public class Errorstopmode
extends AbstractAssignment

This class provides an implementation for the primitive \errorstopmode. It does simply nothing, but as a side effect all prefixes are zeroed and the interaction mode is set to errorstopmode.

The Primitive \errorstopmode

This primitive sets the interaction mode to error stop mode. In error stop mode the processing is interrupted and the error handler is invoked when an error occurs.

The setting of the interaction mode is an assignment. The mode is always processed globally. This means it does not interact with the group concept.

Syntax

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

Examples

    \errorstopmode

Parameters:
token - the initial token for the primitive
Method Detail

assign

public void assign(Flags prefix,
                   Context context,
                   TokenSource source,
                   Typesetter typesetter)
            throws HelpingException,
                   TypesetterException
The method assign is the core of the functionality of execute(). This method is preferable to execute() since the execute() method provided in this class takes care of \afterassignment and \globaldefs as well.

Specified by:
assign in class AbstractAssignment
Parameters:
prefix - the prefix controlling the execution
context - the interpreter context
source - the token source
typesetter - the typesetter
Throws:
HelpingException - in case of an error
TypesetterException - in case of an error in the typesetter
