Control sequence definitions.
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.
Returns the (main) token that is bound to this definition.
Returns the string form of the token bound to this definition, taking into account any alias for this definition.
Reads the arguments for this $defn from the $gullet, returning a list of LaTeXML::Core::Tokens.
Return the LaTeXML::Core::Parameters object representing the formal parameters of the definition.
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).
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.
