Constructor Detail

CompoundConstraint

public CompoundConstraint()

Constructs a compound constraint with no initial members. It is expected the client will call "add" to add individual constraints.

CompoundConstraint

public CompoundConstraint(Constraint constraint1,
                          Constraint constraint2)

Creates a CompoundUnaryPredicate composed of two constraints.

Parameters:

constraint1 - the first constraint

constraint2 - the second constraint

CompoundConstraint

public CompoundConstraint(Constraint[] constraints)

Creates a CompoundUnaryPredicate composed of the specified constraints.

Parameters:

constraints - the aggregated constraints

Method Detail

add

public CompoundConstraint add(Constraint constraint)

Add the specified constraint to the set of constraints aggregated by this compound constraint.

Parameters:

constraint - the constraint to add

Returns:

A reference to this, to support chaining.

addAll

public CompoundConstraint addAll(List constraints)

Add the list of constraints to the set of constraints aggregated by this compound constraint.

Parameters:

constraints - the list of constraints to add

Returns:

A reference to this, to support chaining.

remove

public void remove(Constraint constraint)

indexOf

public int indexOf(Constraint child)

get

public Constraint get(int index)

copyInto

public void copyInto(CompoundConstraint p)

set

public void set(int index,
                Constraint constraint)

iterator

public Iterator iterator()

Return an iterator over the aggregated constraints.

Returns:

An iterator

size

public int size()

Returns the number of constraints aggregated by this compound constraint.

Returns:

The size.

test

public abstract boolean test(Object argument)

Description copied from interface: Constraint

Test the provided argument against this predicate's condition.

Parameters:

argument - the argument value

Returns:

true if the condition was satisfied, false otherwise

validateTypeSafety

public void validateTypeSafety(Class constraintType)

toString

public String toString()

Overrides:

toString in class Object
