Detailed Description
The SoSField class is the base class for fields which contains only a single value.
All field types which should always contain only a single member value inherits this class. SoSField is an abstract class.
You use methods setValue() and getValue() to store or fetch the value of single-value fields. Example:
SoSpotLight * lightnode = new SoSpotLight; lightnode->on.setValue(TRUE); // The 'on' field of SoSpotLight is // a single value field of type SoSFBool. ... ... // Change lightswitch. if (lightnode->on.getValue() == FALSE) lightnode->on = TRUE; // We can use operator = instead of setValue(). else lightnode->on = FALSE; ...
When nodes, engines or other types of field containers are written to file, their single-value fields are written to file in this format:
containerclass { fieldname value fieldname value ... }
SpotLight { on FALSE }

Constructor & Destructor Documentation
SoSField::~SoSField () [virtual]
The SoSField destructor is empty, and is only defined so we could make it virtual.
SoSField::SoSField (void) [protected]
The SoSField constructor is protected, as this is an abstract class.
Member Function Documentation
void SoSField::initClass (void) [static]
Internal method called upon initialization of the library (from SoDB::init()) to set up the type system.
