      com.novell.nds.dirxml.driver.xds.TypedEnumConstraint

public final class TypedEnumConstraint

extends Constraint

A constraint that lists the possible set of typed values for a Parameter. To avoid ClassCastExceptions, be sure the passed comparator can handle the passed type. For example DataType.STRING constraints will pass java.lang.Strings to the passed comparator.

e.g. ['true', 't', 'yes', 'y', '1']

Constructor Summary

TypedEnumConstraint(DataType someType, Comparator someComparator)
Creates a new enumerative constraint instance.

void	add(Collection values) Adds multiple members to this constraint.
void	add(Object value) Adds a single member to this constraint.
boolean	canBeAppliedToMultipleParams() Can this constraint be applied to multiple Parameters?
boolean	equals(Object o) Is the passed constraint equal to this constraint?
boolean	forScalar() Can this constrait be applied to a scalar Parameter?
boolean	forStructured() Can this constraint be applied to a structured Parameter?
int	hashCode() Returns this constraint's hashcode.

Constructor Detail

TypedEnumConstraint

public TypedEnumConstraint(DataType someType,
                           Comparator someComparator)

Creates a new enumerative constraint instance.

Parameters:

someType - must not be null

someComparator - may be null

Method Detail

setNOT

public void setNOT()

Negates this constraint.

add

public void add(Object value)

Adds a single member to this constraint.

Parameters:

value - must not be null

Throws:

IllegalArgumentException - if someValue is null

add

public void add(Collection values)

Adds multiple members to this constraint.

Parameters:

values - must not be null

hashCode

public int hashCode()

Returns this constraint's hashcode.

Returns:

the hashcode

equals

public boolean equals(Object o)

Is the passed constraint equal to this constraint?

Parameters:

o - may be null

Returns:

true if they're equal; false if they're not

forStructured

public boolean forStructured()

Description copied from class: Constraint

Can this constraint be applied to a structured Parameter?

A structured Parameter consists of multiple primitives or other structured Parameters.

Specified by:

forStructured in class Constraint

Returns:

true if it can; false if it can't

forScalar

public boolean forScalar()

Description copied from class: Constraint

Can this constrait be applied to a scalar Parameter?

A scalar Parmeter is a primitive (e.g., long, int, boolean) that has a single value.

Specified by:

forScalar in class Constraint

Returns:

true if it can; false if it can't

canBeAppliedToMultipleParams

public boolean canBeAppliedToMultipleParams()

Description copied from class: Constraint

Can this constraint be applied to multiple Parameters?

Specified by:

canBeAppliedToMultipleParams in class Constraint

Returns:

true if it can; false if it can't
