问题 Using Resharper I get the following message: Ambiguous InvocationSolution ITicket.sln Project ITicket ITicket\frmMainTicket.cs:530 Ambiguous invocation: void DisableAllFields() (in class frmMainTicket) void DisableAllFields() (in class frmMainTicket) match I am new to coding and could use a little help. If I understand this correctly it is basically saying that I am calling a method and it is unsure what method I should use? I have never used Resharper before. Maybe I am confused on what

How to use jq for a query where key is a numeric string

由 一个人想着一个人 提交于 2019-12-11 06:08:18
问题 Recently discovered jq and am using it to format some data. How do I use it to access fields of a json object that happen to be numeric strings? For example, the following fails for me with an error: echo '{"20":"twenty"}' | jq .["20"] What's the right way to do this? 回答1: Immediate Answer: Use More Quotes In jq .["20"] , the double quotes are parsed as shell syntax, not jq syntax (shell quoting is character-by-character: One can switch quoting types within a larger string). Use single quotes

iOS: What is the processing overhead in invoking an Objective-C method?

问题 I am writing some real-time audio processing code, which is to be executed in an audio unit's render callback. This thread is at the highest priority level the system recognises. Apple instructs to minimise the amount of processing that goes on in this call. One of their recommendations is to avoid Objective-C method invocation. But why? What happens when an Objective-C method is invoked? what is the actual overhead? 回答1: Objective-C method resolution is dynamic. In other languages such as C

问题 I get the recursive construct overflow invocation error at the four public tuna parts (parts=maybe a class or something else?). It worked on the tutorial but not for me and can't seem to see where public class tuna { private int hour; private int minute; private int second; public tuna() { this(0,0,0); //default } public tuna(int h){ this(h,0,0); //with hours input } public tuna(int h, int m){ this(h,m,0); //with hours and minutes } public tuna(int h, int m, int s){ this(h,m,s); //with hours,

Juypter notebook currently has a limitation: Starting terminal in current directory How do I do this from command-line (no Anaconda or other GUI), without the following unacceptable hacky approaches? (and in particular where the notebook directory might well change between invocations, or between users?) Manually edit the hard path into your jupyter notebook config file, in the c.NotebookApp.notebook_dir parameter Embed hard paths into your notebook code. Must be absolute paths. (yukky). Also user-dependent. Can't distribute notebooks which handle files properly with paths relative to their

What is wrong with my Method.invoke call?

I just created the following minimalistic testcase: package testcase; public class Main { public static void main( String[] args ) throws Throwable { if ( args.length == 0 ) Main.class.getMethod( "main", String[].class ).invoke( null, new String[] { "test" } ); } } It should just run, with no output and no exception. The main method should be calling itself using reflection. However I get the following exception: Exception in thread "main" java.lang.IllegalArgumentException: argument type mismatch at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect
