All Implemented Interfaces:

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

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

Represents one of the possible occurrence indicators in a SequenceType. The four standard values are ONE (no occurrence indicator), ZERO_OR_ONE (?), ZERO_OR_MORE (*), ONE_OR_MORE (+). In addition the value ZERO is supported, this is used only in the type empty-sequence() which matches an empty sequence and nothing else.

Method Detail

values

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

Returns:

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

valueOf

public static OccurrenceIndicator 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

getCardinality

protected int getCardinality()

getOccurrenceIndicator

protected static OccurrenceIndicator getOccurrenceIndicator(int cardinality)

subsumes

public boolean subsumes(OccurrenceIndicator other)

Determine whether one occurrence indicator subsumes another. Specifically, A.subsumes(B) is true if every sequence that satisfies the occurrence indicator B also satisfies the occurrence indicator A.

Parameters:

other - The other occurrence indicator

Returns:

true if this occurrence indicator subsumes the other occurrence indicator
