RowReferencePageManager.LoadCursor (presto-main 350 API)

java.lang.Object
- io.prestosql.operator.RowReferencePageManager.LoadCursor

All Implemented Interfaces:

AutoCloseable

Enclosing class:

RowReferencePageManager
```
public static class RowReferencePageManager.LoadCursor
extends Object
implements AutoCloseable
```
Cursor that allows callers to advance through the registered page and dictate whether a specific position should be preserved with a stable row ID. Row ID generation can be expensive in tight loops, so this allows callers to quickly skip positions that won't be needed.
