Constructor Detail

MultiRequiredConstraint

public MultiRequiredConstraint()

Creates a new required constraint instance.

Method Detail

setOperator

public void setOperator(LogicalOp someOp)

Changes this constraint's grouping operator to someOp.

e.g. (['true', 't', 'yes', 'y'] or [1])
e.g. (['true', 't', 'yes', 'y'] and [1])

Parameters:

someOp - is ignored when 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
