public void setBucketCapacity(int capacity)

Description copied from interface: ChunkedUpdateByOperator

Notify the operator of the current maximum bucket.

Specified by:

setBucketCapacity in interface ChunkedUpdateByOperator

Overrides:

setBucketCapacity in class AbstractStaticUpdateByOperator

Parameters:

capacity - the capacity

getInputColumnName

@NotNull public String getInputColumnName()

Description copied from interface: ChunkedUpdateByOperator

Get the name of the input column this operator depends on.

Returns:

the name of the input column

getOutputColumnNames

@NotNull public String[] getOutputColumnNames()

Description copied from interface: ChunkedUpdateByOperator

Get an array of the output column names.

Returns:

the output column names.

getOutputColumns

@NotNull public Map<String,ColumnSource<?>> getOutputColumns()

Description copied from interface: ChunkedUpdateByOperator

Get a map of outputName to output ColumnSource for this operation.

Returns:

a map of output column name to output column source

makeUpdateContext

@NotNull public ChunkedUpdateByOperator.UpdateContext makeUpdateContext(int chunkSize)

Description copied from interface: ChunkedUpdateByOperator

Make an ChunkedUpdateByOperator.UpdateContext suitable for use with non-bucketed updates.

Parameters:

chunkSize - The expected size of chunks that will be provided during the update,

initializeFor

public void initializeFor(@NotNull ChunkedUpdateByOperator.UpdateContext updateContext, @NotNull UpdateBy.UpdateType type, @NotNull ReadOnlyIndex updateIndex)

Description copied from interface: ChunkedUpdateByOperator

Initialize the context for the specified stage of the update process. This will always be followed by a call to ChunkedUpdateByOperator.finishFor(UpdateContext, UpdateBy.UpdateType) at the end of each successful update.

Specified by:

initializeFor in interface ChunkedUpdateByOperator

Overrides:

initializeFor in class AbstractStaticUpdateByOperator

Parameters:

updateContext - the context object

type - the type of update being applied

updateIndex - the index of rows associated with the update.
