QueryRange

To support paging of query results, specifies an offset/start instance and limits the number of instances to be retrieved.

Used by NamedQuery#withRange(QueryRange) and AllInstancesQuery#withRange(QueryRange) .

1	isUnconstrained() Whether this range is unconstrained, meaning that there is #hasOffset() no offset and #hasLimit() no limit has been specified.
2	hasOffset() Whether this range has had a non-zero offset specified using #withStart(long) .
3	hasLimit() Whether this range has a limit to the number of instances to be returned using #withLimit(long) .
4	getStart() The start index into the set table. (non-negative)
5	getLimit() The maximum number of items to return, starting at #getStart() (non-negative).
6	getEnd() The end index into the set table. Overflow is ignored. (non-negative)
7	getStartAsInt() The start index into the set table (as java int primitive)
8	getLimitAsInt() The maximum number of items to return (as java int primitive) if limit overflows an int, Integer#MAX_VALUE is returned.
9	getEndAsInt() The end index into the set table. Overflow is ignored. (as java int primitive) if end overflows an int, Integer#MAX_VALUE is returned.

Members

isUnconstrained()

Whether this range is unconstrained, meaning that there is #hasOffset() no offset and #hasLimit() no limit has been specified.

hasOffset()

Whether this range has had a non-zero offset specified using #withStart(long) .

hasLimit()

Whether this range has a limit to the number of instances to be returned using #withLimit(long) .

getStart()

The start index into the set table. (non-negative)

getLimit()

The maximum number of items to return, starting at #getStart() (non-negative).

getEnd()

The end index into the set table. Overflow is ignored. (non-negative)

getStartAsInt()

The start index into the set table (as java int primitive)

getLimitAsInt()

The maximum number of items to return (as java int primitive) if limit overflows an int, Integer#MAX_VALUE is returned.

getEndAsInt()

The end index into the set table. Overflow is ignored. (as java int primitive) if end overflows an int, Integer#MAX_VALUE is returned.
