Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`begin()` Starts an asynchronous load.
`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.
`boolean`	`isAnyResourceSet()` Returns true if any coordinated `Request` has successfully completed.
`boolean`	`isCancelled()` Returns true if the request has been cancelled.
`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`	`isFailed()` Returns true if the request has failed.
`boolean`	`isPaused()` Returns true if this request is paused and may be restarted.
`boolean`	`isResourceSet()` Returns true if a non-placeholder resource is put.
`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()` Identical to `Request.clear()` except that the request may later be restarted.
`void`	`recycle()` Recycles the request object and releases its resources.
`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.

```
public boolean isPaused()
```
    Description copied from interface: Request
    
    Returns true if this request is paused and may be restarted.
    
    Specified by:
    
    isPaused 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
  - isResourceSet
```
public boolean isResourceSet()
```
    Description copied from interface: Request
    
    Returns true if a non-placeholder resource is put. For Requests that load more than one resource, isResourceSet may return true even if Request.isComplete()} returns false.

  - isCancelled
```
public boolean isCancelled()
```
    Description copied from interface: Request

  - recycle
```
public void recycle()

    Description copied from interface: Request
    
    Recycles the request object and releases its resources.
    
    Specified by:
    
    recycle 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.
    
    Specified by:

  - canSetImage
```
public boolean canSetImage(Request request)
```
    Description copied from interface: RequestCoordinator
    
    Returns true if the Request can display a loaded bitmap.
    
    Specified by:
    
    canSetImage in interface RequestCoordinator
    
    Parameters:

```
public boolean canNotifyStatusChanged(Request request)
```
    Description copied from interface: RequestCoordinator
