Detailed Description

This class is used by the SoDB reading routines when reading Inventor data files. It supports both ASCII (default) and binary Inventor formats. Users can also register additional valid file headers. When reading, SoInput skips over Inventor comments (from '#' to end of line) and can stack input files. When EOF is reached, the stack is popped. This class can also be used to read from a buffer in memory.

Constructor & Destructor Documentation

◆ SoInput() [1/2]

SoInput::SoInput ( )

The default SoInput reads from stdin. The destructor closes any files opened by the SoInput.

◆ ~SoInput()

SoInput::~SoInput ( )

The default SoInput reads from stdin. The destructor closes any files opened by the SoInput.

◆ SoInput() [2/2]

SoInput::SoInput ( SoInput * dictIn )

The default SoInput reads from stdin. The destructor closes any files opened by the SoInput.
