a NoOpConstraint.
