close
public void close()
Description copied from interface:IterableQueryResult
Closes the query result and releases the underlying resources held by the cursor.This MUST be called when the query result is no more needed, otherwise underlying resources will be leaked. There is no auto-closing at the end of the iteration.

isLife
public boolean isLife()
Description copied from interface:IterableQueryResult
Indicates if the query result has not been closed- Specified by:
isLife

-
mustBeClosed
public boolean mustBeClosed()
Description copied from interface:IterableQueryResult
Indicates if the query result must be closed (because it holds resources).- Specified by:
mustBeClosed
in interfaceIterableQueryResult
- Returns:
true
if the query result must be closed,false
otherwise

checkNotClosed
protected void checkNotClosed()
-
size
public long size()
Description copied from interface:IterableQueryResult
Gets the total size of the query result.Note that this may be costly, and that some backends may not be able to do this operation, in which case

will be returned.- Specified by:
size
in interfaceIterableQueryResult
- Returns:
- the size, or
-1
for an unknown size
