Method Detail

getCardinality

public Cardinality getCardinality()

Description copied from interface: Value

Returns cardinality of this value.

If value is NULL returns null.

true if this container is ordered; false otherwise

contains

public boolean contains(OrderedValue orderedValue)

Returns true if this container contains given OrderedValue; false otherwise.

Parameters:

orderedValue - given OrderedValue

Returns:

true if this container contains given OrderedValue; false otherwise

add

public boolean add(OrderedValue value)
            throws QTIBaseTypeException

Adds OrderedValue into this container.

Takes all values from OrderedValue container and adds them into this container.

Ordered container can contain only values of the same BaseType.

NULL OrderedValue container is ignored.

Parameters:

value - added OrderedValue

Returns:

true if value was added; false otherwise
