Method Details

launch

public boolean launch(Node node, Heap heap) throws PipelineRunException

Actually executes the Node passed as parameter. The method is responsible for : - extracting the node's input parameters from the Heap - identifying the node's method signature - upon success: push the return values to the Heap - upon failure: either abort the Node, stop or abort the Runtime Note that in the current implementation, only "blocking" errors are handled, resulting in a complete exit from the pipe. Returning false was designed as a mean for a "soft exit" which results in blocking downstream paths while continuing on running paths that are still valid.

Parameters:

node - Target node

heap - Heap object used for retrieving module parameters

Returns:

true upon a successful execution, false otherwise

Throws:

PipelineRunException
