| Position | Gets the current read position in the OracleLob stream. (Inherited from Devart.Data.Oracle.OracleLob) |
| ReadTimeout | Gets or sets a value, in miliseconds, that determines how long the stream will attempt to read before timing out. (Inherited from System.IO.Stream) |
| Value | Gets the value of the OracleLob object. (Inherited from Devart.Data.Oracle.OracleLob) |
| WriteTimeout | Gets or sets a value, in miliseconds, that determines how long the stream will attempt to write before timing out. (Inherited from System.IO.Stream) |
Public Methods
| Name | Description | |
|---|---|---|
 | Append | Overloaded. Appends the supplied data to the current OracleLob instance. (Inherited from Devart.Data.Oracle.OracleLob) |
| BeginBatch | Overloaded. Prevents server-side triggers from firing while performing multiple write operations. (Inherited from Devart.Data.Oracle.OracleLob) |
| BeginRead | Begins an asynchronous read operation. (Consider using System.IO.Stream.ReadAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream) |
| BeginWrite | Begins an asynchronous write operation. (Consider using System.IO.Stream.WriteAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream) |
| Clone | Overridden. Creates a copy of the current OracleBFile object associated with the same physical file as the original. |
| Close | Overridden. Closes the current stream and releases any resources associated with it. |
| CloseFile | Closes the physical file associated with the OracleBFile object opened before by OpenFile method. |
| CopyTo | Overloaded. Copies data from the OracleBFile to a destination OracleLob. |
| CopyToAsync | Overloaded. Asynchronously reads the bytes from the current stream and writes them to another stream. (Inherited from System.IO.Stream) |
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from System.MarshalByRefObject) |
| Dispose | Disposes the resources allocated by the OracleLob object. (Inherited from Devart.Data.Oracle.OracleLob) |
| EndBatch | Allows server-side triggers to resume firing after performing multiple write operations. (Inherited from Devart.Data.Oracle.OracleLob) |
| EndRead | Waits for the pending asynchronous read to complete. (Consider using System.IO.Stream.ReadAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream) |
| EndWrite | Ends an asynchronous write operation. (Consider using System.IO.Stream.WriteAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream) |
| Erase | Overloaded. Erases all data from the OracleLob. (Inherited from Devart.Data.Oracle.OracleLob) |
| Flush | Flush/write all buffers for the current OracleLob. (Inherited from Devart.Data.Oracle.OracleLob) |
| FlushAsync | Overloaded. Asynchronously clears all buffers for this stream and causes any buffered data to be written to the underlying device. (Inherited from System.IO.Stream) |
| GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from System.MarshalByRefObject) |
| InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from System.MarshalByRefObject) |
| IsEqual | Determines whether the specified OracleLob object is equal to the current OracleLob. (Inherited from Devart.Data.Oracle.OracleLob) |
| OpenFile | Opens the file with which an OracleBFile object is associated. |
| Read | Overloaded. Overridden. Reads a sequence of bytes from the current OracleBFile stream and advances the position within the stream by the number of bytes read. |
| ReadAsync | Overloaded. Asynchronously reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read. (Inherited from System.IO.Stream) |
| ReadByte | Reads a byte from the stream and advances the position within the stream by one byte, or returns -1 if at the end of the stream. (Inherited from System.IO.Stream) |
| Seek | Sets the position on the current OracleLob stream. (Inherited from Devart.Data.Oracle.OracleLob) |
| SetFileName | Binds the OracleBFile object to a different file in the operating system. |
| SetLength | Sets length for OracleLob value. (Inherited from Devart.Data.Oracle.OracleLob) |
| ToString | Converts the current OracleLob object to a System.String. (Inherited from Devart.Data.Oracle.OracleLob) |
| Write | Overloaded. Writes a sequence of bytes to the current OracleLob stream, and advances the current position within this stream by the number of bytes written. (Inherited from Devart.Data.Oracle.OracleLob) |
| WriteAsync | Overloaded. Asynchronously writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written. (Inherited from System.IO.Stream) |
| WriteByte | Writes a byte to the current position in the Lob and advances the position within the stream by one byte. (Inherited from Devart.Data.Oracle.OracleLob) |
