java - REGEX matching problem -

-

my entering string can in format tim0.vw0 ( starts tim or cnt or enc followed numbers, point , @ end char or chars digit @ end). how find out if entering string matches regex ?

something do:

import java.util.arrays;  public class test {     public static void main(string[] args) {          string regexp = "(tim|cnt|enc)\\d+\\.\\p{alpha}+\\d";          (string test : arrays.aslist("tim0.vw0",  "tim0.vw5", "tim0.0",                                          "tim99.a5",  "cnt0vw0",  "abc0.vw0",                                          "-tim0.vw0", "tim9.8x",  "enc0.55"))             system.out.printf("%-10s: %s%n", test, test.matches(regexp));     } }

output:

tim0.vw0  : true tim0.vw5  : true tim0.0    : false tim99.a5  : true cnt0vw0   : false abc0.vw0  : false -tim0.vw0 : false tim9.8x   : false enc0.55   : false

Javascript line number mapping -

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
