Method Detail

generate
public java.io.Serializable generate(AccessCallback callback)
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
public IntegralDataTypeHolder 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.
