assert_select_encoded(element = nil, &block) Instance Public methods Extracts the content of an element, treats it as encoded HTML and runs nested assertion on it. You typically call this method within another assertion to operate on all currently selected elements. You can also pass an element or array of elements. The content of each element is un-encoded, and wrapped in the root element encoded. It then calls the block with all un-encoded elements. # Selects all bold tags fr

WIN32OLE_PARAM#ole_type Instance Public methods Returns OLE type of WIN32OLE_PARAM object(parameter of OLE method). tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook') method = WIN32OLE_METHOD.new(tobj, 'SaveAs') param1 = method.params[0] puts param1.ole_type # => VARIANT

cipher.auth_tag([ tag_len ] â string Instance Public methods Gets the authentication tag generated by Authenticated Encryption Cipher modes (GCM for example). This tag may be stored along with the ciphertext, then set on the decryption cipher to authenticate the contents of the ciphertext against changes. If the optional integer parameter tag_len is given, the returned tag will be tag_len bytes long. If the parameter is omitted, the maximum length of 16 bytes will be returned. For

search_field(object_name, method, options = {}) Instance Public methods Returns an input of type âsearchâ for accessing a specified attribute (identified by method) on an object assigned to the template (identified by object_name). Inputs of type âsearchâ may be styled differently by some browsers. search_field(:user, :name) # => <input id="user_name" name="user[name]" type="search" /> search_field(:user, :name, autosave: false) # => <input autosave="false" id="user_
