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.
