Enum RelationshipEndCardinality

java.lang.Object

java.lang.Enum<RelationshipEndCardinality>

org.odpi.openmetadata.repositoryservices.connectors.stores.metadatacollectionstore.properties.typedefs.RelationshipEndCardinality

All Implemented Interfaces:

Serializable, Comparable<RelationshipEndCardinality>

public enum RelationshipEndCardinality
extends Enum<RelationshipEndCardinality>
implements Serializable

RelationshipCardinality is used in a RelationshipEndDef to indicate how many relationships of this type can be connected to an entity instance.:

• UNKNOWN: uninitialized cardinality
• AT_MOST_ONE: means there can be zero or one instances of this relationship connected to an instance of the EntityDef. This relationship is written as 0..1 in UML.
• ANY_NUMBER: means there can be none, one or many instances of this relationship connected to an instance of the EntityDef. This relationship is often written as 0..* or * in UML.

Method Detail

values

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

Returns:

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

valueOf

public static RelationshipEndCardinality 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

getOrdinal

public int getOrdinal()

Return the numeric representation of the cardinality.

Returns:

int ordinal

getName

public String getName()

Return the default name of the cardinality.

Returns:

String name

getDescription

public String getDescription()

Return the default description of the cardinality.

Returns:

String description

toString

public String toString()

toString() JSON-style

Overrides:

toString in class Enum<RelationshipEndCardinality>

Returns:

string description
