Method Detail

getObjectVector

public Object[] getObjectVector()

Description copied from interface: VectorObjectSelector

Get the current vector. Individual elements of the array may be null.

Specified by:

getObjectVector in interface VectorObjectSelector

getMaxVectorSize

public int getMaxVectorSize()

Description copied from interface: VectorSizeInspector

Returns the maximum vector size for this cursor. It will not change for the lifetime of this cursor, and is generally used to allocate scratch arrays for later processing. Will always be greater than zero.

Specified by:

getMaxVectorSize in interface VectorSizeInspector

getCurrentVectorSize

public int getCurrentVectorSize()

Description copied from interface: VectorSizeInspector

Returns the current vector size for this cursor. Will never be larger than the max size returned by VectorSizeInspector.getMaxVectorSize().

Specified by:

getCurrentVectorSize in interface VectorSizeInspector

lookupName

@Nullable
public abstract String lookupName(int id)
