Reimplemented from DtRailSegment.

virtual void DtRwRailSegment::putSelf ( FILE *  fp, int  indentLevel = 0, bool  writeUnspecified = false, const DtFilename &  path = DtFilename::nullFilename()  )

virtual

Top level call to write itself to file.

If write unspecified is true, will write entries that are unspecified, in the format (name <use-default>). Path is passed down to all DtReaderWriter members in its DtReaderWriterRegistry (collection of child DtReaderWriter nodes). If a given member in the registry is of type DtReaderWriterFile, and the path is specified with a non-NULL string, then the path prepended to the filename before writing the entry to file.

Reimplemented from DtReaderWriter.

virtual const char* DtRwRailSegment::readerWriterType ( ) const

virtual

Used to supply a string type that this reader writer type is.

This can be used in place of dynamic-casting. Also used by the opd editor to determine which type of control to create
