Tree node extensions are typically instantiated on-demand for best performance (you have to explicitly ask for an extension by its name, or it won't be created) - so note that calling this method will trigger the creation of all this node's extensions.

Protected Member Functions inherited from sparta::NotificationSourceBase
bool	canGenerateNotification_ (const std::type_info &tinfo, const std::string *id, const std::string *&match) const override
	Implements TreeNode::canGenerateNotification. Node subclasses which will post notifications must implement this method and only post notifications with types and names that would cause this function to return true.

std::pair< uint32_t, std::string >	recursGetDeepestMatchingPath_ (const std::string &path, size_t name_pos) const
	Finds the deepest node path mathing the input path. Implements getDeepestMatchingPath.
void	setExpectedParent_ (const TreeNode *parent)
	Tracks a node as an expected parent without actually adding this node as a child. This is used almost exclusively for printing error messages which include a device-tree location BEFORE actually inserting this node into the device tree since node construction can fail.
void	enterFinalizing_ ()
	Recursively enter TREE_FINALIZING phase.
void	finalizeTree_ ()
	Recursively create resources based on tree configuration. enter_finalize_ should be invoked after this method successfully completes for an entire tree. Finalizes in the order of construction.
void	validateTree_ ()
	Iterates the finalized tree and validates each node (e.g. ensures statistics can be evaluated)
void	enterFinalized_ ()
	Recursively enter TREE_FINALIZED phase.
void	enterConfig_ () noexcept
	Recursively enter TREE_CONFIGURING phase.
void	bindTreeEarly_ ()
	Recursively invoke TreeNode::onBindTreeEarly_ and Resource::onBindTreeEarly_ (in that order for each node)

	Recursively invoke TreeNode::onBindTreeEarly_ and Resource::onBindTreeLate_ (in that order for each node)
void	simulationTerminating_ ()
	Hook to allow simulation resources to clean-up before simulation is ended.
void	validatePostRun_ (const PostRunValidationInfo &info) const
	Hook to check the state of the simulator post-run and throw exceptions if something is incorrect.
void	dumpDebugContent_ (std::ostream &out) const noexcept
	Allows resources to write out detailed textual debugging information about the node. This is typically called by a simulator when shutting down due to an exception (or depending on simulator config). However, it could also be called at other times.
void	enterTeardown_ () noexcept
	Recursively enter TREE_TEARDOWN phase while alerting nodes through onEnteringTeardown_ and alterting Resources through Resource::onStartingTeardown_. Nodes already in TREE_TEARDOWN phase will not be alerted (neither will their associated Resources). All nodes are visited regardless of their parent's phase.
void	verifyUniqueChildIdentifier_ (const std::string &ident, bool ignore_group_collision=false)
	Verifies that the given identifier is unique for all children of this node by comparing against names, groups, and aliases. Throws SpartaException if not unique.
void	removeChildForTeardown_ (TreeNode *child)
	"Removes" the given child by invoking onDestroyingChild_ then removing this child from the children_ list
void	removeFromParentForTeardown_ (TreeNode *parent)
	Protected Wrapper for getParent()->removeChildForTeardown_ which allows subclases of TreeNode to indirectly invoke removeChildForTeardown_ with themselves as the argument.
void	detachFromParent_ ()
	Removes a node from its parent with the expectation this node will be immediately destroyed (i.e. is an xvalue)
void	detachFromChildren_ ()
	Removes a node from its children with the expectation this node will be immediately destroyed (i.e. is an xvalue)
bool	areParametersLocked_ () const
	This method informs whether the tree is past the lockdown phase for all LOCKED and HIDDEN parameters. Modifying LOCKED and HIDDEN parameters after this phase is disallowed. Tree can be locked down during TREE_BUILDING phase or TREE_CONFIGURING phase. During TREE_FINALIZING phase, all parameters are locked down as is.

DelegateVector::iterator	findDelegate_ (DelegateVector &dvec, T *obj, const std::string &target_name)
	Finds a delegate associated with the given type T, object pointer, DataT, and TMethod within a DelevateVector. The intent of this function is to help see if a delegate is already registered with a calback by checking all known information associated with that callback against the input arguments.

Detailed Description

template<typename NotificationDataT>
class sparta::MirrorNotificationSource< NotificationDataT >

essentially a pass through notification source that is a placeholder in a shadow tree.

This is a placeholder to represent a potentially private notification source or many private notification sources originating from this location in the tree.

Member Function Documentation

addLink()

template<typename NotificationDataT >

void sparta::MirrorNotificationSource< NotificationDataT >::addLink ( TreeNode *  node, const std::string &  label  )

inlinefinaloverridevirtual

Given a node in potentially private treenodes, bind to all notification sources under it that match our type and name.

The node may actually be the concrete NotificationSource or it can be a higher node up.

The idea is that a single mirror could reflect notifications of same type/name coming from multiple sources under a common node. So we could bind to the node above all of those sources to achieve that.

Reimplemented from sparta::TreeNode.
