What is counted. Each counter names, in its documentation, the function that counts it.

Variants

PropertyChangesRaised = 0

FerroObject::raise_property_changed: every notification built and passed to the on_property_changed chain of the class.

PropertyChangesEffective = 1

FerroObject::raise_property_changed: the ones of an effective value, which go on to the handlers of the property and the listeners of the object.

PropertyChangesWithPropertyHandlers = 2

PropertyChangedObservable::notify: the property has at least one handler (the class handlers and the subscriptions to the property).

PropertyChangesWithObjectListeners = 3

FerroObject::raise_property_changed: the object has at least one listener of its property changes.

InheritanceAncestorChanges = 4

ValueStore::set_inheritance_parent: the inheritance ancestor of an object changed.

InheritedValuesCompared = 5

ValueStore::set_inheritance_parent: the inherited properties of the old and the new ancestor chain that were paired.

InheritedValuesDiffering = 6

ValueStore::set_inheritance_parent: the ones whose old and new value differ, each of which starts a walk of the subtree.

InheritedValueWalkVisits = 7

ValueStore::inherited_value_changed: the objects such a walk reaches (the object itself and its inheritance descendants, once per property).

LogicalTreeAttachments = 8

StyledElement::on_attached_to_logical_tree_core: an element that was not in a logical tree enters one.

LogicalTreeDetachments = 9

StyledElement::on_detached_from_logical_tree_core: an element leaves its logical tree.

ImplicitThemeLookups = 10

StyledElement::get_effective_theme: the implicit theme was not known and was looked up as a resource.

StyleHostsWalked = 11

StyledElement::apply_styles: a style host between the element and the root was asked for its styles.

StylesEvaluated = 12

Style::try_attach_checked and ContainerQuery::try_attach_checked: a style with setters (a query with children) was matched against an element.

StylesMatched = 13

The same functions: the selector (the query) matched and the style was instanced on the element.

ControlThemesEvaluated = 14

ControlTheme::try_attach_checked: a control theme was tested against the style key of an element.

ControlThemesMatched = 15

ControlTheme::try_attach_checked: it applies and was instanced.

StyleInstancesAttached = 16

StyleBase::try_attach_instance: a style instance was added to the value store of an element.

StyleInstancesCreated = 17

StyleBase::try_attach_instance: the instance was built (its setters instanced) instead of the shared instance of the style being taken.

ResourceLookups = 18

IResourceHost::try_find_resource: a lookup up the logical tree.

ResourceHostsProbed = 19

IResourceHost::try_find_resource: the hosts such a lookup asked (try_get_resource of the host and of each styling parent).

BindingsInstanced = 20

FerroObject::bind_binding_with_anchor: a binding was instanced on a property of an object.

BindingExpressionsCreated = 21

UntypedBindingExpressionBase::new and TypedBindingExpression::new: a binding expression was created (by a binding, a setter, a template binding or a dynamic resource).

TemplateBindingExpressionsCreated = 22

TemplateBindingExpression::new.

DynamicResourceExpressionsCreated = 23

DynamicResourceExpression::new (the XAML runtime library).

BindingValuesPublished = 24

UntypedBindingExpressionBase::publish_value of a running expression and TypedBindingExpression::publish_value.

TextLayoutsCreated = 25

TextLayout::from_text_source.

TextLinesFormatted = 26

TextFormatterImpl::format_line_with_cache: a line was asked for.

TextRunCacheHits = 27

TextFormatterImpl::format_line_with_cache: the shaped runs of the line came from the text run cache.

TextRunCacheMisses = 28

TextFormatterImpl::format_line_with_cache: a cache was given, did not hold the line, and the shaped runs were added to it.

TextRunsShaped = 29

TextShaper::shape_text: a run was shaped by the platform shaper.

ContainersRecycled = 30

VirtualizingStackPanel::recycle_element: a container left the viewport, was cleared and went to the recycle pool.

ContainersReused = 31

VirtualizingStackPanel::get_recycled_element: a container of the pool was prepared for another item.

ContainersCreated = 32

VirtualizingStackPanel::create_element: a container was created.

ContentPresenterChildrenReplaced = 33

ContentPresenter::update_child_with: the child of a content presenter was replaced by another control or removed.
