Inheritance diagram for Gnome::Gda::BlobOp:

| Public Member Functions | |
| long | get_length () const | 
| Opens an existing BLOB. | |
| const GdaBlobOp* | gobj () const | 
| Provides access to the underlying C GObject. | |
| GdaBlobOp* | gobj () | 
| Provides access to the underlying C GObject. | |
| GdaBlobOp* | gobj_copy () | 
| Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs. | |
| long | read (Blob& blob, long offset, long size) | 
| Reads a chunk of bytes from the BLOB into blob . | |
| bool | read_all (Blob& blob) | 
| Reads the whole contents of the blob manipulated by op into blob. | |
| long | write (Blob& blob, long offset) | 
| Writes a chunk of bytes from a blob to the BLOB accessible through op . | |
| bool | write_all (Blob& blob) | 
| Writes the whole contents of blob into the blob manipulated by op . | |

| 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.
| virtual Gnome::Gda::BlobOp::~BlobOp | ( | ) |  [virtual] | 
| Gnome::Gda::BlobOp::BlobOp | ( | ) |  [protected] | 
| static Glib::RefPtr<BlobOp> Gnome::Gda::BlobOp::create | ( | ) |  [static] | 
| long Gnome::Gda::BlobOp::get_length | ( | ) | const | 
Opens an existing BLOB.
The BLOB must be initialized by gda_connection_create_blob or obtained from a G::Value. FIXME: gda_connection_create_blob() no longer exists.
| const GdaBlobOp* Gnome::Gda::BlobOp::gobj | ( | ) | const  [inline] | 
| GdaBlobOp* Gnome::Gda::BlobOp::gobj | ( | ) |  [inline] | 
| GdaBlobOp* Gnome::Gda::BlobOp::gobj_copy | ( | ) | 
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
| long Gnome::Gda::BlobOp::read | ( | Blob& | blob, | |
| long | offset, | |||
| long | size | |||
| ) | 
Reads a chunk of bytes from the BLOB into blob .
| blob | A Gda::Blob to read data to. | |
| offset | Offset to read from the start of the blob (starts at 0). | |
| size | Maximum number of bytes to read. | 
| bool Gnome::Gda::BlobOp::read_all | ( | Blob& | blob | ) | 
Reads the whole contents of the blob manipulated by op into blob.
| blob | A Gda::Blob to read data to. | 
true if blob ->data contains the whole BLOB manipulated by op . | long Gnome::Gda::BlobOp::write | ( | Blob& | blob, | |
| long | offset | |||
| ) | 
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.
| blob | A Gda::Blob which contains the data to write. | 
true on success. 
| Glib::RefPtr<Gnome::Gda::BlobOp> wrap | ( | GdaBlobOp * | object, | |
| bool | take_copy = false | |||
| ) |  [related] | 
A Glib::wrap() method for this object.
| object | The C instance. | |
| take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
