de.dante.extex.interpreter.primitives.register.box.Copy
- All Implemented Interfaces:
- Boxable, BoxOrRule, Code, Localizable, java.io.Serializable
- public class Copy
- extends BoxPrimitive
- implements Boxable, java.io.Serializable
This class provides an implementation for the primitive \copy
.
The Primitive \copy
The primitive \copy inserts the contents of the named box register
at the current position. In contrast to the
\box
primitive the box register is not cleared.
If the primitive is used on the right hand side of a box assignment then
the box contents is used for the assignment.
Syntax
The formal description of this primitive is the following:
〈copy〉
→ \copy 〈box register name〉

- 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:
