Interface Divideable

All Known Implementing Classes:

public interface Divideable

This is a interface to mark those classes which are able to divide something.

Extending \divide

The primitive \divide is designed to be expanded. It is fairly simple to write a dividable primitive. The associated code simply has to implement the interface Divideable. Whenever \divide is encountered immediately followed by a token which has the proper code associated, the method divide is invoked. It is up to this method to gather further arguments and perform the division.

With this interface the division is in fact tied to the implementing code and not to the primitive \divide. Each primitive can be made aware for division without touching the code for \divide.

Method Summary

void	divide(Flags prefix, Context context, TokenSource source, Typesetter typesetter) This method is called when the macro \divide has been seen.

Method Detail

divide

void divide(Flags prefix,
            Context context,
            TokenSource source,
            Typesetter typesetter)
            throws HelpingException,
                   TypesetterException

This method is called when the macro \divide has been seen. It performs the remaining tasks for the expansion.

Parameters:

prefix - the prefix for the command

context - the processor context

source - the token source to parse

typesetter - the typesetter

Throws:

HelpingException - in case of an error

TypesetterException - in case of an error in the typesetter

ConfigurationException - in case of an configuration error
