Method Detail

touch

boolean touch()

Update the last access time of an object.

Returns:

true if object was touched else false

migrate

void migrate(String host,
           int port,
           int database)

Transfer an object from source Redis instance to destination Redis instance

Parameters:

host - - destination host

port - - destination port

database - - destination database

move

boolean move(int database)

Move object to another database

Parameters:

database - - Redis database number

Returns:

true if key was moved else false

getName

String getName()

Returns name of object

Returns:

name - name of object

delete

boolean delete()

Deletes the object

Returns:

true if it was exist and deleted else false

unlink

boolean unlink()

Delete the objects. Actual removal will happen later asynchronously.

Requires Redis 4.0+

Returns:

true if it was exist and deleted else false

rename

void rename(String newName)

Rename current object key to newName

Parameters:

newName - - new name of object

renamenx

boolean renamenx(String newName)

Rename current object key to newName only if new key is not exists

Parameters:

newName - - new name of object

Returns:

true if object has been renamed successfully and false otherwise

isExists

boolean isExists()

Check object existence

Returns:

true if object exists and false otherwise

getCodec

Codec getCodec()

Returns the underlying Codec used by this RObject

Returns:

Codec of object
