Smart pointer class similar to boost::intrusive_ptr.
Definition: ptr.h:74
std::string m_fileName
Name of the input file.
void SetFileType(const std::string fileType)
Sets the input file type.
Ptr< TopologyReader > m_inputModel
Smart pointer to the actual topology model.
Ptr< TopologyReader > GetTopologyReader()
Gets a Ptr<TopologyReader> to the actual TopologyReader.
void SetFileName(const std::string fileName)
Sets the input file name.
std::string m_fileType
Type of the input file (e.g., "Inet", "Orbis", etc.).
#define NS_ASSERT_MSG(condition, message)
At runtime, in debugging builds, if this condition is not true, the program prints the message to out...
Definition: assert.h:88
#define NS_LOG_COMPONENT_DEFINE(name)
Define a Log component with a specific name.
Definition: log.h:205
#define NS_LOG_INFO(msg)
Use NS_LOG to output a message of level LOG_INFO.
