Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`begin()` Starts an asynchronous load.
`boolean`	`canNotifyCleared(Request request)` Returns `true` if the `Request` can clear the `Target`.
`boolean`	`canNotifyStatusChanged(Request request)` Returns true if the `Request` can display a placeholder.
`boolean`	`canSetImage(Request request)` Returns true if the `Request` can display a loaded bitmap.
`void`	`clear()` Prevents any bitmaps being loaded from previous requests, releases any resources held by this request, displays the current placeholder if one was provided, and marks the request as having been cancelled.
`RequestCoordinator`	`getRoot()` Returns the top most parent `RequestCoordinator`.
`boolean`	`isAnyResourceSet()` Returns true if any coordinated `Request` has successfully completed.
`boolean`	`isCleared()` Returns true if the request has been cleared.
`boolean`	`isComplete()` Returns true if the request has completed successfully.
`boolean`	`isEquivalentTo(Request o)` Returns `true` if this `Request` is equivalent to the given `Request` (has all of the same options and sizes).
`boolean`	`isRunning()` Returns true if this request is running and has not completed or failed.
`void`	`onRequestFailed(Request request)` Must be called when a `Request` coordinated by this object fails.
`void`	`onRequestSuccess(Request request)` Must be called when a `Request` coordinated by this object completes successfully.
`void`	`pause()` Similar to `Request.clear()` for in progress requests (or portions of a request), but does nothing if the request is already complete.
`void`	`setRequests(Request primary, Request error)`

  - clear
```
public void clear()
```
    Description copied from interface: Request
    
    Prevents any bitmaps being loaded from previous requests, releases any resources held by this request, displays the current placeholder if one was provided, and marks the request as having been cancelled.
    
    Specified by:
    
    clear in interface Request
  - pause
```
public void pause()
```
    Description copied from interface: Request
    
    Similar to Request.clear() for in progress requests (or portions of a request), but does nothing if the request is already complete.
    Unlike Request.clear(), this method allows implementations to act differently on subparts of a request. For example if a Request has both a thumbnail and a primary request and the thumbnail portion of the request is complete, this method allows only the primary portion of the request to be paused without clearing the previously completed thumbnail portion.
    
    Specified by:
    
    pause in interface Request
  - isRunning
```
public boolean isRunning()
```
    Description copied from interface: Request
    
    Returns true if this request is running and has not completed or failed.
    
    Specified by:
    
    isRunning in interface Request
  - isComplete
```
public boolean isComplete()
```
    Description copied from interface: Request
    
    Returns true if the request has completed successfully.
    
    Specified by:
    
    isComplete in interface Request
  - isCleared
```
public boolean isCleared()
```
    Description copied from interface: Request
    
    Returns true if the request has been cleared.

    isCleared in interface Request
  - isEquivalentTo
```
public boolean isEquivalentTo(Request o)
```
    Description copied from interface: Request
    
    Returns true if this Request is equivalent to the given Request (has all of the same options and sizes).
    This method is identical to Object.equals(Object) except that it's specific to Request subclasses. We do not use Object.equals(Object) directly because we track Requests in collections like Set and it's perfectly legitimate to have two different Request objects for two different Targets (for example). Using a similar but different method let's us selectively compare Request objects to each other when it's useful in specific scenarios.

    Description copied from interface: RequestCoordinator
