org.extex.unit.tex.font.Skewchar
public class Skewchar
This class provides an implementation for the primitive
TODO missing documentation
The TeXbook gives no indication ow the primitive should react for negative
values – except -1. The implementation of \skewchar
.
The Primitive \skewchar
Syntax
The formal description of this primitive is the following:
〈skewchar〉
→ \skewchar 〈font〉 〈equals〉 〈8-bit number〉
Examples
\skewchar\font=123
Incompatibility

convertCount(Context context,
TokenSource source,
Typesetter typesetter)
This method converts a register into a count. |
void |
expand(Flags prefix,
Context context,
TokenSource source,
Typesetter typesetter)
This method takes the first token and expands it. |

execute()
.
This method is preferable to execute() since the
execute() method provided in this class takes care of
\afterassignment and \globaldefs as well.
