public class Mathrel

extends AbstractMathCode

This class provides an implementation for the primitive \mathrel.

The Math Primitive \mathrel

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

Syntax

    ⟨mathrel⟩
       → \mathrel ⟨formula⟩

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

Examples

    \mathrel x 

    \mathrel\mathchar"1234  

    \mathrel {abc}

             throws InterpreterException

Description copied from interface: Code

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

Throws:

InterpreterException
