Enum EdmNavigationProperty.Multiplicity
java.lang.Object
java.lang.Enum<EdmNavigationProperty.Multiplicity>
org.apache.olingo.odata2.api.annotation.edm.EdmNavigationProperty.Multiplicity
- All Implemented Interfaces:
- Serializable, Comparable<EdmNavigationProperty.Multiplicity>
- Enclosing class:
- EdmNavigationProperty
public static enum EdmNavigationProperty.Multiplicity
- extends Enum<EdmNavigationProperty.Multiplicity>
EdmMultiplicity indicates the number of entity type instances
an association end can relate to:
- ZERO_OR_ONE (0..1)
- value is exactly one but can be null (i.e.
nullable = true
)
- ONE (1)
- value is exactly one (i.e.
nullable = false
)
- MANY (*)
- many values (which includes zero values (e.g. empty collection))
ZERO_OR_ONE
public static final EdmNavigationProperty.Multiplicity ZERO_OR_ONE
ONE
public static final EdmNavigationProperty.Multiplicity ONE
MANY
public static final EdmNavigationProperty.Multiplicity MANY
values
public static EdmNavigationProperty.Multiplicity[] 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 (EdmNavigationProperty.Multiplicity c : EdmNavigationProperty.Multiplicity.values())
System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in
the order they are declared
valueOf
public static EdmNavigationProperty.Multiplicity valueOf(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:
IllegalArgumentException
- if this enum type has no constant
with the specified name
NullPointerException
- if the argument is null
