* the left or right). So, we may want to optimize that by avoiding actual array modification until information about

|

* <pre>
|

* <ol>
|

* <li>
|
||||
* Client of this class enters <code>'defer changes'</code> mode (calls this method with <code>'true'</code> argument).

* That means that all subsequent changes will not actually modify backed array data and will be stored separately;
|
||||
* </li>
|
||||
* <li>
|

* Number of target changes are applied to the current object via standard API
|

* ({@link #insert(com.intellij.openapi.editor.impl.DocumentImpl, CharSequence, int) insert},

* {@link #remove(com.intellij.openapi.editor.impl.DocumentImpl, int, int, CharSequence) remove} and

|
||||
* </li>
|
||||
* <li>
|
||||
* Client of this class indicates that <code>'massive change time'</code> is over by calling this method with <code>'false'</code>
|
||||
* argument. That flushes all deferred changes (if any) to the backed data array and makes every subsequent change to
|

* be immediate flushed to the backed array;
