Class AllConstraint

java.lang.Object

io.fluxzero.common.api.search.constraints.AllConstraint

All Implemented Interfaces:

Constraint

public class AllConstraint
extends Object
implements Constraint

A composite constraint that requires all inner constraints to match.

This is equivalent to a logical AND operation over the contained constraints. The document must satisfy every inner constraint in the list for the AllConstraint to match.

If the constraint list is empty, this becomes a no-op constraint that matches all documents. If only one constraint is provided, it is returned directly to avoid unnecessary nesting.

• for logical OR
• for logical negation

public AllConstraint()

Method Details

all

public static Constraint all(Constraint... constraints)

Creates an AllConstraint 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 requires all inputs to match

all

public static Constraint all(Collection<Constraint> constraints)

Creates an AllConstraint 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 requires all inputs to match

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
