Detailed Description

Abstract base class for VRML97 node implementations.

AbstractBase encapsulates the mechanisms for field access and mutation, event dispatch, and eventOut access.

Constructor & Destructor Documentation

~AbstractBase (    )  throw () [pure virtual]

Destructor.

AbstractBase (  const NodeType &    nodeType, const ScopePtr &    scope )  [protected]

Constructor. Parameters: nodeType  the NodeType associated with this node. scope  the Scope to which the node belongs.

Member Function Documentation

const FieldValue & getEventOutImpl (  const std::string &    id )  const throw (UnsupportedInterface) [private, virtual]

Get an eventOut value for a node. Parameters: id  an eventOut name. Exceptions: UnsupportedInterface  if the node has no eventOut id. Implements Node.

const FieldValue & getFieldImpl (  const std::string &    id )  const throw (UnsupportedInterface) [private, virtual]

Get a field value for a node. Parameters: id  a field name. Exceptions: UnsupportedInterface  if the node has no field id. Implements Node.

void processEventImpl (  const std::string &    id, const FieldValue &    value, double    timestamp )  throw (UnsupportedInterface, std::bad_cast, std::bad_alloc) [private, virtual]

Process an event. Parameters: id  an eventIn name. value  a FieldValue. timestamp  the current time. Exceptions: UnsupportedInterface  if the node has no eventIn id. std::bad_cast  if value is not the correct type. std::bad_alloc  if memory allocation fails. Precondition: value must be of the correct type. Implements Node.

void setFieldImpl (  const std::string &    id, const FieldValue &    value )  throw (UnsupportedInterface, std::bad_cast, std::bad_alloc) [private, virtual]

Set a field value for a node. Parameters: id  a field name. value  a FieldValue. Exceptions: UnsupportedInterface  if the node has no field id. std::bad_cast  if value is not the correct type. std::bad_alloc  if memory allocation fails. Precondition: value must be of the correct type. Implements Node.
