Detailed Description

Main class for writing groups to a stream.

Library: ilvproto

Group files should not be created directly by the application. They are generated internally by methods of other prototypes library classes. You will never need to use this class directly, unless you write new IlvGroupNode subclasses.

Member Function Documentation

void IlvGroupOutputFile::addIndent ( int  d)

Adds d to the current indentation level of the output context.

Parameters
dCurrent indent level.
ostream& IlvGroupOutputFile::getStream ( )

Returns the output stream associated with this context.

Returns
The output stream associated with this context.
void IlvGroupOutputFile::writeValue ( const IlSymbol s)

See below.

Parameters
sSymbol to write.
void IlvGroupOutputFile::writeValue ( const char *  string)

Lets you safely write strings that may contain special characters.

These member functions allow you to safely write a character string to an IlvGroupFile. The string is placed between quotation marks if it contains special characters. The accessor parameters should be saved using this method rather than the ostream::operator <<(const char*) operator. This lets you read them back in.

Parameters
stringString to write.
