All Implemented Interfaces:

Constraint, LegacyConstraint

public class BasicLegacyConstraint

extends BasicConstraint

implements LegacyConstraint

Basic implementation.

This constraint type is provided for the sole purpose of aligning existing legacy code with the new search query framework, and will eventually be phased out.

Constructor Detail

BasicLegacyConstraint

public BasicLegacyConstraint(String constraint)

Constructor.

Parameters:

constraint - The non-null constraint as it appears in the where-clause.

Throws:

IllegalArgumentException - When an invalid argument is supplied.

Method Detail

setConstraint

public BasicLegacyConstraint setConstraint(String constraint)

Sets the constraint.

Parameters:

constraint - The non-null constraint as it appears in the where-clause (may also not be empty string)

Returns:

This BasicLegacyConstraint instance.

Throws:

IllegalArgumentException - When an invalid argument is supplied.

getConstraint

public String getConstraint()

Description copied from interface: LegacyConstraint

Gets the constraint.

Specified by:

getConstraint in interface LegacyConstraint

Returns:

The constraint as it appears in the where-clause.

equals

public boolean equals(Object obj)

Description copied from interface: Constraint

Compares this constraint to the specified object. The result is true if and only if the argument is a non-null Constraint object representing the same constraint(s).

Specified by:

equals in interface Constraint

Overrides:

equals in class BasicConstraint

hashCode

public int hashCode()

Specified by:

hashCode in interface Constraint

Overrides:

hashCode in class BasicConstraint

toString

public String toString()

Description copied from interface: LegacyConstraint

Returns a string representation of this LegacyConstraint. The string representation has the form "LegacyConstraint(inverse:<:inverse>, field:<field>, constraint:<constraint>)" where

• <inverse>is the value returned by isInverse()
• <constraint> is the value returned by getConstraint()

Specified by:

toString in interface LegacyConstraint
