- All Implemented Interfaces:
Optimizer
Variation of
PooledOptimizer
which interprets the incoming database
value as the lo value, rather than the hi value, as well as using thread local
to cache the generation state.- See Also:

Method Details

generate
Description copied from interface:Optimizer
Generate an identifier value accounting for this specific optimization. All known implementors are synchronized. Consider carefully if a new implementation could drop this requirement.- Parameters:
callback
- Callback to access the underlying value source.- Returns:
- The generated identifier value.
-
getLastSourceValue
Description copied from interface:Optimizer
A common means to access the last value obtained from the underlying source. This is intended for testing purposes, since accessing the underlying database source directly is much more difficult.- Returns:
- The last value we obtained from the underlying source; null indicates we have not yet consulted with the source.
-
applyIncrementSizeToSourceValues
public boolean applyIncrementSizeToSourceValues()Description copied from interface:Optimizer
Are increments to be applied to the values stored in the underlying value source?- Returns:
- True if the values in the source are to be incremented according to the defined increment size; false otherwise, in which case the increment is totally an in memory construct.
