| Provides access to the underlying C GObject. | |
| const GdaBlobOp* | gobj () const |
| Provides access to the underlying C GObject. | |
| GdaBlobOp* | gobj_copy () |

| long | get_length () const |
| long | read (Blob& blob, long offset, long size) |
| Reads a chunk of bytes from the BLOB accessible through op into blob. | |
| long | write (Blob& blob, long offset) |
| Writes a chunk of bytes from a blob to the BLOB accessible through op. | |
| bool | read_all (Blob& blob) |
| Reads the whole contents of the blob manipulated by op into blob. | |
| bool | write_all (Blob& blob) |

| Glib::RefPtr< Gnome::Gda::BlobOp > | wrap (GdaBlobOp* object, bool take_copy=false) |
| A Glib::wrap() method for this object. | |
This object is a base class for individual database providers which support BLOB types. It supports operations to read and write data in a BLOB.

Writes a chunk of bytes from a blob to the BLOB accessible through op.
| blob | A Gda::Blob which contains the data to write. | |
| offset | Offset to write from the start of the blob (starts at 0). |
| bool Gnome::Gda::BlobOp::write_all | ( | Blob& | blob | ) |
Writes the whole contents of blob into the blob manipulated by op.
If necessary the resulting blob is truncated from its previous length.
