Detailed Description

collection of actions

collection of actions calls contains homogeneous actions operating on different types all collected actions have the same name and should have the same functionality

Definition at line 113 of file hyper_graph_action.h.

Constructor & Destructor Documentation

g2o::HyperGraphElementActionCollection::HyperGraphElementActionCollection

(

const std::string &

name_

)

constructor. name_ is the name of the action e.g.draw).

Definition at line 88 of file hyper_graph_action.cpp.

  {
    _name = name_;
  }

g2o::HyperGraphElementActionCollection::~HyperGraphElementActionCollection ( )

destructor: it deletes all actions in the pool.

bool g2o::HyperGraphElementActionCollection::registerAction

(

inserts an action in the pool. The action should have the same name of the container. returns false on failure (the container has a different name than the action);
