Field Details

prevFlusher

protected transient UpdateCommitter<io.deephaven.engine.table.impl.sources.ArraySourceHelper<Long,long[]>> prevFlusher

The presence of a prevFlusher means that this ArraySource wants to track previous values. If prevFlusher is null, the ArraySource does not want (or does not yet want) to track previous values. Deserialized ArraySources never track previous values.

prevAllocated

protected transient gnu.trove.list.array.TIntArrayList prevAllocated

ensurePreviousClockCycle

protected transient long ensurePreviousClockCycle

If ensure previous has been called, we need not check previous values when filling.

Constructor Details

LongArraySource

public LongArraySource()

Method Details

startTrackingPrevValues

public void startTrackingPrevValues()

Force my inheritors to implement this method, rather than taking the interface default.

Specified by:

startTrackingPrevValues in interface ColumnSource<Long>

ensureCapacity

public void ensureCapacity(long capacity,
 boolean nullFill)

Description copied from interface: WritableColumnSource

Ensure that this WritableColumnSource can accept row keys in range [0, capacity).

Specified by:

ensureCapacity in interface WritableColumnSource<Long>

Specified by:

Parameters:

This version of `prepareForParallelPopulation` will internally call ensureCapacity(long, boolean) to make sure there is room for the incoming values.

Specified by:
