Detailed Description

An interface to simplify asynchronously reading a resource_istream.

Constructor & Destructor Documentation

openvrml::stream_listener::~stream_listener ( ) throw ()

pure virtual

Destroy.

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]	uri	the URI associated with the stream.
[in]	media_type	the 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] data the data.

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

privatepure virtual

Concrete stream_listeners must override this function.

Parameters

[in]	uri	the URI associated with the stream.
[in]	media_type	the MIME media type for the stream.
