reactjs - anti-pattern: updating (unrelated) state in a render() method -


i overriding recharts' tooltip functionality provide hover data elsewhere on page (in component).

<tooltip content={ this.showtooltipdata.bind(this) } />

showtooltipdata fires off action creator modifies part of state tree current render method not sensitive to, still dreaded anti-pattern warning:

warning: setstate(...): cannot update during existing state transition (such within `render` or component's constructor). render methods should pure function of props , state; constructor side-effects anti-pattern, can moved `componentwillmount`.

this warning both correct , incorrect, rendering component not affected state change. reason care warning can spam console (there 10s of 1000s of points hover over).

is there better way this? have considered using the target hover data component's "private" state (as opposed redux state in use) need data elsewhere well. moving functionality componentwillmount() impossible.

anyone found safer way override tooltip function?

freakin' crickets. once time i'll take on redux...

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
