    Public Methods
     NameDescription
    Public MethodOverloaded. Appends the supplied data to the current OracleLob instance.  
    Public MethodOverloaded. Prevents server-side triggers from firing while performing multiple write operations.  
    Public MethodBegins an asynchronous read operation. (Consider using System.IO.Stream.ReadAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream)
    Public MethodBegins an asynchronous write operation. (Consider using System.IO.Stream.WriteAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream)
    Public MethodCreates a copy of the current OracleLob object.  
    Public MethodOverridden. Closes the current stream and releases any resources associated with it.  
    Public MethodOverloaded. Copies data from this OracleLob to a destination OracleLob.  
    Public MethodOverloaded. Asynchronously reads the bytes from the current stream and writes them to another stream. (Inherited from System.IO.Stream)
    Public MethodCreates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from System.MarshalByRefObject)
    Public MethodDisposes the resources allocated by the OracleLob object.  
    Public MethodAllows server-side triggers to resume firing after performing multiple write operations.  
    Public MethodWaits 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)
    Public MethodEnds an asynchronous write operation. (Consider using System.IO.Stream.WriteAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream)
    Public MethodOverloaded. Erases data from the specified OracleLob.  
    Public MethodOverridden. Flush/write all buffers for the current OracleLob.  
    Public MethodOverloaded. Asynchronously clears all buffers for this stream and causes any buffered data to be written to the underlying device. (Inherited from System.IO.Stream)
    Public MethodRetrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from System.MarshalByRefObject)
    Public MethodObtains a lifetime service object to control the lifetime policy for this instance. (Inherited from System.MarshalByRefObject)
    Public MethodDetermines whether the specified OracleLob object is equal to the current OracleLob.  
    Public MethodOverloaded. Overridden. Reads a sequence of bytes from the current OracleLob stream and advances the position within the stream by the number of bytes read.  
    Public MethodOverloaded. 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)
    Public MethodReads 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)
    Public MethodOverridden. Sets the position on the current OracleLob stream.  
    Public MethodOverridden. Sets length for OracleLob value.  
    Public MethodConverts the current OracleLob object to a System.String.  
    Public MethodOverloaded. Overridden. Writes a sequence of bytes to the current OracleLob stream, and advances the current position within this stream by the number of bytes written.
