std::ostream & | operator<< (std::ostream &stream, const Dict &dict) |
This class implements name-value dictionary, values are instances of DictValue.
If the key
in the dictionary then returns its value, else an error will be generated.
T cv::dnn::Dict::get | ( | const String & | key | ) | const |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
T cv::dnn::Dict::get | ( | const String & | key, |
const T & | defaultValue | ||
) | const |
If the key
in the dictionary then returns its value, else returns defaultValue
.
bool cv::dnn::Dict::has | ( | const String & | key | ) | const |
Checks a presence of the key
in the dictionary.
If the key
in the dictionary then returns pointer to its value, else returns NULL.
const T& cv::dnn::Dict::set | ( | const String & | key, |
const T & | value | ||
) |
Sets new value
for the key
, or adds new key-value pair into the dictionary.
