void BASE_IMPEXP | mrpt::system::deleteFiles (const std::string &s) |

bool BASE_IMPEXP | mrpt::system::fileExists (const std::string &fileName) |
Test if a given file (or directory) exists. More... | |
bool BASE_IMPEXP | mrpt::system::directoryExists (const std::string &fileName) |
Test if a given directory exists (it fails if the given path refers to an existing file). More... | |
std::string BASE_IMPEXP | mrpt::system::fileNameStripInvalidChars (const std::string &filename) |
Replace invalid filename chars by underscores ('_'). More... | |
std::string BASE_IMPEXP | mrpt::system::fileNameChangeExtension (const std::string &filename, const std::string &newExtension) |

uint64_t BASE_IMPEXP | mrpt::system::getFileSize (const std::string &fileName) |

time_t BASE_IMPEXP | mrpt::system::getFileModificationTime (const std::string &filename) |
Return the time of the file last modification, or "0" if the file doesn't exist. More... | |
std::string BASE_IMPEXP | mrpt::system::filePathSeparatorsToNative (const std::string &filePath) |
Windows: replace all '/'->'\' , in Linux/MacOS: replace all '\'->'/'. More... | |
bool BASE_IMPEXP | mrpt::system::copyFile (const std::string &sourceFile, const std::string &targetFile, std::string *outErrStr=NULL, bool copyAttribs=true) |
Copies file sourceFile to targetFile. More... | |
bool BASE_IMPEXP mrpt::system::copyFile | ( | const std::string & | sourceFile, |
const std::string & | targetFile, | ||
std::string * | outErrStr = NULL , |
||
bool | copyAttribs = true |
||
) |
Copies file sourceFile to targetFile.
If the target file exists, it will be overwritten. If the target file cannot be overwritten, the function first tries to change its permissions/attributes and retries opening it for write.
bool BASE_IMPEXP mrpt::system::createDirectory | ( | const std::string & | dirName | ) |
Creates a directory.
bool BASE_IMPEXP mrpt::system::deleteFile | ( | const std::string & | fileName | ) |
Deletes a single file.
For multiple files see deleteFiles
void BASE_IMPEXP mrpt::system::deleteFiles | ( | const std::string & | s | ) |
Delete one or more files, especified by the (optional) path and the file name (including '?' or '*') - Use forward slash ('/') for directories for compatibility between Windows and Linux, since they will be internally traslated into backward slashes ('\') if MRPT is compiled under Windows.
bool BASE_IMPEXP mrpt::system::deleteFilesInDirectory | ( | const std::string & | s, |
bool | deleteDirectoryAsWell = false |
||
) |
Delete all the files in a given directory (nothing done if directory does not exists, or path is a file).
bool BASE_IMPEXP mrpt::system::directoryExists | ( | const std::string & | fileName | ) |
Test if a given directory exists (it fails if the given path refers to an existing file).
std::string BASE_IMPEXP mrpt::system::extractFileDirectory | ( | const std::string & | filePath | ) |
Extract the whole path (the directory) of a filename from a complete path plus name plus extension.
This function works for either "/" or "\" directory separators.
std::string BASE_IMPEXP mrpt::system::extractFileExtension | ( | const std::string & | filePath, |
bool | ignore_gz = false |
||
) |
Extract the extension of a filename.
For example, for "dummy.cpp", it will return "cpp". If "ignore_gz" is true, the second extension will be returned if the file name ends in ".gz", for example, for "foo.map.gz", this will return "map".
std::string BASE_IMPEXP mrpt::system::extractFileName | ( | const std::string & | filePath | ) |
Extract just the name (without extension) of a filename from a complete path plus name plus extension.
This function works for either "/" or "\" directory separators.
bool BASE_IMPEXP mrpt::system::fileExists | ( | const std::string & | fileName | ) |
Test if a given file (or directory) exists.
std::string BASE_IMPEXP mrpt::system::fileNameChangeExtension | ( | const std::string & | filename, |
const std::string & | newExtension | ||
) |
Replace the filename extension by another one.
Example:
std::string BASE_IMPEXP mrpt::system::fileNameStripInvalidChars | ( | const std::string & | filename | ) |
Replace invalid filename chars by underscores ('_').
Invalid chars are identified by those not being alphanumeric or: ".-#%$&()+[]{}"
std::string BASE_IMPEXP mrpt::system::filePathSeparatorsToNative | ( | const std::string & | filePath | ) |
Windows: replace all '/'->'\' , in Linux/MacOS: replace all '\'->'/'.
std::string BASE_IMPEXP mrpt::system::getcwd | ( | ) |
Returns the current working directory.
time_t BASE_IMPEXP mrpt::system::getFileModificationTime | ( | const std::string & | filename | ) |
Return the time of the file last modification, or "0" if the file doesn't exist.
uint64_t BASE_IMPEXP mrpt::system::getFileSize | ( | const std::string & | fileName | ) |
Return the size of the given file, or size_t(-1) if some error is found accessing that file.
std::string BASE_IMPEXP mrpt::system::getTempFileName | ( | ) |
Returns the name of a proposed temporary file name.
bool BASE_IMPEXP mrpt::system::renameFile | ( | const std::string & | oldFileName, |
const std::string & | newFileName, | ||
std::string * | error_msg = NULL |
||
) |
Renames a file - If the target path is different and the filesystem allows it, it will be moved to the new location.
