Enum Constant Detail

NO

public static final Multiplicity NO
no expr: expr contains no elements. The 'no' multiplicity can only be used in a multiplicity formula.


LONE

public static final Multiplicity LONE
lone expr: expr contains at most one element.


ONE

public static final Multiplicity ONE
one expr: expr contains exactly one element.


SOME

public static final Multiplicity SOME
some expr: expr contains at least one element.


SET

public static final Multiplicity SET
v: set expr: v is a subset of expr. The 'set' multiplicity can only be used in a declaration.

Method Detail

values

public static final Multiplicity[] 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(Multiplicity c : Multiplicity.values())
        System.out.println(c);

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

valueOf

public static Multiplicity 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
