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
...
}

..like this, for instance, a SpotLight node from a scene graph which will be default off when read back from file:

SpotLight {
on FALSE
}

Constructor & Destructor Documentation

◆ ~SoSField()

SoSField::~SoSField ( )
virtual

The SoSField destructor is empty, and is only defined so we could make it virtual.

◆ SoSField()

SoSField::SoSField ( void  )
protected

The SoSField constructor is protected, as this is an abstract class.


The documentation for this class was generated from the following files:
