java - Analyzing memory with MAT - question about UTF characters -

-

i .hprof file , i'm analyzing eclipse memory analyser (mat).

i run top component report and, in duplicate strings section, mat detects string instances identical content.

i'm working string.intern() , other homework me, not question. report shows me duplicated strings these:

  • \u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000....
  • \u000a\u0009\u0009
  • \u000a\u0009\u0009\u0009\u0009 , on.

other strings readable, but, how these ones? i'm thinking xml parsing (i use jibx in app).

my questions are:

  • what think these strings coming? how can analyse them better?
  • if xml parsing or else, how can clean/clear them after parsing? maybe jibx 1.0.1 release old these issues?

any suggestion these utf-8 like strings appreciated. in advance.

you can right-click on suspicious string , select list objects/with incoming references. show objects reference strings.

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.
