Method Detail

### size

    public int size()

  Description copied from interface: `QueryResponse`
  Returns a number of results in the response.

  Specified by:
    `size` in interface `QueryResponse`

### 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 interface `QueryResponse`

### currentList

    public java.util.List currentList()

  Description copied from interface: `QueryResponse`
  Returns a List under the current iterator position. Use `QueryResponse.isList()` to check the result type before calling this method.

  Specified by:
    `currentList` in interface `QueryResponse`

### currentUpdateCount

    public int[] currentUpdateCount()

  Description copied from interface: `QueryResponse`
  Returns an update count under the current iterator position. Returned value is an int[] to accomodate batch queries. For a regular update result, the value will be an int[1]. Use `QueryResponse.isList()` to check the result type before calling this method.

  Specified by:
    `currentUpdateCount` in interface `QueryResponse`

### 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 interface `QueryResponse`

### reset

    public void reset()

  Description copied from interface: `QueryResponse`
  Restarts response iterator.

  Specified by:
    `reset` in interface `QueryResponse`

### firstList

    public java.util.List firstList()

  Description copied from interface: `QueryResponse`
  A utility method for quickly retrieving the first list in the response. Note that this method resets current iterator to an undefined state.

  Specified by:
    `firstList` in interface `QueryResponse`

### 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 interface `QueryResponse`
