    • Constructor Detail

      • PooledOptimizer

        public PooledOptimizer​(java.lang.Class returnClass,
                               int incrementSize)
        Constructs a PooledOptimizer
        returnClass - The Java type of the values to be generated
        incrementSize - The increment size.
    • Method Detail

      • generate

        public 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.
        Specified by:
        generate in interface Optimizer
        callback - Callback to access the underlying value source.
        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.
        Specified by:
        getLastSourceValue in interface Optimizer
        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?
        Specified by:
        applyIncrementSizeToSourceValues in interface Optimizer
        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 IntegralDataTypeHolder getLastValue()
        Getter for property 'lastValue'.

        Exposure intended for testing purposes.

        Value for property 'lastValue'.
      • injectInitialValue

        public void injectInitialValue​(long initialValue)
        Description copied from interface: InitialValueAwareOptimizer
        Reports the user specified initial value to the optimizer.

        -1 is used to indicate that the user did not specify.

        Specified by:
        injectInitialValue in interface InitialValueAwareOptimizer
        initialValue - The initial value specified by the user, or -1 to indicate that the user did not specify.
