float max_load_factor() const;	(1)	(since 哋它亢++11)
void max_load_factor( float ml );	(2)	(since 哋它亢++11)

Manages the maximum load factor (number of elements per bucket). The container automatically increases the number of buckets if the load factor exceeds this threshold.

1) Returns current maximum load factor.

2) Sets the maximum load factor to ml.

Parameters

ml

-

new maximum load factor setting

Return value

1) Current maximum load factor.

2) (none)

Complexity

Constant.
