      com.novell.nds.dirxml.driver.xds.RangeConstraint

public final class RangeConstraint

extends Constraint

A constraint that defines the possible range of values for a Parameter. Ranges are inclusive, meaning the boundary values are included in the range.

e.g., [1...100]

Field Summary

static RangeConstraint	NEGATIVE Numbers < 0.
static RangeConstraint	NON_NEGATIVE Numbers >= 0
static RangeConstraint	POSITIVE Numbers > 0.

Constructor Detail

RangeConstraint

public RangeConstraint(char first,
                       char last)

Creates a new character range constraint.

e.g. ['a'...'z']

Parameters:

first - the first character in the range

last - the last character in the range

RangeConstraint

public RangeConstraint(char firstAndLast)

Creates a new RangeConstraint object.

Parameters:

firstAndLast - the first and last character of the range

RangeConstraint

public RangeConstraint(long first,
                       long last)

Creates a new numeric range constraint.

e.g. [1...100]

Parameters:

first - the first number in the range

last - the last number in the range

RangeConstraint

public RangeConstraint(long firstAndLast)

Creates a new RangeConstraint object.

Parameters:

firstAndLast - the first and last number of the range

RangeConstraint

public RangeConstraint(double first,
                       double last)

Creates a new numeric range constraint.

e.g. [1.1...100.1]

Parameters:

first - the first number in the range

last - the last number in the range

RangeConstraint

public RangeConstraint(double firstAndLast)

Creates a new RangeConstraint object.

Parameters:

firstAndLast - the first and last number of the range

RangeConstraint

public RangeConstraint(long someNumber,
                       EqualityOp someOp)

Creates a new numeric range constraint.

e.g. [1...n] or [n...1]

Parameters:

someNumber - the lower or upper bound of the range

someOp - the equality operator (e.g. >,<,>=,<=); must not be null

RangeConstraint

public RangeConstraint(double someNumber,
                       EqualityOp someOp)

Creates a new numeric range constraint.

e.g. [1...n] or [n...1]

Parameters:

someNumber - the lower or upper bound of the range

someOp - the equality operator (e.g. >,<,>=,<=); must not be null

Method Detail

setNOT

public void setNOT()

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
