java.lang.Object

java.lang.Enum<EdmOnDelete>

org.apache.olingo.commons.api.edm.constants.EdmOnDelete

All Implemented Interfaces:

Enum Constants

Enum Constant and Description
Cascade Cascade, meaning the related entities will be deleted if the source entity is deleted
None None, meaning a DELETE request on a source entity with related entities will fail,
SetDefault SetDefault, meaning all properties of related entities that are tied to properties of the source entity via a referential constraint and that do not participate in other referential constraints will be set to their default value.
SetNull SetNull, meaning all properties of related entities that are tied to properties of the source entity via a referential constraint and that do not participate in other referential constraints will be set to null,

Enum Constant Detail

Cascade

public static final EdmOnDelete Cascade

Cascade, meaning the related entities will be deleted if the source entity is deleted

None

public static final EdmOnDelete None

None, meaning a DELETE request on a source entity with related entities will fail,

SetNull

public static final EdmOnDelete SetNull

SetNull, meaning all properties of related entities that are tied to properties of the source entity via a referential constraint and that do not participate in other referential constraints will be set to null,

Method Detail

values

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

Returns:

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

valueOf

public static EdmOnDelete 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
