BlockApiHandle (Apache Giraph Parent 1.4.0-SNAPSHOT API)

```
public class BlockApiHandle
extends Object
```
Class that contains references to Block Api objects. One general use-case for this is for applications to indirectly get a handle on the Block Api objects and implement operations that (i) depend on the Block Api interfaces, (ii) are not in the context of a Piece when defined, and (iii) are in the context of a Piece when executed. To do this, as opposed to defining an application as a Block, define your application as a BlockWithApiHandle. NOTE: Depending on the context in which this class is used, some of the handles may not be set. For instance, the masterApi is not set when this is in the context of a worker. Trying to get access to a handle when it is not set will result in a runtime exception. Instead, you should first use methods like the isMasterApiSet() to check. The *Api fields are transient as we do not need/want to serialize them. They will be set at the appropriate time by the framework.
