Detailed Description
A field converter engine is used to convert the value of a field of one type to another. These engines are registered with the global database so connections between fields of different types can be made by automatically inserting a converter instance. A single class of converter engine may be registered for several different conversions. Field converters are never written to file (SoField::writeConnection takes care of that).

Member Function Documentation
| virtual SoField* SoFieldConverter::getConnectedInput | ( | ) | [virtual] |
By default, this searches through the field data for the field that is connected; you can redefine to make more efficient.
| int SoFieldConverter::getForwardConnections | ( | SoFieldList & | list | ) | const |
They return the input and output connections of the given types.
| virtual SoEngineOutput* SoFieldConverter::getOutput | ( | SoType | type | ) | [pure virtual] |
| static void SoFieldConverter::initClass | ( | ) | [static] |
Reimplemented from SoEngine.
| static void SoFieldConverter::initClasses | ( | ) | [static] |
Reimplemented from SoEngine.
