## Detailed Description

Represents a protocol for use with wxURL.

Note that you may want to change the default time-out for HTTP/FTP connections and network operations (using SetDefaultTimeout()) since the default time-out value is quite long (60 seconds).

## Member Function Documentation

virtual bool wxProtocol::Abort | ( |  | ) |

pure virtual

Abort the current stream.

Warning
  It is advised to destroy the input stream instead of aborting the stream this way.

Returns
  Returns true, if successful, else false.

Implemented in wxFTP.

wxProtocolLog* wxProtocol::DetachLog | ( |  | ) |

Detach the existing logger without deleting it.

The caller is responsible for deleting the returned pointer if it's non-`NULL`.

virtual wxString wxProtocol::GetContentType | ( |  | ) | const

virtual

Returns the type of the content of the last opened stream.

It is a mime-type. May be an empty string if the content-type is unknown.

virtual wxProtocolError wxProtocol::GetError | ( |  | ) | const

virtual

Returns the last occurred error.

See also
  wxProtocolError

virtual wxInputStream* wxProtocol::GetInputStream | ( | const wxString & | path | ) |

pure virtual

Creates a new input stream on the specified path.

You can use all but seek() functionality of wxStream. Seek() isn't available on all streams. For example, HTTP or FTP streams don't deal with it. Other functions like StreamSize() and Tell() aren't available for the moment for this sort of stream. You will be notified when the EOF is reached by an error.

Returns
  Returns the initialized stream. You will have to delete it yourself once you don't use it anymore. The destructor closes the network connection.

See also
  wxInputStream

Implemented in wxFTP, and wxHTTP.

wxProtocolLog* wxProtocol::GetLog | ( |  | ) | const

inline

Return the current logger, may be NULL.

void wxProtocol::LogRequest | ( | const wxString & | str | ) |

Call wxProtocolLog::LogRequest() if we have a valid logger or do nothing otherwise.

void wxProtocol::LogResponse | ( | const wxString & | str | ) |

Call wxProtocolLog::LogResponse() if we have a valid logger or do nothing otherwise.

bool wxProtocol::Reconnect | ( |  | ) |

Tries to reestablish a previous opened connection (close and renegotiate connection).

Returns
  true, if the connection is established, else false.

void wxProtocol::SetDefaultTimeout | ( | wxUint32 | Value | ) |

Sets a new default timeout for the network operations.

The default timeout is 60 seconds.

See also
  wxSocketBase::SetTimeout

void wxProtocol::SetLog | ( | wxProtocolLog * | log | ) |

Set the logger, deleting the old one and taking ownership of this one.

Parameters

  log | New logger allocated on the heap or NULL.

virtual void wxProtocol::SetPassword | ( | const wxString & | user | ) |

virtual

Sets the authentication password.

Reimplemented in wxFTP.

virtual void wxProtocol::SetUser | ( | const wxString & | user | ) |

virtual

Sets the authentication user.

Reimplemented in wxFTP.
