Constructor Detail

ArrayBlock

public ArrayBlock(int positionCount,
                  boolean[] valueIsNull,
                  int[] offsets,
                  Block values)

Method Detail

getPositionCount

public int getPositionCount()

Description copied from interface: Block

Returns the number of positions in this block.

getSizeInBytes

public long getSizeInBytes()

Description copied from interface: Block

Returns the logical size of this block in memory.

getRetainedSizeInBytes

public long getRetainedSizeInBytes()

Description copied from interface: Block

Returns the retained size of this block in memory. This method is called from the inner most execution loop and must be fast.

retainedBytesForEachPart

public void retainedBytesForEachPart(java.util.function.BiConsumer<Object,Long> consumer)

Description copied from interface: Block

consumer visits each of the internal data container and accepts the size for it. This method can be helpful in cases such as memory counting for internal data structure. Also, the method should be non-recursive, only visit the elements at the top level, and specifically should not call retainedBytesForEachPart on nested blocks consumer should be called at least once with the current block and must include the instance size of the current block

getValues

protected Block getValues()

Specified by:

getValues in class AbstractArrayBlock

getOffsets

protected int[] getOffsets()

Specified by:

getOffsets in class AbstractArrayBlock

getOffsetBase

getValueIsNull

protected boolean[] getValueIsNull()

Specified by:
