## Detailed Description

A new uri query object.

See create() for more details.

## Member Function Documentation

## ◆ create()

static Glib::RefPtr<Gst::QueryUri> Gst::QueryUri::create | ( |  | ) |
| static

Constructs a new query URI query object.

Use gst_query_unref() when done with it. An URI query is used to query the current URI that is used by the source or sink.

Returns
  a new Gst::Query.

## ◆ parse()

Glib::ustring Gst::QueryUri::parse | ( |  | ) | const

Parse an URI query, writing the URI into uri as a newly allocated string, if the respective parameters are non-NULL.

Free the string with g_free() after usage.

Returns
  the storage for the current URI.

## ◆ parse_uri_redirection()

Glib::ustring Gst::QueryUri::parse_uri_redirection | ( |  | ) | const

Parse an URI query, return URI, if the respective parameters.

Returns
  the storage for the redirect URI (may be empty).

## ◆ set()

void Gst::QueryUri::set | ( | const Glib::ustring & | uri | ) |

Answer a URI query by setting the requested URI.

Parameters

  uri | the URI to set.

## ◆ set_uri_redirection()

void Gst::QueryUri::set_uri_redirection | ( | const Glib::ustring & | uri | ) |

Answer a URI query by setting the requested URI redirection.

Parameters

  uri | the URI to set.
