Enum IdValidation

java.lang.Object
  java.lang.Enum<IdValidation>
      org.eclipse.persistence.annotations.IdValidation

All Implemented Interfaces:

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

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

The IdValidation enum determines the type value that are valid for an Id. By default null is not allowed, and 0 is not allow for singleton ids of long or int type. The default value is ZERO for singleton ids, and NULL for composite ids. This can only be currently set through the ClassDescriptor.setIdValidation() API using a DescriptorCustomizer.

Method Detail

values

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

Returns:

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

valueOf

public static IdValidation 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
