Member Function Documentation

add()

template<typename Key >

void precice::utils::MultiLock< Key >::add ( Key name, bool state )

inline

Adds a lock with a given state.

Adding an already existent lock does nothing.

Parameters

[in]	name	the name of the lock
[in]	state	the initial state of the lock

Definition at line 41 of file MultiLock.hpp.

check()

template<typename Key >

template<typename K >

bool precice::utils::MultiLock< Key >::check ( const K & name ) const

inline

Checks the status of a lock.

Parameters

[in]

name

the name of the lock to check

Returns

whether the lock is locked

Definition at line 105 of file MultiLock.hpp.

checkAll()

template<typename Key >

bool precice::utils::MultiLock< Key >::checkAll ( ) const

inlinenoexcept

Checks whether all locks are locked.

Definition at line 116 of file MultiLock.hpp.

Here is the call graph for this function:

clear()

template<typename Key >

void precice::utils::MultiLock< Key >::clear ( )

inlinenoexcept

Removes all known locks.

Definition at line 93 of file MultiLock.hpp.

contains()

template<typename Key >

template<typename K >

bool precice::utils::MultiLock< Key >::contains ( const K & name ) const

inlinenoexcept

Checks whether a lock is known.

Parameters

[in]

name

the name to check

Returns

whether the name is a known lock

Definition at line 131 of file MultiLock.hpp.

countLocked()

template<typename Key >

size_t precice::utils::MultiLock< Key >::countLocked ( ) const

inline

Returns the count of locked locks.

Definition at line 143 of file MultiLock.hpp.

Here is the call graph for this function:

countUnlocked()

template<typename Key >

size_t precice::utils::MultiLock< Key >::countUnlocked ( ) const

inline

Returns the count of unlocked locks.

Definition at line 149 of file MultiLock.hpp.

Here is the call graph for this function:

lock()

template<typename Key >

template<typename K >

void precice::utils::MultiLock< Key >::lock ( const K & name )

inline

Locks a given lock.

Parameters
