-- Verbatim class
-- Represents a line translated directed to the binding file.
-- The following filds are stored:
-- line = line text
classVerbatim = {
line = '',
cond = nil, -- condition: where to generate the code (s=suport, r=register)
}
classVerbatim.__index = classVerbatim
setmetatable(classVerbatim,classFeature)
-- preamble verbatim
function classVerbatim:preamble ()
if self.cond == '' then
write(self.line)
end
end
-- support code
function classVerbatim:supcode ()
if strfind(self.cond,'s') then
write(self.line)
write('\n')
end
end
-- register code
function classVerbatim:register (pre)
if strfind(self.cond,'r') then
write(self.line)
end
end
-- Print method
function classVerbatim:print (ident,close)

-- Internal constructor
function _Verbatim (t)

-- Constructor
-- Expects a string representing the text line
function Verbatim (l,cond)
