Enum Constant Summary

Enum Constants

Enum Constant and Description
BRING_BACK_GENERATED_IDS Bring back any auto-generated id value into the PropertyBox which was subject of a data manipulation operation, if a corresponding Property (using the property name) is available in the box property set.
SAVE_DISABLE_INSERT_FALLBACK By default, the DatastoreOperations.save(DataTarget, PropertyBox, WriteOption...) operation should fallback to an INSERT type operation when the value existence cannot be consistently verified in the persistence source (for example, is the persistence source entity supports a primary key and the primary key cannot be obtained or the primary key values to use are not provided) to determine whether an UPDATE type operation should by performed.

Method Summary

Modifier and Type	Method and Description
static DefaultWriteOption	valueOf(String name) Returns the enum constant of this type with the specified name.
static DefaultWriteOption[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

BRING_BACK_GENERATED_IDS

public static final DefaultWriteOption BRING_BACK_GENERATED_IDS

Bring back any auto-generated id value into the PropertyBox which was subject of a data manipulation operation, if a corresponding Property (using the property name) is available in the box property set.

SAVE_DISABLE_INSERT_FALLBACK

public static final DefaultWriteOption SAVE_DISABLE_INSERT_FALLBACK

By default, the DatastoreOperations.save(DataTarget, PropertyBox, WriteOption...) operation should fallback to an INSERT type operation when the value existence cannot be consistently verified in the persistence source (for example, is the persistence source entity supports a primary key and the primary key cannot be obtained or the primary key values to use are not provided) to determine whether an UPDATE type operation should by performed. This write option disables the default behaviour, forcing to throw an error in such kind of situations.

Method Detail

values

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

Returns:

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

valueOf

public static DefaultWriteOption 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
