Public Member Functions | |
Creators | |
| DataBuf ()=default | |
| Default constructor. | |
| DataBuf (size_t size) | |
| Constructor with an initial buffer size. | |
| DataBuf (const byte *pData, size_t size) | |
| Constructor, copies an existing buffer. | |
Manipulators | |
| using | iterator = std::vector< byte >::iterator |
| using | const_iterator = std::vector< byte >::const_iterator |
| void | alloc (size_t size) |
| Allocate a data buffer of at least the given size. Note that if the requested size is less than the current buffer size, no new memory is allocated and the buffer size doesn't change. | |
| void | resize (size_t size) |
| Resize the buffer. Existing data is preserved (like std::realloc()). | |
| void | reset () |
| Reset value. | |
| iterator | begin () noexcept |
| const_iterator | cbegin () const noexcept |
| iterator | end () noexcept |
| const_iterator | cend () const noexcept |
| size_t | size () const |
| uint8_t | read_uint8 (size_t offset) const |
| void | write_uint8 (size_t offset, uint8_t x) |
| uint16_t | read_uint16 (size_t offset, ByteOrder byteOrder) const |
| void | write_uint16 (size_t offset, uint16_t x, ByteOrder byteOrder) |
| uint32_t | read_uint32 (size_t offset, ByteOrder byteOrder) const |
| void | write_uint32 (size_t offset, uint32_t x, ByteOrder byteOrder) |
| uint64_t | read_uint64 (size_t offset, ByteOrder byteOrder) const |
| void | write_uint64 (size_t offset, uint64_t x, ByteOrder byteOrder) |
| int | cmpBytes (size_t offset, const void *buf, size_t bufsize) const |
| Equivalent to: memcmp(&pData_[offset], buf, bufsize) | |
| byte * | data (size_t offset=0) |
| Returns a data pointer. | |
| const byte * | c_data (size_t offset=0) const |
| Returns a (read-only) data pointer. | |
| const char * | c_str (size_t offset=0) const |
| Returns a (read-only) C-style string pointer. | |
| bool | empty () const |
