An iterable query result based on a cursor.
The close()
method 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.

Method Summary

close()
Closes the query result and releases the underlying resources held by the cursor.boolean
Indicates if the query result must be closed (because it holds resources).long
pos()
Gets the current position in the iterator.long
size()
Gets the total size of the query result.void
skipTo
(long pos) Skips to a given position in the iterator.Methods inherited from interface java.lang.Iterable

mustBeClosed
boolean mustBeClosed()Indicates if the query result must be closed (because it holds resources).- Returns:
true
if the query result must be closed,false
otherwise- Since:
- 8.1
-
size
long size()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
-1
will be returned.- Returns:
- the size, or
-1
for an unknown size
-
pos
long pos()Gets the current position in the iterator.Positions start at
0
.- Returns:
- the position
-
skipTo
void skipTo(long pos) Skips to a given position in the iterator.Positions start at
0
