GroupedMinMaxNState

public GroupedMinMaxNState(LongFunction<TypedHeap> heapFactory,
 Function<Block,TypedHeap> deserializer)

Method Details

setGroupId

public final void setGroupId(long groupId)

Specified by:

setGroupId in interface GroupedAccumulatorState

ensureCapacity

public final void ensureCapacity(long size)

Specified by:

ensureCapacity in interface GroupedAccumulatorState

getEstimatedSize

public final long getEstimatedSize()

Specified by:

getEstimatedSize in interface AccumulatorState

initialize

public final void initialize(long n)

Description copied from interface: MinMaxNState

Initialize the state if not already initialized. Only the first call is processed and all subsequent calls are ignored.

Specified by:

initialize in interface MinMaxNState

add

public final void add(Block block,
 int position)

Description copied from interface: MinMaxNState

Adds the value to this state.

Specified by:

add in interface MinMaxNState

merge

public final void merge(MinMaxNState other)

Description copied from interface: MinMaxNState

Merge with the specified state. The supplied state should not be used after this method is called, because the internal details of the state may be reused in this state.

Specified by:

merge in interface MinMaxNState

writeAll

public final void writeAll(BlockBuilder out)

Description copied from interface: MinMaxNState

Writes all values to the supplied block builder as an array entry.

Specified by:

writeAll in interface MinMaxNState

serialize

public final void serialize(BlockBuilder out)

Description copied from interface: MinMaxNState

Write this state to the specified block builder.

Specified by:

serialize in interface MinMaxNState

deserialize

public final void deserialize(Block rowBlock)

Description copied from interface: MinMaxNState

Read the state to the specified block builder.

Specified by:

deserialize in interface MinMaxNState
