NAME

       "LaTeXML::Core::Definition"  - Control sequence definitions.

DESCRIPTION

       This abstract class represents the various executables corresponding to control sequences.
       See LaTeXML::Package for the most convenient means to create them.

       It extends LaTeXML::Common::Object.

   Methods
       "$token = $defn->getCS;"
           Returns the (main) token that is bound to this definition.

       "$string = $defn->getCSName;"
           Returns the string form of the token bound to this definition, taking into account any
           alias for this definition.

       "$defn->readArguments($gullet);"
           Reads the arguments for this $defn from the $gullet, returning a list of
           LaTeXML::Core::Tokens.

       "$parameters = $defn->getParameters;"
           Return the "LaTeXML::Core::Parameters" object representing the formal parameters of
           the definition.

       "@tokens = $defn->invocation(@args);"
           Return the tokens that would invoke the given definition with the provided arguments.
           This is used to recreate the TeX code (or it's equivalent).

       "$defn->invoke;"
           Invoke the action of the $defn.  For expandable definitions, this is done in the
           Gullet, and returns a list of LaTeXML::Core::Tokens.  For primitives, it is carried
           out in the Stomach, and returns a list of LaTeXML::Core::Boxes.  For a constructor, it
           is also carried out by the Stomach, and returns a LaTeXML::Core::Whatsit.  That
           whatsit will be responsible for constructing the XML document fragment, when the
           LaTeXML::Core::Document invokes "$whatsit-"beAbsorbed($document);>.

           Primitives and Constructors also support before and after daemons, lists of
           subroutines that are executed before and after digestion.  These can be useful for
           changing modes, etc.
