The class to create, read, and write data from or into (virtual) files in memory.
| xl7::io::VirtualFile::VirtualFile | ( | void | ) |
Default constructor.
| xl7::io::VirtualFile::~VirtualFile | ( | void | ) |
Destructor.
| bool xl7::io::VirtualFile::Close | ( | ) | [virtual] |
Closes the file.
Implements xl7::io::IRom.
| OpenFlags xl7::io::VirtualFile::GetOpenFlags | ( | ) | const [inline, virtual] |
Returns the flags the file was opened with.
Implements xl7::io::IFile.
| unsigned xl7::io::VirtualFile::GetPointer | ( | ) | const [inline, virtual] |
Returns the current byte position to read or write data.
Implements xl7::io::IRom.
| unsigned xl7::io::VirtualFile::GetSize | ( | ) | const [virtual] |
Returns the size of the file, in bytes.
Implements xl7::io::IRom.
Initializes and opens the virtual file for reading or writing. Therefore, the data of the given file in the file system is read into the memory buffer (unless flags contains the write flag but not the append flag).
| bool xl7::io::VirtualFile::Init | ( | BufferedFile & | buffered_file | ) |
Initializes and opens the virtual file for reading. Therefore, the data of the given buffered file is read into the memory buffer.
| bool xl7::io::VirtualFile::Init | ( | BufferedFile & | buffered_file, | |
| const OpenFlags | flags | |||
| ) |
Initializes and opens the virtual file for reading or writing. Therefore, the data of the given buffered file is read into the memory buffer (unless flags contains the write flag but not the append flag).
| bool xl7::io::VirtualFile::Init | ( | void * | buffer, | |
| unsigned | bytes | |||
| ) |
Initializes and opens the virtual file for reading. Therefore, the data of the given buffer is read into the own memory buffer.
| bool xl7::io::VirtualFile::Init | ( | void * | buffer, | |
| unsigned | bytes, | |||
| const OpenFlags | flags | |||
| ) |
Initializes and opens the virtual file for reading or writing. Therefore, the data of the given buffer is read into the own memory buffer (unless flags contains the write flag but not the append flag).
| bool xl7::io::VirtualFile::Init | ( | File & | file | ) |
Initializes and opens the virtual file for reading. Therefore, the data of the given file in the file system is read into the memory buffer.
Initializes and opens the virtual file for reading. Therefore, the data of the given file in the file system is read into the memory buffer (unless flags contains the write flag but not the append flag).
| bool xl7::io::VirtualFile::IsOpen | ( | ) | const [inline, virtual] |
Checks whether the file is open.
Implements xl7::io::IRom.
| bool xl7::io::VirtualFile::Open | ( | const OpenFlags | flags | ) |
Opens the virtual file for reading or writing.
| bool xl7::io::VirtualFile::Open | ( | ) | [virtual] |
Opens the virtual file for reading.
Implements xl7::io::IRom.
| unsigned xl7::io::VirtualFile::Read | ( | void * | buffer, | |
| unsigned | bytes | |||
| ) | [virtual] |
Reads data from the file and returns the number of bytes read.
Implements xl7::io::IRom.
| unsigned xl7::io::VirtualFile::Seek | ( | signed | bytes, | |
| const SeekFlags | from = current | |||
| ) | [virtual] |
Resets the current byte position to read or write data by moving the pointer by the specified bytes. The function returns the new position.
Implements xl7::io::IRom.
| unsigned xl7::io::VirtualFile::SetPointer | ( | unsigned | pointer | ) | [virtual] |
Resets the current byte position to read or write data. The function returns the new position.
Resets the current position to read or write data. The function returns the new position.
Implements xl7::io::IRom.
| bool xl7::io::VirtualFile::SetSize | ( | unsigned | size | ) | [virtual] |
Sets the size of the file, in bytes. Truncates or appends the difference in bytes.
Implements xl7::io::IFile.
| unsigned xl7::io::VirtualFile::Write | ( | const void * | buffer, | |
| unsigned | bytes | |||
| ) | [virtual] |
Writes data to the file and returns the number of bytes written.
Implements xl7::io::IFile.
