Member Function Documentation

void openvrml::stream_listener::stream_available ( const std::string &  uri,
const std::string &  media_type 
)

Called once the stream is available for use.

This function calls do_stream_available.

Parameters:
[in]urithe URI associated with the stream.
[in]media_typethe MIME media type for the stream.
void openvrml::stream_listener::data_available ( const std::vector< unsigned char > &  data)

Called when data is available.

This function calls do_data_available.

Parameters:
[in]datathe data.
void openvrml::stream_listener::do_stream_available ( const std::string &  uri,
const std::string &  media_type 
) [private, pure virtual]

Called by stream_available.

Concrete stream_listeners must override this function.

Parameters:
[in]urithe URI associated with the stream.
[in]media_typethe MIME media type for the stream.
void openvrml::stream_listener::do_data_available ( const std::vector< unsigned char > &  data) [private, pure virtual]

Called by data_available.

Parameters:
[in]datathe data.
