INITIAL_ADDED_COUNT

protected static final BigDecimal INITIAL_ADDED_COUNT

DEFAULT_ADD_SIZE

protected static final BigDecimal DEFAULT_ADD_SIZE

_resultType

protected final Class<?> _resultType

The result type of sequence next value. (NotNull)

_cacheSize

protected final BigDecimal _cacheSize

The cache size of sequence that is used by increment way only. (NotNull)

_incrementSize

protected final Integer _incrementSize

The increment size of sequence that is used by batch way only. (NullAllowed: If null, it cannot use batch way)

_addedCount

protected volatile BigDecimal _addedCount

The added count. If cached list is valid, this value is unused. (NotNull)

_sequenceValue

protected volatile BigDecimal _sequenceValue

The sequence value as base point. (NullAllowed: only at first null)

_batchFirstValue

protected volatile BigDecimal _batchFirstValue

The sequence value as first value for batch way only. (NullAllowed: at first or not batch way)

_cachedList

protected final List<BigDecimal> _cachedList

_tmpSortedSet

protected final SortedSet<BigDecimal> _tmpSortedSet

_batchWay

protected volatile boolean _batchWay

Is the batch way valid?

_internalDebug

protected boolean _internalDebug

Is the internal debug valid? (should be set when immediately after initialization because of no volatile)
