IGraphProcessingEnvironment Events

Fired when execution of a pattern matching construct begins.

Fired when a debug emit is executed.

Fired when a debug entity is entered.

Fired when a debug entity is left.

Fired when a debug halt is executed.

Fired when a debug highlight is executed.

Fired when execution of a pattern matching construct ends.

Fired when a sequence iteration is ended.

Fired when a sequence is entered.

Fired when a sequence is left.

Fired after the rewrite step of a rule/after rule execution has completed. Note, that the given matches object may contain invalid entries, as parts of the match may have been deleted!

Fired after the selected match was rewritten and embedded sequences executed.

Fired when sequences have joined (again) their parent thread.

Fired after all requested matches of a multi rule or rule have been matched (after filtering of matches).

Fired after all requested matches of a multi rule or rule have been matched, before filtering of the matches. Allows a lookahead on the matches, on all found matches, in contrast to OnMatchedAfter that only reports the ones that are applied in the end.

Fired when a match was selected for execution (after filtering/selection of matches).

Fired when graph processing is returning back after a switch. (To the main graph, or a subgraph previously switched to.)

Fired before the selected match is rewritten (comparable to the old OnFinishing and OnRewritingNextMatch, now one event, fired per selected match).

Fired after the selected match was rewritten (but before embedded sequences are executed).

Fired when sequences have been spawned (split off) from their parent thread.

Fired when graph processing (rule and sequence execution) is switched to a (sub)graph. (Not fired when the main graph is replaced by another main graph, or initialized.)
