CREATE Existing indexes will not be altered, missing indexes will be created.
MERGE Upon session factory initialization, index mappings will be merged with existing ones, causing an exception if a mapping to be merged is not compatible with the existing one.
NONE Indexes will never be created or deleted.
RECREATE Indexes - and all their contents - will be deleted and newly created upon session factory initialization.
RECREATE_DELETE The same as RECREATE, but indexes - and all their contents - will be deleted upon session factory shut-down as well.

Upon session factory initialization, index mappings will be merged with existing ones, causing an exception if a mapping to be merged is not compatible with the existing one. Missing indexes and mappings will be created.

CREATE

public static final IndexSchemaManagementStrategy CREATE

Existing indexes will not be altered, missing indexes will be created.

RECREATE

public static final IndexSchemaManagementStrategy RECREATE

Indexes - and all their contents - will be deleted and newly created upon session factory initialization.

RECREATE_DELETE

The same as RECREATE, but indexes - and all their contents - will be deleted upon session factory shut-down as well.

Method Detail

values

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

Returns:

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

valueOf

public static IndexSchemaManagementStrategy 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
