Enum Class OccurrenceIndicator
- All Implemented Interfaces:
Serializable
,Comparable<OccurrenceIndicator>
,Constable
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.

values
Returns an array containing the constants of this enum class, in the order they are declared.- Returns:
- an array containing the constants of this enum class, in the order they are declared
-
valueOf
Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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:

subsumes
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
