public class Mathop
extends AbstractMathCode

This class provides an implementation for the primitive \mathop.

The Math Primitive \mathop

The primitive \mathop takes an argument and treats it as an operator symbol. It works in math mode only. The argument can either be a single letter of a math expression enclosed in braces.

Syntax

    ⟨mathop⟩
       → \mathop ⟨formula⟩

    ⟨formula⟩
       →  ⟨letter⟩
         |  { ⟨math material⟩ }  

Examples

    \mathop x 

    \mathop\mathchar"1234  

    \mathop {abc}

Mathop

public Mathop(CodeToken token)

Creates a new object.

Parameters:

token - the initial token for the primitive

execute

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

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:

TypesetterException - in case of an error in the typesetter

HelpingException - in case of an error
