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 associated with Pels that are not already included. 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 associated with Pels that are not already included. 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)	True if the specified command should not be enabled for this selection state. The method is evaluated for the coerced selection. (Inherited from SelectionState)
