Method Summary

void	cr(Context context, TokenSource source, NodeList noalign) This method is invoked when a row in the alignment is complete and the cells can be integrated.
void	crcr(Context context, TokenSource source, Typesetter typesetter) This method is invoked when a row in the alignment is complete and the cells can be integrated.
void	omit() The invocation of this method indicates that the pattern for the current cell should not be taken from the preamble but the default should be used instead.
void	span(Context context, TokenSource source) This method is invoked when a cell is complete which should be continued in the next cell.

Method Detail

cr

void cr(Context context,
        TokenSource source,
        NodeList noalign)
        throws TypesetterException

This method is invoked when a row in the alignment is complete and the cells can be integrated. If some cells are not filled jet then they are treated as empty.

Parameters:

context - the interpreter context

source - the token source

noalign - the tokens to be inserted or null

Throws:

TypesetterException - in case of an error

crcr

void crcr(Context context,
          TokenSource source,
          Typesetter typesetter)
          throws TypesetterException

This method is invoked when a row in the alignment is complete and the cells can be integrated. If some cells are not filled jet then they are treated as empty. In contrast to the method cr() this method is a noop when the alignment is at the beginning of a row.

Parameters:

context - the interpreter context

source - the token source

typesetter - the typesetter

Throws:

TypesetterException - in case of an error

omit

void omit()
          throws TypesetterException

The invocation of this method indicates that the pattern for the current cell should not be taken from the preamble but the default should be used instead.

Throws:

TypesetterException - in case of an error

span

void span(Context context,
          TokenSource source)
          throws TypesetterException

This method is invoked when a cell is complete which should be continued in the next cell.

Parameters:

context - the interpreter context

source - the token source

Throws:

TypesetterException - in case of an error
