Hello, I have a question.
It is a simple Server example TclOO implementaiton below. I mark with yellow two lines, where I can use mymethod command to set private methods of class as callbacks. Both of this callbacks execute in class instance context. Is it possible do same thing with nx? I want incapsulate server logic inside nx::Class and set private method as callback to accept connection and reading data.
#!/usr/bin/env tclsh
package require oo::util ;# for 'mymethod' command package require logger
logger::initNamespace proj::Server debug
oo::class create proj::mock::Server {
constructor { port } { my variable projVersion_ my variable port_ my variable socket_
set projVersion_ "0.1" set port_ $port
::logger::tree::proj::Server::debug "Init mock Server $projVersion_"
# it works! set socket_ [socket -server [mymethod Accept_clb] $port] } ;# constructor
method Accept_clb { sock addr port } { my variable clients_
::logger::tree::proj::Server::debug "Accepting connection with $addr $port" set clients_(addr,$sock) [list $addr $port]
fconfigure $sock -translation binary -buffering none fileevent $sock readable [mymethod Echo_clb $sock] ;# it works too! ::logger::tree::proj::Server::debug "Setting callback private method" } ;# Accept_clb
method Echo_clb { sock } { my variable clients_
::logger::tree::proj::Server::debug "Readable callback call"
if { [eof $sock] } { ::logger::tree::proj::Server::debug "No more data in socket"
close $sock unset clients_(addr,$sock) } else { set binary_msg [read $sock 2] binary scan $binary_msg "H*" string_msg
::logger::tree::proj::Server::debug "Readed 2 bytes"
if [string length $string_msg] { ::logger::tree::proj::Server::debug "Sending 2 bytes left"
puts -nonewline $sock $binary_msg } } } ;# Echo_clb
destructor { my variable socket_ close $socket_
::logger::tree::proj::Server::debug "Destroing Server" } ;# destructor
} ;# dms::mock::server
set s [proj::mock::Server new 1950]
vwait forever
