namespace std _GLIBCXX_VISIBILITY

(

default

)

A standard container composed of unique keys (containing at most one of each key value) in which the elements' keys are the elements themselves.

Meets the requirements of a container, and unordered associative container

Parameters

Value	Type of key objects.
Hash	Hashing function object type, defaults to hash<Value>.
Pred	Predicate function object type, defaults to equal_to<Value>.
Alloc	Allocator type, defaults to allocator<Key>.

A standard container composed of equivalent keys (possibly containing multiple of each key value) in which the elements' keys are the elements themselves.

Meets the requirements of a container, and unordered associative container

Parameters

Value	Type of key objects.
Hash	Hashing function object type, defaults to hash<Value>.
Pred	Predicate function object type, defaults to equal_to<Value>.
Alloc	Allocator type, defaults to allocator<Key>.
