)
inline

Append a list to another list.

Parameters
listthe list on which the other list will be appended

Definition at line 398 of file UStl.h.

template<class V >
bool uContains ( const std::list< V > &  list,
const V &  value 
)
inline

Check if the list contains the specified value.

Parameters
listthe list
valuethe value
Returns
true if the value is found in the list, otherwise false

Definition at line 327 of file UStl.h.

template<class K , class V >
bool uContains ( const std::map< K, V > &  map,
const K &  key 
)
inline

Check if the map contains the specified key.

Parameters
mapthe map
keythe key
Returns
true if the value is found in the map, otherwise false

Definition at line 339 of file UStl.h.

template<class K , class V >
bool uContains ( const std::multimap< K, V > &  map,
const K &  key 
)
inline

Check if the multimap contains the specified key.

Parameters
mapthe map
keythe key

template<class V >
int uIndexOf ( const std::vector< V > &  list,

Get the index in the list of the specified value. S negative index is returned if the value is not found.

Parameters
listthe list
valuethe value
Returns
the index of the value in the list

template<class K , class V >
void uInsert ( std::map< K, V > &  map,
