Method Detail

destroy

public void destroy()

Description copied from interface: Processlet

Called by the WPService 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.

Specified by:

destroy in interface Processlet

init

public void init()

Description copied from interface: Processlet

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

Specified by:

init in interface Processlet

process

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

Description copied from interface: Processlet

Called by the WPService 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 ParameterDemoProcesslet as best practice.

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

getExceptionCustomizer

public ExceptionCustomizer getExceptionCustomizer()

Description copied from interface: ExceptionAwareProcesslet

Called by the WPService if an exception occurred while parsing and/or validating an incoming request.

Implementations may supply an ExceptionCustomizer which will create an OWSException appropriate for a number of exceptional events. If an implementations wants the WPService to generate a 'standard' exception null should be returned.

Specified by:

getExceptionCustomizer in interface ExceptionAwareProcesslet

Returns:

an ExceptionCustomizer or null if the Processlet prefers standard exception handling.
