This class implements name-value dictionary, values are instances of DictValue.
void cv::dnn::Dict::erase | ( | const String & | key | ) |
Erase key
from the dictionary.
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.
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
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.
