Use these extension methods to activate a pipe underlying the command. We can't keep it permanently activated because it is held on weak reference and can be collected at any time. Hence the newly created command will not be activated.

Presents callstacks for given allocation points.

This view model similar to IBacktraceAllocationsPresenter but desiged to be more general. Right now it is used for finalized object allocation callstack prsentation. In future, it is possible to re-factor instance backtraces and traffic backtraces.

Returns all types from tree root till specified node (including node itself). Meta-nodes with TypeId.Invalid are skipped. Returned list ordered from root downto node.

Similar to but returns formatted type names instead of type ids.

Sunburst part of dominator tree compound view model.

Gets the tree diagram source.

Gets the tree node size evaluator.

Gets the command for diagram item double click.

Gets the dominator tree compound view model.

Gets the sunburst core (central) node. By default is RootNode.

Gets or sets the sunburst selected node.

Actually, IDominatorTreeSunburstVm.SelectedNode and IDominatorTreeTreeVm.SelectedNode are the same nodes, but we need to distinguish who initiate selection change and for whom we need to send update. Otherwise we have a trouble with 'scroll to selected' functionality in tree list - it reacted on self change.

Whether node have children or not.

This property might change from true to false if children evaluated lazily.

Whether node is expanded or not. Can't be true if HasChildren is false.

Set of child nodes. Empty if none.

This property might change if children expanded asynchronously. The actual expansion is started only when enumeration is requested.
Use this property for children binding to TreeList control. The laziness is important in this case because control gets children for each visible node and checks returned collection on INotifyCollectionChanged without actual enumeration.

Sets to true and fires IHierarchyContainer.NodeExpandForced event.
This is a kind of workaround: the view (TreeList control) might ignore IsExpanded property changing if node out of visible scope, but in some cases we must ensure node expansion from vm-side. Use for such cases.

Must be called on UI thread.

Expands (builds) children for specified node. MUST BE called from UI thread.

Expanded children are filtered and sorted according to current criteria and comparision.

Method is asynchronous but node update performed on UI thread. When completed Expanded event is fired on UI thread.

The allocated bytes value counted over realtime statistics has some peculiarities:
* it's approximated value;
* it has minimal threshold.
Just to simplify WPF binding the already formatted (including all peculiarities) string is provided.

Objects of this type are exposed into WPF GUI part, so it implements to avoid memory leaks.

The first offset (character position) of the range, inclusive. A character at this index is included with the range.

The last offset (character position) of the range, non-inclusive. A character at this index is not included with the range and goes right after the range end. An end offset could point at the end of the document, in which case there's no character at this position.

Converts multiline highlighted string to "one-line" version replacing new line and carriage return with "\n" and "\r" strings correspondingly. Also trims it from the beginning of the first highlighted symbols. It could be split into two methods, but while it's not needed, it's implemented as one to reduce the number of allocations.

The number of symbol to keep left to the first highlight when trimming. The minimal length of the string to trimm, shorter string will not be trimmed. Guarantees that the original is returned in case no modifications needed: no trimming or character substitution.

Determines how many symbols should be trimmed left to ensure that the first highlight, if any, is visible.

The number of symbols to show left to highlight after ellipsis.
