Constructor Details

LongMul1kArrowBufVector

public LongMul1kArrowBufVector(org.apache.arrow.memory.ArrowBuf valueBuffer,
 int positionCount,
 BlockFactory blockFactory)

Create an ArrowBuf vector based on the constituents of an Arrow ValueVector. The caller must retain the buffers if they are shared with other blocks or Arrow vectors.

elementType

public ElementType elementType()

Description copied from interface: Vector

Returns the element type of this vector.

Specified by:

elementType in interface Vector

Returns:

the element type of this vector

lookup

public org.elasticsearch.core.ReleasableIterator<LongBlock> lookup(IntBlock positions,
 ByteSizeValue targetBlockSize)

Description copied from interface: Vector

Builds an Iterator of new Blocks with the same Vector.elementType() as this Vector whose values are copied from positions in this Vector. It has the same number of positions as the positions parameter.

For example, if this vector contained [a, b, c] and were called with the block [0, 1, 1, [1, 2]] then the result would be [a, b, b, [b, c]].

This process produces count(positions) values per positions which could be quite large. Instead of returning a single Block, this returns an Iterator of Blocks containing all of the promised values.

The returned ReleasableIterator may retain a reference to the positions parameter. Close it to release those references.

This block is built using the same BlockFactory as was used to build the positions parameter.

slice

public LongVector slice(int beginInclusive,
 int endExclusive)

Description copied from interface: LongVector

Return a subset of this vector from beginInclusive to endExclusive. This may return the same instance if the range covers all positions, but if it does it will RefCounted.incRef() it.
