Initializes the new instance of the IntervalAppointmentCollection class.

Determines whether an element is in the ReadOnlyCollection<(Of <(<'T>)>)>.

Copies the entire ReadOnlyCollection<(Of <(<'T>)>)> to a compatible one-dimensional Array, starting at the specified index of the target array.

Returns an enumerator that iterates through the ReadOnlyCollection<(Of <(<'T>)>)>.

Searches for the specified object and returns the zero-based index of the first occurrence within the entire ReadOnlyCollection<(Of <(<'T>)>)>.

Refreshes the HasItems property value.

Raises the PropertyChanged event using the provided arguments.

Gets the number of elements contained in the ReadOnlyCollection<(Of <(<'T>)>)> instance.

Gets the Boolean value specifying whether collection has items.

Gets the element at the specified index.

Returns the IList<(Of <(<'T>)>)> that the ReadOnlyCollection<(Of <(<'T>)>)> wraps.

Occurs when an item is added or removed.

Occurs when a property value changes.

Adds an item to the IList. This implementation always throws NotSupportedException.

Removes all items from the IList. This implementation always throws NotSupportedException.

Occurs when the collection changes.

Determines whether the IList contains a specific value.

Copies the elements of the ICollection to an Array, starting at a particular Array index.

Returns an enumerator that iterates through a collection.

Determines the index of a specific item in the IList.

Inserts an item to the IList at the specified index. This implementation always throws NotSupportedException.

Gets a value indicating whether the IList has a fixed size.

Gets a value indicating whether the IList is read-only.

Gets a value indicating whether access to the ICollection is synchronized (thread safe).

Gets or sets the element at the specified index.

Occurs when a property value changes.

Removes the first occurrence of a specific object from the IList. This implementation always throws NotSupportedException.

Removes the IList item at the specified index. This implementation always throws NotSupportedException.

Gets an object that can be used to synchronize access to the ICollection.
