ObservableUndoableTextChangeStack Class

public class ObservableUndoableTextChangeStack : DisposableObject, IDisposable, IUndoableTextChangeStack

public ObservableUndoableTextChangeStack(IUndoableTextChangeStack stack)

Parameter	Type	Description
stack	IUndoableTextChangeStack	The IUndoableTextChangeStack to wrap.

public int Capacity { get; set; }

Property Value

int:

The capacity of the stack.

Remarks

If a new text change added to the stack causes the stack to exceed its capacity, the text changes at the bottom of the stack are removed until the stack no longer exceeds its capacity.

public int Count { get; }

Property Value

int:

The count of text changes on the stack.

public bool IsAtSavePoint { get; }

Property Value

bool:

true if the last text change on the stack is a save point; otherwise, false.

public bool Contains(IUndoableTextChange textChange)

Parameter	Type	Description
textChange	IUndoableTextChange	The IUndoableTextChange to look for in the list.

Returns

bool:

true if the collection contains the specified IUndoableTextChange; otherwise, false.

public void CopyTo(IUndoableTextChange[] array, int arrayIndex)

Parameter	Type	Description
array	IUndoableTextChange[]	The one-dimensional IUndoableTextChange array that is the destination of the elements copied from the collection. The array must have zero-based indexing.
arrayIndex	int	The zero-based index in array at which copying begins.

protected override void Dispose(bool disposing)

Parameter	Type	Description
disposing	bool	true to release both managed and unmanaged resources; false to release only unmanaged resources.

Remarks

This method is called by the public Dispose method and the Finalize method. Dispose invokes this method with the disposing parameter set to true. Finalize invokes this method with disposing set to false.

public IEnumerator<IUndoableTextChange> GetEnumerator()

Returns

IEnumerator<IUndoableTextChange>:

An IEnumerator object for the entire collection

Remarks

Enumerators are intended to be used only to read data in the collection. Enumerators cannot be used to modify the underlying collection.

The enumerator does not have exclusive access to the collection.

When an enumerator is instantiated, it takes a snapshot of the current state of the collection. If changes are made to the collection, such as adding, modifying or deleting elements, the snapshot gets out of sync and the enumerator throws an InvalidOperationException. Two enumerators instantiated from the same collection at the same time can have different snapshots of the collection.

public IUndoableTextChange GetTextChange(int index)

Parameter	Type	Description
index	int	The index of the text change to check.

Returns

IUndoableTextChange:

The IUndoableTextChange that the specified location in the stack.

public int IndexOf(IUndoableTextChange textChange)

Parameter	Type	Description
textChange	IUndoableTextChange	The IUndoableTextChange to look for in the list.

Returns

int:

The index of the IUndoableTextChange in the list, or -1 if not found.
