Properties
| ActualSelection |
Gets the actual selection. (Inherited from SelectionState) |
| CoercedSelection |
We need to return an empty collection here to cause a coercion failure. This is a bit odd, but necessary given implementation of SelectionState.IsCoercionFailure. |
| CoercedSelectionCache |
cache for the coerced selection (Inherited from SelectionState) |
| CoercedSelectionModelElements |
It is possible for the CoercedSelection to include Pels and Mels which are This method returns a list that replaces the Pels in the coerced selection with their associated Mels, plus any mels from the coerced selection that did not have pels. (Inherited from SelectionState) |
| CoercedSelectionPresentationElements |
It is possible for the CoercedSelection to include Pels and Mels which are This method returns a collection which excludes any Mels. (Inherited from SelectionState) |
| CoercionCompliantSelection |
Returns the list of selected objects which comply with the coercion rules. If the selection is coercable, then the coerced selection will be returned; if there is a coercion failure the list will be empty. If there are no coercion rules (!IsCoercable), then the actual selection is returned. (Inherited from SelectionState) |
| HasCoercion |
Determines if the selection has a valid coercion. (Inherited from SelectionState) |
| Instance |
Singleton EmptySelection instance |
| IsActualSelectionMixed |
True if all selected objects in the actual selection are of the same type. (Inherited from SelectionState) |
| IsCoercedSelectionMixed |
True if all selected objects in the coerced selection are of the same type. (Inherited from SelectionState) |
| IsCoercible |
Determines if the actual selection can be coerced. Togegher IsCoercible and IsCoercionFailure distinguish between coercion failure, and no coercion available. (Inherited from SelectionState) |
| IsCoercionFailure |
Togegher IsCoercible and IsCoercionFailure distinguish between coercion failure, and no coercion available. (Inherited from SelectionState) |
Methods
| CacheCoercedSelection(ICollection) |
Cache the specified collection. (Inherited from SelectionState) |
| IdentifyCommandsToBeFilteredOutForMultipleSelection(CommandIdCollection) |
Override to identify the commands which are not valid in a single selection scenario, for this selection state. (Inherited from SelectionState) |
| IdentifyCommandsToBeFilteredOutForSingleSelection(CommandIdCollection) |
Override to identify the commands which are not valid in a single selection scenario, for this selection state. (Inherited from SelectionState) |
| Initialize(ICollection) |
specifies the actual selection to operate upon. (Inherited from SelectionState) |
| IsApplicable(ICollection) |
Determines if this selection state is appropriate for use with the specified selection. |
| IsCommandToBeFilteredOut(CommandID) |
True if the specified command should not be enabled for this selection state. The method is evaluated for the coerced selection. (Inherited from SelectionState) |
| IsCommandToBeFilteredOutForMultipleSelection(CommandID) |
True if the specified command should not be enabled for this selection state. The method is evaluated for the coerced selection. (Inherited from SelectionState) |
| IsCommandToBeFilteredOutForSingleSelection(CommandID) |
