java.lang.Object
- java.lang.Enum<OccurrenceIndicator>
- - net.sf.saxon.s9api.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.

```
public static OccurrenceIndicator[] values()
```
    Returns an array containing the constants of this enum type, in the order they are 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 are 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
    
    java.lang.NullPointerException - if the argument is null

  - 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
