问题 We are facing problem that camel file component readLockCheckInterval allow single file to be processed at a time and for next file camel lock, it will wait for readLockCheckInterval time. We have 10000 or more files which we want to process in parallel. I want to use maxMessagesPerPoll attribute for accessing multiple file per poll but with readLockCheckInterval because camel release the file lock if the file is still being copied. It will be great help if there will be any other way to

问题 I have this code and run it with Flawinder, and i get this output on the read() functions: "Check buffer boundaries if used in a loop including recursive loops" Can anyone see the problem? ** #include <stdlib.h> void func(int fd) { char *buf; size_t len; read(fd, &len, sizeof(len)); if (len > 1024) return; buf = malloc(len+1); read(fd, buf, len); buf[len] = '\0'; } ** 回答1: you should check the return value of read() to know whether call to read() was success or failure or if read() was

问题 InputStream is an Abstract class.Then how are we able to access System.in.And moreover int read() is an abstract method in InputStream class.Then how are we able to access System.in.read() method if read() is an abstract method. Like int a=System.in.read(); System.out.println((char)a); 回答1: I suggest you to read more about abstraction and inheritance methods in Java. If you extend an abstract class, you have to implement its abstract methods. This way, you provide an implementation for it,

问题 What is the best way to move directory with all its contents(files or folders) in C#? I used the following codes, but it throws The Directory is not empty exception : Microsoft.VisualBasic.FileIO.FileSystem.MoveDirectory(sourceFullName, destFullName, true); Directory.Move(sourceFullName, destFullName); //Added in edit 回答1: MSDN example enough for this. string sourceDirectory = @"C:\source"; string destinationDirectory = @"C:\destination"; try { Directory.Move(sourceDirectory,

问题 This question already has answers here : URL to load resources from the classpath in Java (14 answers) Closed 18 days ago . Just wanted to know which is the best way to read a file that may be in the classpath. The only thing i have is a property with the path of the file. For exemple: filepath=classpath:com/mycompany/myfile.txt filepath=file:/myfolder/myfile.txt Which is the best way to load an InputStream from that property? 回答1: You can use the URL method openStream, which returns an

问题 The title is pretty self-descriptive, but there's one part that caught my attention: newtype IO a = IO (State# RealWorld -> (# State# RealWorld, a #)) Stripping the newtype , we get: State# RealWorld -> (# State# RealWorld, a #) I don't know what State# stands for. Can we replace it with State like this: State RealWorld -> (State RealWorld, a) And can that be expressed as this, then? State (State RealWorld) a This particular construct caught my attention. I know that conceptually, type IO a =
