nextId

public long nextId()

Description copied from interface: RIdGenerator

Returns next unique number but not monotonically increased

Specified by:

nextId in interface RIdGenerator

Returns:

number

tryInitAsync

public RFuture<Boolean> tryInitAsync(long value,
                                     long allocationSize)

Description copied from interface: RIdGeneratorAsync

Initializes Id generator params.

Specified by:

tryInitAsync in interface RIdGeneratorAsync

Parameters:

value - - initial value

allocationSize - - values range allocation size

Returns:

true if Id generator initialized false if Id generator already initialized

nextIdAsync

public RFuture<Long> nextIdAsync()

Description copied from interface: RIdGeneratorAsync

Returns next unique number but not monotonically increased

Specified by:

nextIdAsync in interface RIdGeneratorAsync

Returns:

number

deleteAsync

public RFuture<Boolean> deleteAsync()

Description copied from interface: RObjectAsync

Delete object in async mode

Specified by:

deleteAsync in interface RObjectAsync

Overrides:

deleteAsync in class RedissonObject

Returns:

true if object was deleted false if not

sizeInMemoryAsync

public RFuture<Long> sizeInMemoryAsync()

Description copied from interface: RObjectAsync

Returns bytes amount used by object in Redis memory.

Specified by:

sizeInMemoryAsync in interface RObjectAsync

Overrides:

sizeInMemoryAsync in class RedissonObject
