Method Details

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface SafeCloseable

Overrides:

close in class BaseCharUpdateByOperator.Context

setValueChunks

public void setValueChunks(@NotNull
 @NotNull Chunk<? extends Values>[] valueChunks)

Overrides:

setValueChunks in class BaseCharUpdateByOperator.Context

push

public void push(int pos,
 int count)

Description copied from class: UpdateByOperator.Context

Add values to the operators current data set

Specified by:

push in class UpdateByOperator.Context

Parameters:

pos - the index in the associated chunk where this value can be found. Depending on the usage, might be a values chunk (for cumulative operators) or an influencer values chunk (for windowed). It is the task of the operator to pull the data from the chunk and use it properly

count - the number of items to push from the chunk

pop

public void pop(int count)

Description copied from class: UpdateByOperator.Context

Remove values from the operators current data set. This is only valid for windowed operators as cumulative operators only append values

Overrides:

pop in class UpdateByOperator.Context

Parameters:

count - the number of items to pop from the data set

writeToOutputChunk

public void writeToOutputChunk(int outIdx)

Description copied from class: UpdateByOperator.Context

Write the current value for this row to the output chunk

Overrides:

writeToOutputChunk in class BaseCharUpdateByOperator.Context

reset

public void reset()

Description copied from class: UpdateByOperator.Context

Reset the operator data values to a known state. This may occur during initialization or when a windowed operator has an empty window

Overrides:

reset in class BaseCharUpdateByOperator.Context
