Member Function Documentation

getChangeSet()

template<typename T>

virtual SharedObjectChangeSet* SST::Shared::SharedArray< T >::Data::getChangeSet ( )

inlineoverridevirtual

Gets the changeset for this data on this rank.

This is called by the core when exchanging and merging data

Implements SST::Shared::SharedObjectData.

resetChangeSet()

template<typename T>

virtual void SST::Shared::SharedArray< T >::Data::resetChangeSet ( )

inlineoverridevirtual

Resets the changeset for this data on this rank.

This is called by the core when exchanging and merging data

Implements SST::Shared::SharedObjectData.

setSize()

template<typename T>

void SST::Shared::SharedArray< T >::Data::setSize ( size_t  size, const T &  init_data, verify_type  v_type  )

inline

Set the size of the array.

An element can only write up to the current size (reading or writing beyond the size will create undefined behavior). However, an element can put in the size it needs for it's writes and it will end up being the largest size requested. We use a vector underneatch the covers to manage the memory/copying of data.
