                                                 TaskException

Visits an AST node and creates a component task that models the processing to be done on this node.

Parameters:

path - a list containing all the parent nodes of the visited node stating from the root of the AST.

node - the AST Node to be visited.

context - additional parameters.

Returns:

a task component that models the processing to be done on this node.

Throws:

ADLException - if something wrong is found in the AST.

TaskException - if something wrong happens during the instantiation of the task component.
