Detailed Description

This class implements name-value dictionary, values are instances of DictValue.

Member Function Documentation

◆ begin()

std::map<String, DictValue>::const_iterator cv::dnn::Dict::begin ( ) const

◆ end()

std::map<String, DictValue>::const_iterator cv::dnn::Dict::end ( ) const

◆ erase()

void cv::dnn::Dict::erase ( const String key)

Erase key from the dictionary.

◆ get() [1/3]

const DictValue& cv::dnn::Dict::get ( const String key) const

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

◆ get() [2/3]

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.

◆ get() [3/3]

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.

◆ has()

bool cv::dnn::Dict::has ( const String key) const

Checks a presence of the key in the dictionary.

◆ ptr() [1/2]

DictValue* cv::dnn::Dict::ptr ( const String key)

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

◆ ptr() [2/2]

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.

◆ set()

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.
