public interface VectorSizeInspector

Common interface for vectorized column selectors, matchers, etc, where callers are given the ability to inspect current and maximum vector sizes.

Method Summary

Modifier and Type	Method and Description
int	getCurrentVectorSize() Returns the current vector size for this cursor.
int	getMaxVectorSize() Returns the maximum vector size for this cursor.

Method Detail

getMaxVectorSize

int getMaxVectorSize()

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.

getCurrentVectorSize

int getCurrentVectorSize()

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