Poco::File

基于入门的环境及makefile。

#include<iostream>
#include<Poco/File.h>
 
using namespace std;
using namespace Poco;
int main(){
    File *myfile = new File("/home/ygy/work/poco/file/b.txt");
 
    myfile->createFile();
 
    cout<<"canRead():"<<myfile->canRead()<<endl;
    cout<<"canWrite():"<<myfile->canWrite()<<endl;
    myfile->copyTo("/home/ygy/work/poco/file/bin");
 
    cout<<"end"<<endl;
}

void copyTo(const std::string & path)const; 将该文件复制到某个目录，将文件内容复制到指定文件。

void createDirectories(); 　 创建所有的目录，即使目录的父目录不存在

bool createDirectory(); 　　在已存在的目录下创建目录。

　　Returns true if the directory has been created and false if it already exists

bool createFile(); 创建空文件

　　Returns true if the file has been created and false if the file already exists

Timestamp created() const;  这个返回类型还不知道怎么显示时间。

　　Returns the creation date of the file.

bool exists() const;

Timestamp getLastModified() const;  上次修改时间

FileSize getSize() const;　　返回文件字节数，目录是4096

bool isDevice() const;

　　Returns true if and only if the file is a device.

bool isDirectory() const;

　　Returns true if and only if the file is a directory.

bool isFile() const;

　　Returns true if and only if the file is a regular file.

bool isHidden() const;

bool isLink() const;

　　Returns true if and only if the file is a symbolic link

void moveTo( const std::string & path);

void list( std::vector < File > & files) const;    获得所有的File对象

void list( std::vector < std::string > & files) const;　　获得所有的name

#include<iostream>
#include<Poco/File.h>
 
using namespace std;
using namespace Poco;
int main(){
    File *myfile1 = new File("/home/ygy/work/poco/file");
    vector<string>files;
    vector<File>Files;
    myfile1->list(files);
    myfile1->list(Files);
    cout<<Files.size()<<endl;
    for(auto file:files ){
        cout<<file<<endl;
    }
}
