public EditOperation(Parcel src,
 ClassLoader loader)

Method Details

writeToParcel

public void writeToParcel(@NonNull
 Parcel dest,
 int flags)

Description copied from interface: Parcelable

The subclass implements the method to flatten its contents by calling the methods of Parcel for its primitive values.

Parameters:

dest - the parcel to write the object's data to

flags - the flags about how the object should be written

commit

public void commit()

Description copied from class: UndoOperation

Called when this undo state is being committed to the undo stack. The implementation should perform the initial edits and save any state that may be needed to undo them.

Specified by:

commit in class UndoOperation<Editor>

undo

public void undo()

Description copied from class: UndoOperation

Called when this undo state is being popped off the undo stack (in to the temporary redo stack). The implementation should remove the original edits and thus restore the target object to its prior value.

Specified by:

undo in class UndoOperation<Editor>

redo

public void redo()

Description copied from class: UndoOperation

Called when this undo state is being pushed back from the transient redo stack to the main undo stack. The implementation should re-apply the edits that were previously removed by UndoOperation.undo().

Specified by:

redo in class UndoOperation<Editor>

forceMergeWith

public void forceMergeWith(Editor.EditOperation edit)

Forcibly creates a single merged edit operation by simulating the entire text contents being replaced.

toString

public String toString()

Overrides:

toString in class Object
