Detailed Description

The Base Node class. All nodes to be inserted in a network must derive from this class. It contains the proper initializations for the connectivity of the nodes.

string name

[protected]

Node's name

vector<NodeInput> inputs

[protected]

Node's inputs

vector<string> outputNames

[protected]

Node's outputs

ParameterSet parameters

[protected]

Parameters given to the node at construction time

UINode * uinode

[protected]

Corresponding UINode

void  connectToNode (unsigned int in, Node *inputNode, unsigned int out)

[protected virtual]

Connect an input node using numeric (integer) input/output names

int  addOutput (const string &outputName)

[protected virtual]

Adding an output to a node

int  addInput (const string &inputName)

[protected virtual]

Adding an input to a node

vector<NodeInput>&  getInputs ()

[protected virtual]

Returns the inputs vector

 Node (string nodeName, const ParameterSet &params)

Constructor, takes the name of the node and a set of parameters

~ Node ()

[virtual]

Destructor

ObjectRef  getOutput (int output_id, int count)

[pure virtual]

Ask for the node's output which ID (number) is output_id and for the 'count' iteration

ObjectRef  getOutputNamed (const string &outputName, int count)

[virtual]

Ask for the node's output (named) and for the count iteration

void  connectToNode (string in, Node *inputNode, string out)

[virtual]

Connect an input node using symbolic (strings) input/output names

void  initialize ()

[virtual]

Initialize a node

bool  hasOutput (int output_id)

[const virtual]

Checks whether node really has a certain output

ObjectRef  getInput (int inputID, int count)

void  stop ()

[virtual]

Asks the node to stop what it is doing to allow processing termination

void  cleanupNotify ()

[virtual]

Notify the node that is will be destroyed shortly

void  reset ()

[virtual]

Resets the node internal values and buffers

string  getName ()

Returns the node name

void  request (int outputID, const ParameterSet &req)

[virtual]

Standard request-passing method between nodes during initialization

void  verifyConnect ()

[virtual]

Verify input connections for the node

void  printOn (ostream &out=cout)

[const]

A node can print itself

Reimplemented from Object.

void  setUINode (UINode *_uinode)

int  addFactory (const string &factoryName, _NodeFactory* const factory)

[static]

Adding a factory into the static dictionary

_NodeFactory*  getFactoryNamed (const string &name)

[static]

The factory lookup function

 Node ()

[protected]

int  translateInput (string inputName)

[protected virtual]

symbolic to numeric translation for input names

int  translateOutput (string inputName)

[protected virtual]

symbolic to numeric translation for output names

void  rt_assert (bool cond, string message="", char *_file="unknown", int _line=0)

[protected virtual]

Run-time assertions

void  construct_assert (bool cond, string message="", char *_file="unknown", int _line=0)

[protected virtual]
