Detailed Description
This class wraps mostly often used operations with directories in files system. Its generally purposed to take care over the error code returned by system calls and throw SystemException in case of problems.

Member Function Documentation
void Directory::ensureExists |
( |
const std::string & |
path | ) |
[static] |
This method checks if the directory is exist and in case it isn't it will be created. The method throws SystemException if there are problems to check the directory or create it.
bool Directory::ensureExistsAndEmpty |
( |
const std::string & |
name, |
|
|
bool |
needEraseContent = 0 |
|
) |
| [static] |
- Returns:
- Non-zero if directory is empty, with eraseContent set to 1 always returns non-zero
This method creates the iterator prepared for enumeration of all files and directories inside of the directory given by path. If the directory is inaccessible for reading the SystemException will be thrown.
- Parameters:
-
[in] | path | The name of the directory to enumerate files in |
- Returns:
- The auto_ptr<> to the prepared iterator
DEEPSOLVER_BEGIN_NAMESPACE bool Directory::isExist |
( |
const std::string & |
path | ) |
[static] |
This method checks if the file system has the required entry and it is a directory by calling stat() system call. It never throes SystemException. This method returns zero even in case the directory is actually present but it existence cannot be checked due to wrong permissions.
- Returns:
- Non-zero if the directory is present and zero otherwise
