public interface Code

This is the interface for all expandable or executable classes.

Each primitive has a name which is used for debugging purposes. Since an arbitrary sequence of \let and \def operations might have taken place it is in general not possible to determine the current name under which the primitive has been called. Thus an initial value is stored in it for this purpose.

isIf

boolean isIf()

This simple little method distinguishes the conditionals from the other primitives. This is necessary for the processing of all \if* primitives.

Returns:

true iff this is some sort if \if.

isOuter

boolean isOuter()

Getter for the outer flag.

Returns:

true iff the code is defined outer.

getName

java.lang.String getName()

Deprecated. access the token instead

Getter for the name.

Returns:

the name

getToken

CodeToken getToken()

Getter for the token.

Returns:

the token

execute

void execute(Flags prefix,
             Context context,
             TokenSource source,
             Typesetter typesetter)
             throws HelpingException,
                    TypesetterException

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.

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

ConfigurationException - in case of an configuration error
