org.gridgain.grid.gridify
Class GridifyJobAdapter

java.lang.Object
  org.gridgain.grid.GridJobAdapter<GridifyArgument>
      org.gridgain.grid.gridify.GridifyJobAdapter

All Implemented Interfaces:

Serializable, GridJob

public class GridifyJobAdapter
extends GridJobAdapter<GridifyArgument>

Convenience adapter for custom gridify jobs. In addition to functionality provided in GridJobAdapter adapter, this adapter provides default implementation of GridifyJobAdapter.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 GridJobAdapter should be used.

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

Method Detail

execute

public Serializable 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.

Throws:

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

Returns:

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