Member Data Documentation

m_accessor

std::unique_ptr<ISelectionWriteAccessor> CP::SysWriteSelectionHandle::m_accessor

private

the accessor we use

Definition at line 107 of file SysWriteSelectionHandle.h.

m_msg

std::function<MsgStream& ()> asg::AsgMessagingForward::m_msg

privateinherited

the message stream we use

This used to be a simple pointer to the MsgStream itself, but in AthenaMT the actual object used is local to the thread. So instead of pointing to it directly we are now using a function to look it up, which will get the thread-local object.

Definition at line 77 of file AsgMessagingForward.h.

m_objectHandle

const ISysHandleBase* CP::SysWriteSelectionHandle::m_objectHandle {nullptr}

private

the object handle we use

Definition at line 103 of file SysWriteSelectionHandle.h.

{nullptr};

m_selection

std::string CP::SysWriteSelectionHandle::m_selection

private

the selection we use

Definition at line 99 of file SysWriteSelectionHandle.h.
