                         throws PrintException

Check tokens to see whether space handling is to be treated as special case or not. This depends on various factors like if the LHS or RHS are token sequences or actual tokens themselves.

Parameters:

previous -

current -

Returns:

Throws:

PrintException

isSpecialTokenCase

protected boolean isSpecialTokenCase(Token previous,
                                     Token current)
                              throws PrintException

Check tokens to see whether space handling is to be treated as a special case or not. It only handles non-token-sequence cases.

Parameters:

previous -

current -

Returns:

Throws:

PrintException - is either previous or current is a token sequence.
