bool dueca::websock::WebSocketsServerBase::isPrepared ( )

finalvirtual

indicate that everything is ready.

Implements dueca::Module.

		const DCOReader &	r ) const

pure virtual

Send data with, in a "tick"/"data" struct.

Implemented in dueca::websock::WebSocketsServer< Encoder, Decoder >.

◆ codeEmpty()

virtual void dueca::websock::WebSocketsServerBase::codeEmpty ( std::ostream & s ) const

pure virtual

Code empty, no data.

Implemented in dueca::websock::WebSocketsServer< Encoder, Decoder >.

Member Data Documentation

◆ readsingles

singleread_t dueca::websock::WebSocketsServerBase::readsingles

protected

Mapping connecting URL details to an object that reads a specific channel entry.

This is a map, indexed by Name+Entry, mapping URL basename + entry ID to SingleEntryRead objects with a read token. These are configured through the start script.

◆ autosingles

singleread_t dueca::websock::WebSocketsServerBase::autosingles

protected

Mapping connecting URL details to an object that reads a specific channel entry.

Same type as the readsingles, however, created automatically from channel entries detected in one of the monitor locations, and only created when a client asks for access.

◆ singlereadsmapped

singlereadmap_t dueca::websock::WebSocketsServerBase::singlereadsmapped

protected

Mapping connection id to SingleEntryRead objects.

A mapping from connection ID/pointer to the SingleEntryRead objects in use by these connections. These objects are either common with the readsingles or autosingles maps.

◆ followers

followread_t dueca::websock::WebSocketsServerBase::followers

protected

Mapping connecting URL details to an object that reads and follows the data in a specific channel entry.

Maps url name and entry id to a SingleEntryFollow object. The SingleEntryFollow object has a list of connections as clients that will get new data from the followed entry as it comes in.

◆ autofollowers

followread_t dueca::websock::WebSocketsServerBase::autofollowers

protected

Mapping connecting URL details to an object that reads and follows the data in a specific channel entry.

Maps url name and entry id to a SingleEntryFollow object, created on the basis of a monitor. The SingleEntryFollow object has a list of connections as clients that will get new data from the followed entry as it comes in.
