Method Detail

onLoad

void onLoad(LoadSourceSectionEvent event)

Invoked whenever a new source section is loaded. The listener might be notified for one source section multiple times but never with the same instrumented node. The order in which multiple source section event listeners are notified matches the order they are attached. Implementation Note: Source load events are notified when the guest language implementation uses a new source by invoking RootNode.getCallTarget() with a root node that uses a new source in Node.getSourceSection(). It assumes that all nodes of an AST have the same source as their root.

Parameters:

event - an event with context information
