Detailed Description

template<typename Key, typename Val>
class uhd::dict< Key, Val >

A templated dictionary class with a python-like interface.

Constructor & Destructor Documentation

dict() [1/2]

template<typename Key , typename Val >

uhd::dict< Key, Val >::dict

(

void

)

Create a new empty dictionary.

dict() [2/2]

template<typename Key , typename Val >

template<typename InputIterator >

uhd::dict< Key, Val >::dict	(	InputIterator	first,
		InputIterator	last
	)

Input iterator constructor: Makes boost::assign::map_list_of work.

Parameters

first	the begin iterator
last	the end iterator

Member Function Documentation

get() [1/2]

template<typename Key, typename Val>

const Val & uhd::dict< Key, Val >::get	(	const Key &	key,
		const Val &	other
	)		const

Get a value in the dict or default.

Parameters

key	the key to look for
other	use if key not found

Returns

the value or default

get() [2/2]

template<typename Key, typename Val>

const Val & uhd::dict< Key, Val >::get

(

const Key &

key

)

const

Get a value in the dict or throw.

Parameters

key	the key to look for

Returns

the value or default

has_key()

template<typename Key, typename Val >

bool uhd::dict< Key, Val >::has_key

(

const Key &

key

)

const

Does the dictionary contain this key?

Parameters

key	the key to look for

Returns

true if found

keys()

template<typename Key , typename Val >

std::vector< Key > uhd::dict< Key, Val >::keys

(

void

)

const

Get a list of the keys in this dict. Key order depends on insertion precedence.

Returns

vector of keys

operator!=()

template<typename Key, typename Val>

bool uhd::dict< Key, Val >::operator!=

(

const dict< Key, Val > &

other

)

const

Not equal operator for the dict type

Parameters

other

the dict being compared to this

Returns

whether or not the two dict's are not equal

operator==()

template<typename Key, typename Val>

bool uhd::dict< Key, Val >::operator==

(

const dict< Key, Val > &

other

)

const

Equals operator for the dict type

Parameters

other

the dict being compared to this

Returns

whether or not the two dict's are equal

operator[]() [1/2]

template<typename Key, typename Val >

const Val & uhd::dict< Key, Val >::operator[]

(

const Key &

key

)

const

Get a value for the given key if it exists. If the key is not found throw an error.

Parameters

key	the key to look for

Returns

the value at the key

Exceptions

an	exception when not found

operator[]() [2/2]

template<typename Key, typename Val >

Val & uhd::dict< Key, Val >::operator[]

(

const Key &

key

)

Set a value for the given key, however, in reality it really returns a reference which can be assigned to.

Parameters

key	the key to set to

Returns

a reference to the value

pop()

template<typename Key, typename Val >

Val uhd::dict< Key, Val >::pop

(

const Key &

key

)

Pop an item out of the dictionary.

Parameters

key	the item key

Returns

the value of the item

Exceptions

an	exception when not found

set()

template<typename Key, typename Val>

void uhd::dict< Key, Val >::set	(	const Key &	key,
		const Val &	val
	)

Set a value in the dict at the key.

Parameters

key	the key to set at
val	the value to set

size()

template<typename Key , typename Val >

std::size_t uhd::dict< Key, Val >::size

(

void

)

const

Get the number of elements in this dict.

Returns

the number of elements

update()

template<typename Key, typename Val>

void uhd::dict< Key, Val >::update	(	const dict< Key, Val > &	new_dict,
		bool	fail_on_conflict = true
	)

Update this dictionary with values from another.

Basically, this copies all the key/value pairs from new_dict into this dict. When the key is already present in the current dict, it either overwrites the current value (if fail_on_conflict is false) or it throws (if fail_on_conflict is true and the values differ).

With the exception of fail_on_conflict, this behaves analogously to Python's dict.update() method.

Parameters

new_dict	The arguments to copy.
fail_on_conflict	If true, throws.

Exceptions

uhd::value_error

vals()

template<typename Key , typename Val >

std::vector< Val > uhd::dict< Key, Val >::vals

(

void

)

const

Get a list of the values in this dict. Value order depends on insertion precedence.

Returns

vector of values
