JetBrains.Common.Util.ViewModel

Represents cursor (aka y-axis) for multi-chart.

Represents set of charts with multiple y-values per each x-value.

Charts count (= count of y-values).

Gets chart identity by index. Used to chart view customization.

Tries to get y-values at specified x-value applying interpolation if needed. Might return extended content per y-value to be used in tool tip, for example. Returns false if x out of chart x-values.

Gets chart points filling provided . The must have length multiple of ( + 1).

Interface is optimized for getting points without any additional allocation.

Continues getting of chart points.

Fired when part of chart is changed or appended.

Used for incremental updates - charts count and chart's identities are not changed.

Fired when whole charts data is re-loaded.

Used for full updates - charts count and chart's identities might be changed also.

Represents now moment values for set of charts with multiple y-values per each x-value.

Charts count (= count of y-values).

Gets chart identity by index. Used to chart view customization.

Current X-value.

Gets current Y-values. The must have length equals to .

Fired when current values are changed.

Gets/sets the state of the associated UI toggle (ex. CheckBox). The return value is calculated based on the check state of all child FooViewModels. Setting this property to true or false will set all children to the same check state, and setting it to any value will cause the parent to verify its check state.

Revisited version of SimpleCommand and DelegateCommand. Uses instead of Dispatcher.

Consider to use revisited implementation.

The mixin interface for VM nodes which can be uniquely identified: e.g. by object address, type id and so on.

This interface intended for selection persist/restore machinery: both inside single app run and between separate runs.
Q. Why not Equals inside single run?
A. Because Equals has unclear semantic for VM node: e.g. differently highlighted title should be treated as equal or not?

This class is made for raising event manually. It is needed for sorting collection bound to TreeList control or some other changing of the collection.

Used to create a new instance of collection to force WPF refresh view state if the same instance is exposed WPF ignores raising event

This class is useful if you use some implementation of INotifyCollectionChanged like an and should expose where D inherits B. You cannot use IEnumerable.Cast" extension method because it returns an object of class does not inherit and does not linked with source collection.

Observable wrapper for read-only collection. Used in view models to prevent WPF collection binding leak.

Total Subtree Size

Null if Children a not initialized

Left Coordinate of Node

Represents tree structure as a plain list: Index Item ----------------- 0 Grandparent 1 Parent1 2 Child1 3 Child2 4 Parent2 5 Child3 6 Parent3 ...

Reloads the collection, expanding nodes if necessary.

Forces to reload children of given item. Uses to obtain item's expand state and children.

Compares item's children provided by with children currently presented in the list

True if children sequences are equal

Returns expand state of the item inside the collection. Returns true if item's children are presented in the list.

Removes all descendants of the item from the list

Inserts children of the item into the list and recursively expands children if needed. Uses to obtain item's expand state and children.

Returns parent of the item that is presented in the list

Returns level of the item. 0 for top-level items.

Top-level collection of items

Used to obtain children and expand state of the items

Implementation of IPlainTreeItemCollection optimized for deep trees.

Strongly typed SortState for using from code.

Untyped SortState is necessary to prevent generics in XAML.

The same as just to distinguish re-worked version.

Be careful, may affect performance

The re-worked sorter view-model adapted for typical dotMemory use case:
* it bound to ISettings to persist/restore sort state automatically;
* it does send first update only after restore;
* it exposes Comparison as data provider.

Provides color for sunburst nodes.

Returns sunburst sector color by given polar coordinates.

Provides data to SunburstDiagram control.

Core (central) node.

Gets view-model node wrapped to ISunburstNode.

The following events initiate sunburst animated transition (only one must be fired on CoreNode change):
* CoreNodeZoomedIn should be fired when new core is descendant of existing one; starts 'zoom-in' animation
* CoreNodeZoomedOut should be fired when new core is ancestor of existing one; starts 'zoom-out' animation
* CoreNodeFiltered should be fired when children of existing core has filtered; starts 'fade-out-in' animation
* CoreNodeMoved should be fired when new core is in different branch against existing one; starts 'twist-out-in' animation
* CoreNodeChanged should be fired if animation isn't needed

Sunburst color scheme based on HSB color space.

Defines the data source for a TreeDiagram control. This interface provides the necessary methods to retrieve hierarchical data and structure, which the control uses to construct and display its items.

Implementations of this interface should provide efficient access to the hierarchical data required by tree diagram controls. This includes methods for accessing individual nodes, the number of children for a given node, and notifying about updates in the data source.

Gets the root node of the hierarchical data structure.

Retrieves the child node at a specified index under a given parent node.

The parent node from which to retrieve the child. The index of the child to retrieve. The child node.

Gets the number of child nodes for a given parent node.

The parent node to count children for. The number of children.

Gets the root node of the hierarchical data structure.

Retrieves the child node at a specified index under a given parent node.

The parent node from which to retrieve the child. The index of the child to retrieve. The child node.

Gets the number of child nodes for a given parent node.

The parent node to count children for. The number of children.

Event to notify when the data source is updated

Sets the pixel color into 32bit bitmap. Bitmap must be locked before this operation
