SoSField — 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.

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.
