Method Detail
-
firstList
public List firstList()
Description copied from interface:QueryResponse
A utility method for quickly retrieving the first list in the response. Returns null if the query has no lists. Note that this method resets current iterator to an undefined state.- Specified by:
firstList
in interfaceQueryResponse
-
firstUpdateCount
public int[] firstUpdateCount()
Description copied from interface:QueryResponse
A utility method for quickly retrieving the first update count from the response. Note that this method resets current iterator to an undefined state.- Specified by:
firstUpdateCount
in interfaceQueryResponse
-
currentList
public List currentList()
Description copied from interface:QueryResponse
Returns a List under the current iterator position. UseQueryResponse.isList()
to check the result type before calling this method.- Specified by:
currentList
in interfaceQueryResponse
-
currentUpdateCount
public int[] currentUpdateCount()
Description copied from interface:QueryResponse
Returns an update count under the current iterator position. Returned value is an int[] to accommodate batch queries. For a regular update result, the value will be an int[1]. UseQueryResponse.isList()
to check the result type before calling this method.- Specified by:
currentUpdateCount
in interfaceQueryResponse
-
isList
public boolean isList()
Description copied from interface:QueryResponse
Returns whether current iteration result is a list or an update count.- Specified by:
isList
in interfaceQueryResponse
-
next
public boolean next()
Description copied from interface:QueryResponse
Rewinds response iterator to the next result, returning true if it is available.- Specified by:
next
in interfaceQueryResponse
-
reset
public void reset()
Description copied from interface:QueryResponse
Restarts response iterator.- Specified by:
reset
in interfaceQueryResponse
-
size
public int size()
Description copied from interface:QueryResponse
Returns a number of results in the response.- Specified by:
size
in interfaceQueryResponse
