Examples of org.modeshape.jcr.api.Binary

org.modeshape.jcr.api.Binary
An extension of the standard {@link javax.jcr.Binary} interface, with methods to obtain the SHA-1 hash of the binary value.

                    // Try to get the MIME type for the binary value ...
                    org.modeshape.jcr.value.Property dataProp = node.getProperty(JcrLexicon.DATA, cache);
                    if (dataProp != null) {
                        Object dataValue = dataProp.getFirstValue();
                        if (dataValue instanceof Binary) {
                            Binary binaryValue = (Binary)dataValue;
                            // Get the name of this node's parent ...
                            String fileName = null;
                            NodeKey parentKey = node.getParentKey(cache);
                            if (parentKey != null) {
                                CachedNode parent = cache.getNode(parentKey);
                                Name parentName = parent.getName(cache);
                                fileName = stringFactory().create(parentName);
                            }
                            String mimeType = binaryValue.getMimeType(fileName);
                            if (mimeType != null) {
