Details

The base class for commands. A command is the root of the grammar match tree for a single action. A command line can consist of a number of commands joined with command separators; in English, command separators are things like periods, semicolons, commas, and the words "and" and "then".

Properties

getActorPhrase parser.t[674]

Get the match tree for the target actor phrase, if any. By default, we have no target actor phrase, so just return nil.

Methods

execActorPhrase (issuingActor) parser.t[683]

"Execute" the actor phrase. This lets us know that the parser has decided to use our phrasing to specify the target actor. We're not required to do anything here; it's just a notification for subclass use. Since we don't have a target actor phrase at all, we obviously don't need to do anything here.
