Remarks

This method tries to find the specified document in a list of already opened documents maintained by the DocumentManager. If the document is found, its instance is opened in the Spreadhseet. If the specified document has not been found in the opened documents, a delegate method specified by the contentAccessorByBytes parameter is called. It allows you to manually obtain a byte array from which to open a document (for instance, to load a document from a database).
