Detailed Description

template<typename valT>
class SST::Shared::SharedSet< valT >

SharedSet class.

The class is templated to allow for an array of any non-pointer type. The type must be serializable.

Member Function Documentation

◆ count()

template<typename valT>
size_t SST::Shared::SharedSet< valT >::count ( const valT &  k) const
inline

Counts elements with a specific value.

Becuase this is not a multiset, it will either return 1 or 0.

Returns
Count of elements with specified value

◆ empty()

template<typename valT>
bool SST::Shared::SharedSet< valT >::empty ( ) const
inline

Tests if the set is empty.

Returns
true if set is empty, false otherwise

◆ find()

template<typename valT>
const_iterator SST::Shared::SharedSet< valT >::find ( const valT &  value) const
inline

Searches the SharedSet for an element equivalent to value and returns a const iterator to it if found, otherwise it returns an iterator to SharedSet::end.

Parameters
valuevalue to search for

NOTE: This function does not use a mutex, so it is possible to get invalid results if another thread is simulateously writing to the set. However, after the init() phase of simulation is complete (in setup() and beyond), this is always a safe operation. If reading during init() and you can't guarantee that all elements have already written all elements to the SharedSet, use mutex_find() to guarantee thread safety.

Returns
read-only iterator to data referenced by value

◆ initialize()

template<typename valT>
int SST::Shared::SharedSet< valT >::initialize ( const std::string &  obj_name,
verify_type  v_type 
)
inline

Initialize the SharedSet.

Parameters
obj_nameName of the object. This name is how the object is uniquely identified across ranks.
verify_modeSpecifies how multiply written data should be verified. Since the underlying set knows if the data has already been written, FE_VERIFY and INIT_VERIFY simply use this built-in mechanism to know when an item has previously been written. When these modes are enabled, multiply written data must match what was written before. When NO_VERIFY is passed, no verification will occur. This is mostly useful when you can guarantee that multiple elements won't write the same value and you want to do in-place modifications as you initialize. VERIFY_UNINITIALIZED is a reserved value and should not be passed.
Returns
returns the number of instances that have intialized themselve before this instance on this MPI rank.

◆ insert()

template<typename valT>
void SST::Shared::SharedSet< valT >::insert ( const valT &  value)
inline

Insert data to the set.

This function is thread-safe, as a mutex is used to ensure only one insert at a time.

Parameters
valvalue of the insert

◆ isFullyPublished()

template<typename valT>
bool SST::Shared::SharedSet< valT >::isFullyPublished ( )
inline

Check whether all instances of this SharedSet have called publish().

NOTE: Is is possible that this could return true one round, but false the next if a new instance of the SharedSet was initialized but not published after the last call.

◆ mutex_find()

template<typename valT>
const valT& SST::Shared::SharedSet< valT >::mutex_find ( const valT &  value) const
inline

Searches the SharedSet for an element equivalent to value and returns a const iterator to it if found, otherwise it returns an iterator to SharedSet::end.

This version of find is always thread safe (

See also
find()).
Parameters
valuevalue to search for
Returns
read-only iterator to data reference by value

◆ publish()

template<typename valT>
void SST::Shared::SharedSet< valT >::publish ( )
inline

Indicate that the calling element has written all the data it plans to write.

Writing to the set through this instance after publish() is called will create an error.

◆ size()

template<typename valT>
size_t SST::Shared::SharedSet< valT >::size ( ) const
inline

Get the size of the set.

Returns
size of the set
