Makes the Freezable object unmodifiable or tests whether it can be made unmodifiable.
protected:
virtual bool FreezeCore(bool isChecking);
protected virtual bool FreezeCore (bool isChecking);
abstract member FreezeCore : bool -> bool
override this.FreezeCore : bool -> bool
Protected Overridable Function FreezeCore (isChecking As Boolean) As Boolean
Parameters
- isChecking
- Boolean
true
to return an indication of whether the object can be frozen (without actually freezing it); false
to actually freeze the object.
Returns
If isChecking
is true
, this method returns true
if the 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.
Remarks
Do not call this method directly (except when calling base in an implementation). This method is called internally by the CanFreeze property (with isChecking
equal to true
) and the Freeze method (with isChecking
equal to false
).
Notes to Inheritors
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(Freezable, Boolean) 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 specifying true
for isChecking
).
