Constructor Details

DoubleArrowBufBlock

public DoubleArrowBufBlock(org.apache.arrow.memory.ArrowBuf valueBuffer,
 @Nullable
 org.apache.arrow.memory.ArrowBuf validityBuffer,
 @Nullable
 org.apache.arrow.memory.ArrowBuf offsetBuffer,
 int valueCount,
 int offsetCount,
 BlockFactory blockFactory)

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