openCMIS: get mime type of a document

From the content stream of a document, you can get the mime type of the document. ContentStream interface provides 'getMimeType' method, to get the mime type of a document.

String getMimeType()

Returns the MIME type of the stream or null if the MIME type is unknown

Example

                  ContentStream contentStream = document.getContentStream();

                 

                  if(contentStream == null){

                           System.out.println("There is no content stream associated with this document");

                           return;

                  }

                  String mimeType = contentStream.getMimeType();

                 

                  System.out.println("mimeType : " + mimeType);
