public class Nonscript
extends AbstractMathCode

This class provides an implementation for the primitive \nonscript.

The Math Primitive \nonscript

The primitive can be used in math modes only. It cancels following glue if the current style is script style or scriptscript style.

Syntax

The formal description of this primitive is the following:
    ⟨nonscript⟩
       → \nonscript  

Examples

    \nonscript

Creates a new object.

Parameters:
token - the initial token for the primitive
Method Detail

execute

public void execute(Flags prefix,
                    Context context,
                    TokenSource source,
                    Typesetter typesetter)
             throws HelpingException,
                    ConfigurationException,
                    TypesetterException
This method takes the first token and executes it. The result is placed on the stack. This operation might have side effects. To execute a token it might be necessary to consume further tokens.

Specified by:
execute in interface Code
Overrides:
execute in class AbstractCode
Parameters:
prefix - the prefix controlling the execution
context - the interpreter context
source - the token source
typesetter - the typesetter
Throws:
HelpingException - in case of an error
ConfigurationException - in case of an configuration error
TypesetterException - in case of an error in the typesetter
