Method Detail

• generate

  Serializable generate(AccessCallback callback)

  Generate an identifier value accounting for this specific optimization.

  Parameters:

  callback - Callback to access the underlying value source.

  Returns:

  The generated identifier value.

• getLastSourceValue

  IntegralDataTypeHolder getLastSourceValue()

  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.

• getIncrementSize

  int getIncrementSize()

  Retrieves the defined increment size.

  Returns:

  The increment size.

• applyIncrementSizeToSourceValues

  boolean applyIncrementSizeToSourceValues()

  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.
