Provides access to the underlying C GObject. | |
const GstXML* | gobj () const |
Provides access to the underlying C GObject. | |

Fills the GstXML object with the corresponding elements from the XML file fname. | |
bool | parse_memory (const std::string& buffer, const std::string& root) |
Glib::RefPtr<Element> | get_element (const std::string& name) |
This function is used to get a pointer to the GstElement corresponding to name in the pipeline description. | |

Reimplemented from Gst::Object.
static Glib::RefPtr<XML> Gst::XML::create | ( | ) | [static] |
bool Gst::XML::parse_doc | ( | xmlDocPtr | doc, | |
const std::string & | root | |||
) |
Fills the GstXML object with the elements from the xmlDocPtr.
doc | A pointer to an xml document to parse. | |
root | The name of the root object to build. |
true
on success, false
otherwise. bool Gst::XML::parse_file | ( | const std::string & | filename, | |
const std::string & | root | |||
) |
Fills the GstXML object with the corresponding elements from the XML file fname.
Optionally it will only build the element from the element node root (if it is not 0
). This feature is useful if you only want to build a specific element from an XML file but not the pipeline it is embedded in.
Pass "-" as fname to read from stdin. You can also pass a URI of any format that libxml supports, including http.
fname | The filename with the xml description. | |
root | The name of the root object to build. |
true
on success, false
otherwise. bool Gst::XML::parse_memory | ( | const std::string & | buffer, | |
const std::string & | root | |||
) |
Glib::RefPtr<Element> Gst::XML::get_element | ( | const std::string & | name | ) |
This function is used to get a pointer to the GstElement corresponding to name in the pipeline description.
You would use this if you have to do anything to the element after loading.
name | The name of element to retrieve. |
Glib::RefPtr<const Element> Gst::XML::get_element | ( | const std::string & | name | ) | const |
This function is used to get a pointer to the GstElement corresponding to name in the pipeline description.
You would use this if you have to do anything to the element after loading.
name | The name of element to retrieve. |
Glib::ListHandle<Glib::RefPtr<Element>> Gst::XML::get_topelements | ( | ) |
Retrieve a list of toplevel elements.
Glib::ListHandle<Glib::RefPtr<const Element>> Gst::XML::get_topelements | ( | ) | const |
