The SoFieldConverter class is the abstract base class for field converters.
When fields of different types are attempted connected, the Coin library tries to find a field converter class which can be inserted between them, acting as a filter converting values from the master field to values matching the type of the slave field.
If a value type conversion is possible (like between an SoSFFloat field and an SoSFInt32 field, for instance, where we could do a simple typecast for converting the value of one to the other), an SoFieldConverter derived object is inserted.
This class is the abstract base superclass which all such field converters needs to inherit.
Coin comes with one built-in field converter class which takes care of all possible field-to-field conversions we know about. This means applications programmers should seldom need to care about this class, it will probably only be useful if you expand the Coin library with your own field type classes. (Doing so is considered advanced use of the library.)

Default constructor.

Default destructor.
This static method returns the SoType object associated with objects of this class.
|
staticprotected |
Returns the SoFieldData class which holds information about inputs in this engine.
|
staticprotected |
Returns the SoEngineOutputData class which holds information about the outputs in this engine.
|
virtual |
Returns the SoFieldData class which holds information about inputs in this engine.
Reimplemented from SoFieldContainer.
|
virtual |
Returns the SoEngineOutputData class which holds information about the outputs in this engine.
Implements SoEngine.
Initializes all field conversions. Automatically called from SoFieldConverter::initClass() upon initialization of Coin.
Returns input field for the converter engine. Must be overridden in non-abstract converter engine classes.
|
pure virtual |
Returns output for the converter engine. Must be overridden in non-abstract converter engine classes.
This method is obsoleted in Coin. It should probably have been private in OIV.
int SoFieldConverter::getForwardConnections | ( | SoFieldList & | l | ) | const |
Returns fields which are connected as slaves of the engine output.
