Member Function Documentation

template<class Key, class HashFcn = boost::hash< Key >>

void moost::io::map_store< Key, HashFcn >::alloc	(	boost::scoped_ptr< variable_store::scoped_block > &	p,
		const Key &	key,
		size_t	block_size
	)		[inline, private]

allocs a scoped_block for a new key doesn't support reallocing on an existing key, maybe in the future

Here is the caller graph for this function:

template<class Key, class HashFcn = boost::hash< Key >>

void moost::io::map_store< Key, HashFcn >::free

(

const Key &

key

)

[inline, private]

frees a key

Definition at line 104 of file map_store.hpp.

template<class Key, class HashFcn = boost::hash< Key >>

void moost::io::map_store< Key, HashFcn >::get	(	boost::scoped_ptr< variable_store::scoped_block > &	p,
		const Key &	key
	)		[inline, private]

gets a scoped_block given a key, or leaves empty if the key is not found

Definition at line 73 of file map_store.hpp.

Here is the caller graph for this function:

template<class Key, class HashFcn = boost::hash< Key >>

void moost::io::map_store< Key, HashFcn >::set_deleted_key

(

const Key &

key

)

[inline]

If you're going to delete keys, you must specify a deleted key that will never be used as a real key.
