- All Implemented Interfaces:
- java.io.Serializable, Code
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
The formal description of this primitive is the following:
〈mathop〉
→ \mathop 〈formula〉
〈formula〉
→ 〈letter〉
| { 〈math material〉 }
Examples
\mathop x
\mathop\mathchar"1234
\mathop {abc}

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. |
