Noalign

public Noalign(CodeToken token)

Creates a new object.

Parameters:

token - the initial token for the primitive

Method Detail

execute

public 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.

Specified by:

execute in interface Code

Overrides:

execute in class AbstractCode

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

exec

public NodeList exec(Context context,
                     TokenSource source,
                     Typesetter typesetter,
                     Token start)
              throws HelpingException,
                     TypesetterException

Acquire the vbox to be inserted as alignment.

Parameters:

context - the interpreter context

source - the token source

typesetter - the typesetter

start - the start token

Returns:

the vbox acquired

Throws:

HelpingException - in case of an error

TypesetterException - in case of an error in the typesetter
