4.4.2.5. getSupportedEditExtensions

The getSupportedEditExtensions method has to return a list of all file extensions (in lower case) for which the content handler shall be available as editor application. In our example, the content handler shall just be used for viewing but not for editing. Therefore, the getSupportedEditExtensions method has to return an empty array:
    public String[] getSupportedEditExtensions()
    {
        return new String[0];
    }
Given this implementation, the edit functionality is not available for any node.
