Public Attributes

Exposed Fields
A field that is capable of receiving events via an eventIn to change its value(s), and generating events via an eventOut when its value(s) change.

Detailed Description

Here is the documentation for this node type, from the ISO standard.

+6.65 Switch

The Switch grouping node traverses zero or one of the nodes specified in the choice field.

4.6.5, Grouping and children nodes, describes details on the types of nodes that are legal values for choice.

The whichChoice field specifies the index of the child to traverse, with the first child having index 0. If whichChoice is less than zero or greater than the number of nodes in the choice field, nothing is chosen.

All nodes under a Switch continue to receive and send events regardless of the value of whichChoice. For example, if an active TimeSensor is contained within an inactive choice of an Switch, the TimeSensor sends events regardless of the Switch's state.

Constructor & Destructor Documentation

Switch ( const char *  name = ""  ) 

Construct a node with all its fields set to default value, which is equivalent to the code below:

  whichChoice = -1;

~Switch (  )  [virtual]

Virtual destructor, does nothing


Member Function Documentation

unsigned int nbFields (  )  const [inline, virtual]

Returns the number of fields (exposed or not) for this node type.

Implements Node.

wrl::Node::FieldHandle field ( const std::string &  n  )  [virtual]

Return a handle on the field named n of the node or a "unknown" typed handle if there is no such field. Valid names are:

Implements Node.

wrl::Node::FieldHandle field ( unsigned int  n  )  [virtual]

Return a handle on the i th field of the node or a "unknown" typed handle if there is no such node. Here is how i is related to fields:

Implements Node.

bool isSetToDefaultValue ( unsigned int  i  )  const [virtual]

Implements Node.

unsigned int nbEventsIn (  )  const [inline, virtual]

Returns the number of events in for this node type.

Implements Node.

wrl::Node::EventInHandle eventIn ( const std::string &  n  )  [virtual]

Return a handle on the event in named n of the node or a "unknown" typed handle if there is no such event. Valid names are:

Implements Node.

wrl::Node::EventInHandle eventIn ( unsigned int  n  )  [virtual]

Return a handle on the i th event in of the node or a "unknown" typed handle if there is no such node. emarks This class has no eventIn. This function is useful, with nbEventsIn() if you want to traverse all events in of a Node.

Implements Node.

unsigned int nbEventsOut (  )  const [inline, virtual]

Returns the number of events out for this node type.

Implements Node.

wrl::Node::EventOutHandle eventOut ( const std::string &  n  )  [virtual]

Return a handle on the event out named n of the node or a "unknown" typed handle if there is no such event. Valid names are:

Implements Node.

wrl::Node::EventOutHandle eventOut ( unsigned int  n  )  [virtual]

Return a handle on the i th event out of the node or a "unknown" typed handle if there is no such node. Here is how i is related to fields:

Implements Node.

const char * typeName (  )  const [inline, virtual]

Returns "Switch". Useful for printing.

Implements Node.

wrl::Node * duplicate (  )  const [virtual]

Returns a deep copy of this node, that is a fully independant node with all children (if any) also copied. This is mainly useful for instanciating protos.

Implements Node.

virtual Node* duplicate ( std::map< const Node *, Node * > &   )  const [virtual]

Implements Node.
