Class AnyConstraint

java.lang.Object

io.fluxzero.common.api.search.constraints.AnyConstraint

All Implemented Interfaces:

Constraint

public class AnyConstraint
extends Object
implements Constraint

A composite constraint that requires at least one inner constraint to match.

This is equivalent to a logical OR operation over the contained constraints. The document matches if any of the provided constraints evaluate to true.

If the constraint list is empty, a NoOpConstraint is returned (which always matches). If only one constraint is provided, it is returned directly without wrapping in an AnyConstraint.

AnyConstraint

public AnyConstraint()

Method Details

any

public static Constraint any(Constraint... constraints)

Creates an AnyConstraint from the given array of constraints.

If the array is empty, a NoOpConstraint is returned. If only one constraint is provided, that constraint is returned directly.

Parameters:

constraints - one or more constraints to combine

Returns:

a constraint that matches if any input matches

any

public static Constraint any(Collection<Constraint> constraints)

Creates an AnyConstraint from the given collection of constraints.

If the collection is empty, a NoOpConstraint is returned. If it contains only one constraint, that constraint is returned directly.

Parameters:

constraints - a collection of constraints to combine

Returns:

a constraint that matches if any input matches

matches

public boolean matches(Document document)

Description copied from interface: Constraint

Evaluates whether this constraint applies to the given document.

Specified by:

matches in interface Constraint

Parameters:

document - the document to test

Returns:

true if the constraint matches the document

hasPathConstraint

public boolean hasPathConstraint()

Description copied from interface: Constraint

Indicates whether this constraint targets specific paths in the document.

Specified by:

hasPathConstraint in interface Constraint

Returns:

true if path-based filtering is involved
