Method Details

resetForReprocess

public void resetForReprocess(@NotNull
 UpdateByOperator.UpdateContext context,
 @NotNull
 ReadOnlyIndex sourceIndex,
 @NotNull
 ColumnSource<?> inputSource,
 long firstUnmodifiedKey)

Description copied from interface: UpdateByOperator

Reset the operator to the state at the `firstModifiedKey` for non-bucketed operation. This is invoked immediately prior to calls to UpdateByOperator.reprocessChunk(UpdateContext, OrderedKeys, LongChunk, Chunk, ReadOnlyIndex).

A `firstUnmodifiedKey` of ReadOnlyIndex.NULL_KEY indicates that the entire table needs to be recomputed.

Specified by:

resetForReprocess in interface UpdateByOperator

Overrides:

resetForReprocess in class BaseDoubleUpdateByOperator

Parameters:

context - the context object

sourceIndex - the current index of the source table

inputSource - the most primitive form of the input column source

firstUnmodifiedKey - the first unmodified key after which we will reprocess rows.

resetForReprocess

public void resetForReprocess(@NotNull
 UpdateByOperator.UpdateContext ctx,
 @NotNull
 ReadOnlyIndex bucketIndex,
 @NotNull
 ColumnSource<?> inputSource,
 long bucketPosition,
 long firstUnmodifiedKey)

Description copied from interface: UpdateByOperator

Reset the operator to the state at the `firstModifiedKey` for the specified bucket. This is invoked immediately prior to calls to UpdateByOperator.reprocessChunk(UpdateContext, OrderedKeys, Chunk, LongChunk, IntChunk, IntChunk, IntChunk).

Specified by:

resetForReprocess in interface UpdateByOperator

Overrides:

resetForReprocess in class BaseDoubleUpdateByOperator

Parameters:

ctx - the context object

bucketIndex - the current index of the specified bucket

inputSource - the most primitive form of the input column source

firstUnmodifiedKey - the first unmodified key in the bucket after which we will reprocess rows.

addChunk

public void addChunk(@NotNull
 UpdateByOperator.UpdateContext context,
 @NotNull
 Chunk<Attributes.Values> values,
 @NotNull
 LongChunk<? extends Attributes.KeyIndices> keyChunk,
 @NotNull
 IntChunk<Attributes.KeyIndices> bucketPositions,
 @NotNull
 IntChunk<Attributes.ChunkPositions> startPositions,
 @NotNull
 IntChunk<Attributes.ChunkLengths> runLengths)

Description copied from interface: UpdateByOperator

Add a chunk of bucketed items to the operation.

Parameters:

context - the context object

values - the value chunk

keyChunk - a chunk of keys for the rows being added

bucketPositions - a chunk of hash bucket positions for each key

startPositions - the start position of a run within the chunk

runLengths - the runLengths of each run of bucket values

doAddChunk

protected void doAddChunk(@NotNull
 BaseDoubleUpdateByOperator.Context ctx,
 @NotNull
 OrderedKeys inputKeys,
 @NotNull
 Chunk<Attributes.Values> workingChunk,
 long groupPosition)

Specified by:
