Enum Cardinality

java.lang.Object
  java.lang.Enum<Cardinality>
      org.qtitools.qti.value.Cardinality

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Cardinality>

public enum Cardinality
extends java.lang.Enum<Cardinality>

This class describes cardinality of value. Supported cardinalities are:

single - one value

multiple - unordered list of values of same type

ordered - ordered list of values of same type

record - unordered list of values of different types

Method Detail

values

public static final Cardinality[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(Cardinality c : Cardinality.values())
        System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they're declared

valueOf

public static Cardinality valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

isSingle

public boolean isSingle()

Returns true if this cardinality is single; false otherwise.

Returns:

true if this cardinality is single; false otherwise

isList

public boolean isList()

Returns true if this cardinality is multiple or ordered; false otherwise.

Returns:

true if this cardinality is multiple or ordered; false otherwise

isMultiple

public boolean isMultiple()

Returns true if this cardinality is multiple; false otherwise.

Returns:

true if this cardinality is multiple; false otherwise

isOrdered

public boolean isOrdered()

Returns true if this cardinality is ordered; false otherwise.

Returns:

true if this cardinality is ordered; false otherwise

isRecord

public boolean isRecord()

Returns true if this cardinality is record; false otherwise.

Returns:

true if this cardinality is record; false otherwise

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<Cardinality>

parseCardinality

public static Cardinality parseCardinality(java.lang.String cardinality)
                                    throws QTIParseException

Returns parsed Cardinality from given String.

Parameters:

cardinality - String representation of Cardinality

Returns:

parsed Cardinality from given String

Throws:

QTIParseException - if given String is not valid Cardinality

intersection

public static Cardinality[] intersection(Cardinality[] firstSet,
                                         Cardinality[] secondSet)

Returns intersection of two given cardinalities sets (order is not important).

Parameters:

firstSet - first set of cardinalities

secondSet - second set of cardinalities

Returns:

intersection of two given cardinalities sets
