Detailed Description

These methods relate to the statistics I/O interface.

Function Documentation

◆ addStat()

void gem5::statistics::Group::addStat ( statistics::Info * info )

Register a stat with this group.

This method is normally called automatically when a stat is instantiated.

Definition at line 109 of file group.cc.

References gem5::statistics::Group::addStat(), gem5::statistics::Group::mergedParent, and gem5::statistics::Group::stats.

◆ addStatGroup()

void gem5::statistics::Group::addStatGroup	(	const char *	name,
		Group *	block
	)

Add a stat block as a child of this block.

This method may only be called from a Group constructor or from regStats. It's typically only called explicitly from Python when setting up the SimObject hierarchy.

Definition at line 117 of file group.cc.

◆ getStatGroups()

const std::map< std::string, Group * > & gem5::statistics::Group::getStatGroups ( ) const

Get all child groups associated with this object.

◆ getStats()

const std::vector< Info * > & gem5::statistics::Group::getStats ( ) const

Get all stats associated with this object.

◆ Group() [2/3]

delete

◆ Group() [3/3]

gem5::statistics::Group::Group	(	Group *	parent,
		const char *	name = `nullptr`
	)

Construct a new statistics group.

The constructor takes two parameters, a parent and a name. The parent group should typically be specified. However, there are special cases where the parent group may be null. One such special case is SimObjects where the Python code performs late binding of the group parent.

If the name parameter is NULL, the group gets merged into the parent group instead of creating a sub-group. Stats belonging to a merged group behave as if they have been added directly to the parent group.

Parameters

parent	Parent group to associate this object to.
name	Name of this group, can be NULL to merge this group with the parent group.

Definition at line 54 of file group.cc.

References gem5::statistics::Group::addStatGroup(), gem5::statistics::Group::mergeStatGroup(), and name().

◆ operator=()

Group& gem5::statistics::Group::operator= ( const Group & )

delete

◆ preDumpStats()

void gem5::statistics::Group::preDumpStats ( )

virtual

Callback before stats are dumped.

This can be overridden by objects that need to perform calculations in addition to the capabiltiies implemented in the stat framework.

Reimplemented in gem5::PowerState::PowerStateStats, gem5::memory::DRAMInterface::RankStats, and gem5::BaseTags::BaseTagStats.

Definition at line 99 of file group.cc.

◆ regStats()

void gem5::statistics::Group::regStats ( )

virtual

Callback to set stat parameters.

This callback is typically used for complex stats (e.g., distributions) that need parameters in addition to a name and a description. Stat names and descriptions should typically be set from the constructor usingo from the constructor using the ADD_STAT macro.
