Method Detail

process

public void process(ProcessletInputs in,
                    ProcessletOutputs out,
                    ProcessletExecutionInfo info)
             throws ProcessletException

Description copied from interface: Processlet

Called by the ProcessManager to perform the execution of this Processlet.

The typical workflow is:

1. Get inputs from in parameter
2. Parse inputs into the required format (e.g. GML)
3. Do computation.
4. Transform computational results into required format (e.g. GML)
5. Write results to out parameter

Please consider the corresponding wiki howto.

Specified by:

process in interface Processlet

Parameters:

in - input arguments to be processed, never null

out - used to store the process outputs, never null

info - can be used to provide execution information, i.e. percentage completed and start/success messages that it wants to make known to clients, never null

Throws:

ProcessletException - may be thrown by the processlet to indicate a processing exception

init

public void init()

Description copied from interface: Processlet

Called by the ProcessManager to indicate to a Processlet that it is being placed into service.

Specified by:

destroy

public void destroy()

Description copied from interface: Processlet

Called by the ProcessManager to indicate to a Processlet that it is being taken out of service.

This method gives the Processlet an opportunity to clean up any resources that are being held (for example, memory, file handles, threads) and make sure that any persistent state is synchronized with the Processlet's current state in memory.
