54 SoEngine is the abstract base class for all engines. Engines are
55 objects used for animation and behavior. They are lightweight objects
56 that are connected between nodes, the clock, and other engines to form
57 interesting behaviorial objects (e.g., a spinning windmill).
58 Engines are used to animate parts of a scene and/or to constrain one
60 part of a scene in relation to some other part of the scene. An engine
61 receives a number of input values, performs some operation on them, and
62 then copies the results into one or more output fields. Both the inputs
63 and the outputs can be connected to other fields or engines in the
64 scene graph. When an engine's output values change, those new values
65 are sent to any fields or engines connected to them.
66
68 static SoType getClassTypeId()
69 Returns the type identifier for the SoEngine class.
70 virtual int getOutputs(SoEngineOutputList &list) const
72 Returns a list of outputs in this engine. Use getOutputName to get
73 the names of the outputs, and use SoEngineOutput::getConnectionType
74 to determine their types.
75 SoEngineOutput * getOutput(const SbName &outputName) const
77 Returns a pointer to the engine output with the given name. If no
78 such output exists, NULL is returned.
79 SbBool getOutputName(const SoEngineOutput *output, SbName
81 &outputName) const
82 Returns (in outputName) the name of the engine output (output).
83 Returns FALSE if the engine output is not contained within the
84 engine instance.
85 SoEngine * copy() const
87 Creates and returns an exact copy of the engine. All connections to
88 inputs are copied as is (without copying what's at the other end).
89 static SoEngine * getByName(const SbName &name)
91 static int getByName(const SbName &name, SoEngineList &list)
92 Look up engine(s) by name.

96 This is an abstract class. See the reference page of a derived class
97 for the format and default values.
