Field Details

prevFlusher

protected transient UpdateCommitter<LongSparseArraySource> 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.

blocks

protected LongOneOrN.Block0 blocks

prevBlocks

protected transient LongOneOrN.Block0 prevBlocks

public void setNull(long key)

Specified by:

set

public final void set(long key,
 long value)

Specified by:

set in interface WritableSource<Long>

Overrides:

set in class SparseArrayColumnSource<Long>

shift

public void shift(ReadOnlyIndex keysToShift,
 long shiftDelta)

Overrides:

set

public void set(long key,
 Long value)

get

public Long get(long index)

Description copied from interface: ElementSource

Get the value from the source. This may return boxed values for basic types.

Specified by:

get in interface ColumnSourceGetDefaults.ForLong

Specified by:

get in interface ElementSource<Long>

Parameters:

index - the location in index space to get the value from.

Returns:

the value at the index, potentially null.

getPrev

public Long getPrev(long index)

Description copied from interface: ElementSource

Get the previous value at the index. Previous values are used during an LTM update cycle to process changes in data. During normal operation previous values will be identical to current values.

Specified by:

getPrev in interface ElementSource<Long>

Specified by:

getPrev in interface MutableColumnSourceGetDefaults.ForLong

Parameters:

index - the location in index space to get the value from.

Returns:

the previous value at the index, or null.

copy

public void copy(ColumnSource<Long> sourceColumn,
 long sourceKey,
 long destKey)

Specified by:

copy in interface WritableSource<Long>

getLong

public final long getLong(long index)

Description copied from interface: ElementSource

Get the value at the index as a long.

Specified by:

getLong in interface ElementSource<Long>

Parameters:

index - the location in index space to get the value from.

Returns:

the long at the index, null values are represented by QueryConstants.NULL_LONG

getPrevLong

public final long getPrevLong(long index)

Description copied from interface: ElementSource

Get the previous value at the index as a long. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevLong in interface ElementSource<Long>

Parameters:

index - the location in index space to get the previous value from.

Returns:

the previous long at the index, null values are represented by QueryConstants.NULL_LONG

startTrackingPrevValues

public void startTrackingPrevValues()

Description copied from interface: ColumnSource

ColumnSource implementations that track previous values have the option to not actually start tracking previous values until this method is called. This is an option, not an obligation: some simple ColumnSource implementations (like TSingleValueSource for various T) always track previous values; other implementations (like PrevColumnSource) never do; some (like TArrayColumnSource) only start tracking once this method is called. An immutable column source can not have distinct prev values; therefore it is implemented as a no-op.

Specified by:

startTrackingPrevValues in interface ColumnSource<Long>
