public interface ElementAddressableVector
extends ValueVector

Vector for which each data element resides in a continuous memory region, so it can be pointed to by an ArrowBufPointer.

Method Details

getDataPointer

ArrowBufPointer getDataPointer(int index)

Gets the pointer for the data at the given index.

Parameters:

index - the index for the data.

Returns:

the pointer to the data.

getDataPointer

ArrowBufPointer getDataPointer(int index,
 ArrowBufPointer reuse)

Gets the pointer for the data at the given index.

Parameters:

index - the index for the data.

reuse - the data pointer to fill, this avoids creating a new pointer object.

Returns:

the pointer to the data, it should be the same one as the input parameter
