Class GridifyJobAdapter

java.lang.Object

org.gridgain.grid.compute.GridComputeJobAdapter

org.gridgain.grid.util.gridify.GridifyJobAdapter

All Implemented Interfaces:

Serializable, Callable<Object>, GridComputeJob

public class GridifyJobAdapter
extends GridComputeJobAdapter

Convenience adapter for custom gridify jobs. In addition to functionality provided in GridComputeJobAdapter adapter, this adapter provides default implementation of execute() method, which reflectively executes grid-enabled method based on information provided in GridifyArgument parameter.

Note this adapter is only useful when passing GridifyArgument to remote jobs. In many cases, remote jobs will not require GridifyArgument as they will execute their code without reflection, hence the regular GridComputeJobAdapter should be used.

See Gridify documentation for more information about execution of gridified methods.

Initializes job with argument.

Parameters:

arg - Job argument.

Method Detail

execute

public Object execute()
               throws GridException

Provides default implementation for execution of grid-enabled methods. This method assumes that argument passed in is of GridifyArgument type. It attempts to reflectively execute a method based on information provided in the argument and returns the return value of the method.

If some exception occurred during execution, then it will be thrown out of this method.

Returns:

Job execution result (possibly null). This result will be returned in GridComputeJobResult.getData() method passed into GridComputeTask.result(GridComputeJobResult, List) task method on caller node.

Throws:

GridException - If job execution caused an exception. This exception will be returned in GridComputeJobResult.getException() method passed into GridComputeTask.result(GridComputeJobResult, List) task method on caller node. If execution produces a RuntimeException or Error, then it will be wrapped into GridException.
