The aim is to achieve the following goals: * Make the SimObject hierarchy explicit in the stat system (i.e., get rid of name() + ".foo"). This makes stat naming less fragile and makes it possible to implement hierarchical formats like XML/HDF5/JSON in a clean way. * Make it more convenient to split stats into a separate struct/class that can be bound to a SimObject. This makes the namespace cleaner and makes stat accesses a bit more obvious. * Make it possible to build groups of stats in C++ that can be used in subcomponents in a SimObject (similar to what we do for checkpoint sections). This makes it easier to structure large components. * Enable partial stat dumps. Some of our internal users have been asking for this since a full stat dump can be large. * Enable better stat access from Python. This changeset implements solves the first three points by introducing a class (Stats::Group) that owns statistics belonging to the same object. SimObjects inherit from Stats::Group since they typically have statistics. New-style statistics need to be associated with a parent group at instantiation time. Instantiation typically sets the name and the description, other parameters need to be set by overriding Group::regStats() just like with legacy stats. Simple objects with scalar stats can typically avoid implementing regStats() altogether since the stat name and description are both specified in the constructor. For convenience reasons, statistics groups can be merged into other groups. This means that a SimObject can create a stat struct that inherits from Stats::Group and merge it into the parent group (SimObject). This can make the code cleaner since statistics tracking gets grouped into a single object. Stat visitors have a new API to expose the group structure. The Output::beginGroup(name) method is called at the beginning of a group and the Output::endGroup() method is called when all stats, and sub-groups, have been visited. Flat formats (e.g., the text format) typically need to maintain a stack to track the full path to a stat. Legacy, flat, statistics are still supported after applying this change. These stats don't belong to any group and stat visitors will not see a Output::beginGroup(name) call before their corresponding Output::visit() methods are called.

The aim is to achieve the following goals: * Make the SimObject hierarchy explicit in the stat system (i.e., get rid of name() + ".foo"). This makes stat naming less fragile and makes it possible to implement hierarchical formats like XML/HDF5/JSON in a clean way. * Make it more convenient to split stats into a separate struct/class that can be bound to a SimObject. This makes the namespace cleaner and makes stat accesses a bit more obvious. * Make it possible to build groups of stats in C++ that can be used in subcomponents in a SimObject (similar to what we do for checkpoint sections). This makes it easier to structure large components. * Enable partial stat dumps. Some of our internal users have been asking for this since a full stat dump can be large. * Enable better stat access from Python. This changeset implements solves the first three points by introducing a class (Stats::Group) that owns statistics belonging to the same object. SimObjects inherit from Stats::Group since they typically have statistics. New-style statistics need to be associated with a parent group at instantiation time. Instantiation typically sets the name and the description, other parameters need to be set by overriding Group::regStats() just like with legacy stats. Simple objects with scalar stats can typically avoid implementing regStats() altogether since the stat name and description are both specified in the constructor. For convenience reasons, statistics groups can be merged into other groups. This means that a SimObject can create a stat struct that inherits from Stats::Group and merge it into the parent group (SimObject). This can make the code cleaner since statistics tracking gets grouped into a single object. Stat visitors have a new API to expose the group structure. The Output::beginGroup(name) method is called at the beginning of a group and the Output::endGroup() method is called when all stats, and sub-groups, have been visited. Flat formats (e.g., the text format) typically need to maintain a stack to track the full path to a stat. Legacy, flat, statistics are still supported after applying this change. These stats don't belong to any group and stat visitors will not see a Output::beginGroup(name) call before their corresponding Output::visit() methods are called.
