virtual std::string TestPVChannel::getRemoteAddress ( )

inlinevirtual

Returns the channel's remote address, signal name, etc... For example:

client side channel would return server's address, e.g. "/192.168.1.101:5064"
server side channel would return underlying bus address, e.g. "#C0 S1".

The value returned here will changed depending on the connection status. A disconnected channel should return an empty() string.

Reimplemented from BaseChannel.

Definition at line 200 of file utilities.h.

200 { return "localhost:1234"; }
