const

void cv::dnn::Dict::erase

(

const String &

key

)

Erase key from the dictionary.

const DictValue& cv::dnn::Dict::get

(

const String &

const

If the key in the dictionary then returns its value, else an error will be generated.

template<typename T >

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.

template<typename T >

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.

DictValue* cv::dnn::Dict::ptr

(

const String &

key

)

If the key in the dictionary then returns pointer to its value, else returns NULL.

const DictValue* cv::dnn::Dict::ptr

(

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.

template<typename T >

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.
