Member Typedef Documentation

◆ KeyValueStore

using ns3::EnvironmentVariable::Dictionary::KeyValueStore = std::unordered_map<std::string, std::string>

Key, value store type.

Constructor & Destructor Documentation

◆ Dictionary()

ns3::EnvironmentVariable::Dictionary::Dictionary ( const std::string &  envvar,
const std::string &  delim = ";" 
)

Constructor.

Parse an environment variable containing keys and optional values.

Keys in the environment variable are separated by the delim character. Keys may be assigned values by following the key with the = character; any remaining text up to the next delimiter will be taken as the value. If no = is given the enpty string will be stored as the value.

Parameters
[in]envvarThe environment variable.
[in]delimThe delimiter between key,value pairs.
