类 PooledLoThreadLocalOptimizer

  • 所有已实现的接口:
    Optimizer
    public class PooledLoThreadLocalOptimizer
extends AbstractOptimizer
    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.

      • PooledLoThreadLocalOptimizer

        public PooledLoThreadLocalOptimizer​(Class returnClass,
                                    int incrementSize)
        Constructs a PooledLoThreadLocalOptimizer.
        参数:
        returnClass - The Java type of the values to be generated
        incrementSize - The increment size.

      • generate

        public Serializable generate​(AccessCallback callback)
        从接口复制的说明: 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.
        参数:
        callback - Callback to access the underlying value source.
        返回:
        The generated identifier value.

      • getLastSourceValue

        public IntegralDataTypeHolder getLastSourceValue()
        从接口复制的说明: 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.
        返回:
        The last value we obtained from the underlying source; null indicates we have not yet consulted with the source.

      • applyIncrementSizeToSourceValues

        public boolean applyIncrementSizeToSourceValues()
        从接口复制的说明: Optimizer
        Are increments to be applied to the values stored in the underlying value source?
        返回:
        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.
