Method Details

writeLong

public BlockBuilder writeLong(long value)

append

public void append(ValueBlock block,
 int position)

Description copied from interface: BlockBuilder

Append the specified value.

Specified by:

append in interface BlockBuilder

appendRepeated

public void appendRepeated(ValueBlock block,
 int position,
 int count)

Description copied from interface: BlockBuilder

Append the specified value multiple times.

Specified by:

appendRepeated in interface BlockBuilder

appendRange

public void appendRange(ValueBlock block,
 int offset,
 int length)

Description copied from interface: BlockBuilder

Append the values in the specified range.

Specified by:

appendRange in interface BlockBuilder

appendPositions

public void appendPositions(ValueBlock block,
 int[] positions,
 int offset,
 int length)

Description copied from interface: BlockBuilder

Append the values at the specified positions.

Specified by:

appendPositions in interface BlockBuilder

appendNull

public BlockBuilder appendNull()

Description copied from interface: BlockBuilder

Appends a null value to the block.

Specified by:

appendNull in interface BlockBuilder

resetTo

public void resetTo(int position)

Description copied from interface: BlockBuilder

Rolls back added data to the specified position. Resetting may result in a block without nulls with the may-have-nulls flag set. The PageBuilder status will not be updated to reflect the removed data size.

Specified by:

resetTo in interface BlockBuilder

build

public Block build()

Description copied from interface: BlockBuilder

Builds the block. This method can be called multiple times. The return value may be a block such as RLE to allow for optimizations when all block values are the same.

Specified by:

build in interface BlockBuilder

buildValueBlock

public LongArrayBlock buildValueBlock()

Description copied from interface: BlockBuilder

Builds a ValueBlock. This method can be called multiple times.

Specified by:

buildValueBlock in interface BlockBuilder

newBlockBuilderLike

public BlockBuilder newBlockBuilderLike(int expectedEntries,
 BlockBuilderStatus blockBuilderStatus)

Description copied from interface: BlockBuilder

Creates a new block builder of the same type based on the current usage statistics of this block builder.

Specified by:

newBlockBuilderLike in interface BlockBuilder

getSizeInBytes

public long getSizeInBytes()

Description copied from interface: BlockBuilder

Returns the size of this block as if it was compacted, ignoring any over-allocations and any unloaded nested blocks. For example, in dictionary blocks, this only counts each dictionary entry once, rather than each time a value is referenced.

Specified by:

getSizeInBytes in interface BlockBuilder

getRetainedSizeInBytes

public long getRetainedSizeInBytes()

Description copied from interface: BlockBuilder

Returns the retained size of this block in memory, including over-allocations. This method is called from the innermost execution loop and must be fast.

Specified by:

getRetainedSizeInBytes in interface BlockBuilder

getPositionCount

public int getPositionCount()

Description copied from interface: BlockBuilder

Returns the number of positions in this block builder.

Specified by:

getPositionCount in interface BlockBuilder

toString

public String toString()

Overrides:

toString in class Object
