Constructor Details

GroupedMinMaxByNState

public GroupedMinMaxByNState(LongFunction<TypedKeyValueHeap> heapFactory)

Method Details

setGroupId

public final void setGroupId(int groupId)

Specified by:

setGroupId in interface GroupedAccumulatorState

ensureCapacity

public final void ensureCapacity(int 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: MinMaxByNState

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

Specified by:

initialize in interface MinMaxByNState

add

public final void add(ValueBlock keyBlock,
 int keyPosition,
 ValueBlock valueBlock,
 int valuePosition)

Description copied from interface: MinMaxByNState

Adds the value to this state.

Specified by:

add in interface MinMaxByNState

popAll

public final void popAll(BlockBuilder out)

Description copied from interface: MinMaxByNState

Writes all values to the supplied block builder as an array entry. After this method is called, the current state will be empty.

Specified by:

popAll in interface MinMaxByNState

merge

public final void merge(MinMaxByNState other)

Description copied from interface: MinMaxByNState

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 MinMaxByNState

serialize

public final void serialize(BlockBuilder out)

Description copied from interface: MinMaxByNState

Write this state to the specified block builder.

Specified by:

serialize in interface MinMaxByNState
