Method Details

tryInit

boolean tryInit(long value,
 long allocationSize)

Initializes Id generator params.

Parameters:

value - - initial value

allocationSize - - values range allocation size

Returns:

true if Id generator initialized false if Id generator already initialized

nextId

long nextId()

Returns next unique number but not monotonically increased

Returns:

number
