Method Detail

generate

public 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

public long getLastSourceValue()
A common means to access the last value obtained from the underlying source. This is intended for testing purposes, since accessing the unerlying database source directly is much more difficult.

Returns:
The last value we obtained from the underlying source; -1 indicates we have not yet consulted with the source.

applyIncrementSizeToSourceValues

public 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.

getLastValue

public long getLastValue()
Getter for property 'lastValue'.

Returns:
Value for property 'lastValue'.
