Class FileHandle

Defined in File file_handle.hpp

Class Documentation

class FileHandle

File handle class to encapsulate a file descriptor, allowing RAII closing of the file descriptor.

Public Functions

FileHandle() = default

inline explicit FileHandle(int fd, const std::string &path) noexcept

FileHandle(FileHandle &&rhs) = default

FileHandle(const FileHandle &other) = delete

FileHandle &operator=(FileHandle &&rhs) = default

FileHandle &operator=(const FileHandle &other) = delete

inline explicit operator bool() const noexcept

inline bool operator!() const noexcept

inline bool valid() const noexcept

Checks for valid file descriptor value.

Returns:: boolean if valid file descriptor

inline int native() const noexcept

Retusn the file descriptor value used in this file handle operation.

Returns:: file descriptor value

inline bool close() noexcept

Closes file descriptor and resets it to initial value.

Returns:: boolean if file descriptor was successfully closed

inline ~FileHandle(): Destructor implicitly closes the internal file descriptor.

Private Members

int fd_ = {init_value}: file descriptor

std::string path_ = {}: chunk file path

Private Static Attributes

static constexpr const int init_value = {-1}: initial file descriptor
