All Implemented Interfaces:, GlueConvertible, Code

public class Mutoglue
extends AbstractCode
implements GlueConvertible

This class provides an implementation for the primitive \mutoglue.

The Primitive \mutoglue

The primitive \mutoglue converts a muglue specification to a glue specification. For this conversion 1mu=1pt is assumed. This primitive can be used wherever a glue is expected.


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

                 throws HelpingException,
This method converts a register into a glue value. It might be necessary to read further tokens to determine which value to use. For instance an additional register number might be required. In this case the additional arguments Context and TokenSource can be used.

Specified by:
convertGlue in interface GlueConvertible
context - the interpreter context
source - the source for new tokens
typesetter - the typesetter to use for conversion
the converted value
HelpingException - in case of an error
TypesetterException - in case of an error in the typesetter
