public class ConstraintCollection

extends ArrayList

implements Constraint

Implements a collection of constraints that can be added to any ASN1Type. This class is used by the ASN1AbstractType in order to manage multiple constraints. It inherits from ArrayList and simply calls constrain on all objects contained in it upon a call to its own constrain method.

Constructor Detail

ConstraintCollection

public ConstraintCollection()

ConstraintCollection

public ConstraintCollection(int capacity)

Creates an instance that is initialized with the given capacity.

Parameters:

capacity - The initial capacity of this List.

Method Detail

constrain

public void constrain(ASN1Type o)
               throws ConstraintException

Calls constrain on all objects contained in this list. It is the responsibility of the user to assure that only objects that implement the Constraint interface are added to this constraint collection. Non-adherence will cause a ClassCastException being thrown.

Specified by:

constrain in interface Constraint

Parameters:

o - The caller of the method. This reference is passed to all subordinate constraints.

Throws:

ConstraintException -

addConstraint

public void addConstraint(Constraint o)

Adds a Constraint to this list.

Parameters:

o - The Constraint to add.
