Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	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().
