Function Documentation

namespace std _GLIBCXX_VISIBILITY ( default  )

A standard container composed of unique keys (containing at most one of each key value) that associates values of another type with the keys.

Meets the requirements of a container, and unordered associative container

Parameters
KeyType of key objects.
TpType of mapped objects.
HashHashing function object type, defaults to hash<Value>.
PredPredicate function object type, defaults to equal_to<Value>.
AllocAllocator type, defaults to allocator<Key>.

The resulting value type of the container is std::pair<const Key, Tp>.

A standard container composed of equivalent keys (possibly containing multiple of each key value) that associates values of another type with the keys.

Meets the requirements of a container, and unordered associative container

Parameters
KeyType of key objects.
TpType of mapped objects.
HashHashing function object type, defaults to hash<Value>.
PredPredicate function object type, defaults to equal_to<Value>.
AllocAllocator type, defaults to allocator<Key>.

The resulting value type of the container is std::pair<const Key, Tp>.
