Iterating over a JSON array in scala -

-

i'm using json lib net.sf.json(http://json-lib.sourceforge.net/apidocs/net/sf/json/package-summary.html) in scala code. also, i'm using specs bdd framework (http://code.google.com/p/specs/) unit testing. in dobefore block, have following code:

dobefore {   iter = serversjson.iterator() }

serversjson jsonarray object. outside dobefore block, have declared variables used follows

var serversjson:jsonarray = null var iter:iterator[jsonarray] = null

but on compilation i'm getting following error.

error: type mismatch; found : java.util.iterator[?0] type ?0 required: java.util.iterator[net.sf.json.jsonarray] iter = serversjson.iterator()

i guess way have declared iter object outside dobefore incorrect. how fix this?

please thank you.

as indicated here, json library's iterator method returns raw iterator, not iterator[jsonarray]. you'll want declare follows:

var serversjson:jsonarray = null var iter:iterator[_] = null

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.
