Assembly: WindowsBase (in windowsbase.dll)
true if the Freezable should simply return whether it can be frozen. false if the Freezable instance should actually freeze itself when this method is called.
Return ValueIf isChecking is true, this method returns true if this Freezable can be made unmodifiable, or false if it cannot be made unmodifiable. If isChecking is false, this method returns true if the if the specified Freezable is now unmodifiable, or false if it cannot be made unmodifiable, with the side effect of having begun to change the frozen status of this object.
Do not call this method directly (except when calling base in an implementation). This method is called internally by CanFreeze (with isChecking equal to true) and Freeze (with isChecking equal to false).Notes to Implementers: Freezable implementers must override this method when the class contains data that is not stored using dependency properties. A typical implementation would call base, then call the static Freeze method on all Freezable typed properties that the class contains, returning true only if all properties were frozen (or could have been frozen, in the case of passing through a false value for isChecking).
