Class GenericResponse

    java.lang.Object
      org.apache.cayenne.util.GenericResponse

All Implemented Interfaces:
  Serializable, QueryResponse

    public class GenericResponse

extends Object
implements QueryResponse, Serializable

A simple serializable implementation of QueryResponse.

Field Summary
`protected int` | `currentIndex`
`protected List` | `results`

Constructor Summary
`GenericResponse()` Creates an empty BaseResponse.
`GenericResponse(List list)` Creates a BaseResponse with a single result list.
`GenericResponse(QueryResponse response)` Creates a response that it a shallow copy of another response.

Method Summary
`void` | `addBatchUpdateCount(int[] resultCount)`
`void` | `addResultList(List list)`
`void` | `addUpdateCount(int resultCount)`
`void` | `clear()` Clears any previously collected information.
`List` | `currentList()` Returns a List under the current iterator position.
`int[]` | `currentUpdateCount()` Returns an update count under the current iterator position.
`List` | `firstList()` A utility method for quickly retrieving the first list in the response.
`int[]` | `firstUpdateCount()` A utility method for quickly retrieving the first update count from the response.
`boolean` | `isList()` Returns whether current iteration result is a list or an update count.
`boolean` | `next()` Rewinds response iterator to the next result, returning true if it is available.
`void` | `replaceResult(Object oldResult, Object newResult)` Replaces previously stored result with a new result.
`void` | `reset()` Restarts response iterator.
`int` | `size()` Returns a number of results in the response.

Field Detail

### results

    protected List results

### currentIndex

    protected transient int currentIndex

Constructor Detail

### GenericResponse

    public GenericResponse()

  Creates an empty BaseResponse.

### GenericResponse

    public GenericResponse(List list)

  Creates a BaseResponse with a single result list.

### GenericResponse

    public GenericResponse(QueryResponse response)

  Creates a response that it a shallow copy of another response.

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 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`

### currentList

    public 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 accommodate 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`

### 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`

### 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`

### size

    public int size()

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

  Specified by:
    `size` in interface `QueryResponse`

### clear

    public void clear()

  Clears any previously collected information.

### addBatchUpdateCount

    public void addBatchUpdateCount(int[] resultCount)

### addUpdateCount

    public void addUpdateCount(int resultCount)

### addResultList

    public void addResultList(List list)

### replaceResult

    public void replaceResult(Object oldResult,
                              Object newResult)

  Replaces previously stored result with a new result.
