Control sequence definitions.
This class represents control sequences that contribute arbitrary XML fragments to the document tree. During digestion, a LaTeXML::Core::Definition::Constuctor records the arguments used in the invocation to produce a LaTeXML::Core::Whatsit. The resulting LaTeXML::Core::Whatsit (usually) generates an XML document fragment when absorbed by an instance of LaTeXML::Core::Document. Additionally, a LaTeXML::Core::Definition::Constructor may have beforeDigest and afterDigest daemons defined which are executed for side effect, or for adding additional boxes to the output.
It extends LaTeXML::Core::Definition.
More documentation needed, but see LaTeXML::Package for the main user access to these.
A constructor has as it’s replacement a subroutine or a string pattern representing the XML fragment it should generate. In the case of a string pattern, the pattern is compiled into a subroutine on first usage by the internal class LaTeXML::Core::Definition::ConstructorCompiler. Like primitives, constructors may have beforeDigest and afterDigest.
