Hubs are usually in a stack so that you can push a new hub into place that can intercept and handle events differently than the primary hub. .SH "SYNOPSIS" .IX Header "SYNOPSIS" .Vb 2 \& my $stack = Test2::API::Stack\->new; \& my $hub = $stack\->top; .Ve .SH "METHODS" .IX Header "METHODS" .ie n .IP "$stack = Test2::API::Stack\->\fInew()\fR" 4 .el .IP "\f(CW$stack\fR = Test2::API::Stack\->\fInew()\fR" 4 .IX Item "$stack = Test2::API::Stack->new()" This will create a new empty stack instance.

Optionally you can provide arguments that will be passed into the constructor for the Test2::Hub object. .Sp If you specify the \f(CW\*(C`\*(Aqclass\*(Aq => $class\*(C'\fR argument, the new hub will be an instance of the specified class. .Sp Unless your parameters specify \f(CW\*(Aqformatter\*(Aq\fR or \f(CW\*(Aqipc\*(Aq\fR arguments, the formatter and \s-1IPC\s0 instance will be inherited from the current top hub. You can set the parameters to \f(CW\*(C`undef\*(C'\fR to avoid having a formatter or \s-1IPC\s0 instance. .Sp If there is no top hub, and you do not ask to leave \s-1IPC\s0 and formatter undef, then a new formatter will be created, and the \s-1IPC\s0 instance from Test2::API will be used. .ie n .IP "$hub = $stack\->\fItop()\fR" 4 .el .IP "\f(CW$hub\fR = \f(CW$stack\fR\->\fItop()\fR" 4 .IX Item "$hub = $stack->top()" This will return the top hub from the stack.
