Public Member Functions inherited from CBlobT< char > | |
| CBlobT () | |
| Default constructor - makes new Blob ready to accept any data. | |
| CBlobT (const OnTransfer &ot) | |
| Take ownership constructor. | |
| ~CBlobT () | |
| Destructor - ensures that allocated memory (if any) is freed. | |
| void | CheckIdx (size_t index) const |
| Check the validity of item index (only in debug mode) | |
| char * | Data () |
| Return pointer to the first data item - non-const version. | |
| const char * | Data () const |
| Return pointer to the first data item - const version. | |
| char * | Data (size_t index) |
| Return pointer to the index-th data item - non-const version. | |
| const char * | Data (size_t index) const |
| Return pointer to the index-th data item - const version. | |
| size_t | Size () const |
| Return number of items in the Blob. | |
| size_t | MaxSize () const |
| Return total number of items that can fit in the Blob without buffer reallocation. | |
| size_t | GetReserve () const |
| Return number of additional items that can fit in the Blob without buffer reallocation. | |
| char * | GrowSizeNC (size_t num_items) |
| Grow number of data items in Blob by given number - doesn't construct items. | |
| char * | MakeFreeSpace (size_t num_items) |
| Ensures that given number of items can be added to the end of Blob. | |
| OnTransfer | Transfer () |
Public Member Functions inherited from ByteBlob | |
| ByteBlob () | |
| default constructor - initializes empty blob | |
| ByteBlob (const ByteBlob &src) | |
| copy constructor | |
| ByteBlob (BlobHeader *const &src) | |
| move constructor - take ownership of blob data | |
| ~ByteBlob () | |
| destructor | |
| bool | IsEmpty () const |
| return true if blob doesn't contain valid data | |
| size_t | Length () const |
| return the number of valid data bytes in the blob | |

| byte * | Begin () |
| return pointer to the first byte of data - non-const version | |
| const byte * | Begin () const |
| return pointer to the first byte of data - const version | |
| void | Clear () |

| void | Free () |
| free the blob's memory | |
| void | AppendRaw (const void *p, size_t num_bytes) |
| append new bytes at the end of existing data bytes - reallocates if necessary | |
| void | AppendRaw (const ByteBlob &src) |
| append bytes from given source blob to the end of existing data bytes - reallocates if necessary | |
| byte * | Prepare (size_t num_bytes) |
| Reallocate if there is no free space for num_bytes bytes. | |
| byte * | Append (size_t num_bytes) |
| Increase Length() by num_bytes. | |
| void | SmartAlloc (size_t new_size) |
| reallocate blob data if needed | |
| void | FixTail () const |
| fixing the four bytes at the end of blob data - useful when blob is used to hold string | |
