OracleLob overview

Public Fields

public fieldstatic (Shared in Visual Basic)Null Represents a null OracleLob object.

Public Properties

public propertyCanRead Overridden. Gets a value indicating whether the LOB stream can be read.
public propertyCanSeek Overridden. Gets a value indicating whether forward and backward seek operations can be performed.
public propertyCanWrite Overridden. Always returns true, regardless of whether the LOB supports writing or not.
public propertyChunkSize Gets a value indicating the minimum number of bytes to retrieve from or send to the server during a read/write operation.
public propertyConnection Gets the OracleConnection used by this instance of the OracleLob.
public propertyIsBatched Gets a value indicating whether an application called the BeginBatch method.
public propertyIsNull Gets a value that indicates whether the OracleLob is a Null stream.
public propertyIsTemporary Gets a value indicating whether the OracleLob is a temporary LOB.
public propertyLength Overridden. Gets a value that returns the size of the OracleLob.
public propertyLobType Gets a value that returns the LOB data type.
public propertyPosition Overridden. Gets the current read position in the OracleLob stream.
public propertyValue Gets the common language runtime stream value equivalent of the underlying value.

Public Methods

public methodAppend Appends data from the specified LOB to the current LOB.
public methodBeginBatch Overloaded. Prevents server-side triggers from firing while performing multiple write operations.
public methodBeginRead (inherited from Stream) Begins an asynchronous read operation.
public methodBeginWrite (inherited from Stream) Begins an asynchronous write operation.
public methodClone Creates a new OracleLob object that references the same Oracle LOB as the original OracleLob object.
public methodClose Overridden. Closes the OracleLob.
public methodCopyTo Overloaded. Copies from this OracleLob to a destination OracleLob.
public methodCreateObjRef (inherited from MarshalByRefObject) Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.
public methodDispose Releases the unmanaged resources used by the OracleLob and optionally releases the managed resources.
public methodEndBatch Allows server-side triggers to resume firing after performing multiple write operations.
public methodEndRead (inherited from Stream) Waits for the pending asynchronous read to complete.
public methodEndWrite (inherited from Stream) Ends an asynchronous write operation.
public methodEquals (inherited from Object) Overloaded. Determines whether two Object instances are equal.
public methodErase Overloaded. Erases data from this OracleLob.
public methodFlush Overridden. Not currently supported.
public methodGetHashCode (inherited from Object) Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table.
public methodGetLifetimeService (inherited from MarshalByRefObject) Retrieves the current lifetime service object that controls the lifetime policy for this instance.
public methodGetType (inherited from Object) Gets the Type of the current instance.
public methodInitializeLifetimeService (inherited from MarshalByRefObject) Obtains a lifetime service object to control the lifetime policy for this instance.
public methodRead 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 methodReadByte (inherited from Stream) 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.
public methodSeek Overridden. Sets the position on the current OracleLob stream.
public methodSetLength Overridden. Sets the length of the OracleLob stream to a value less than the current length.
public methodToString (inherited from Object) Returns a String that represents the current Object.
public methodWrite 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.
public methodWriteByte (inherited from Stream) Writes a byte to the current position in the stream and advances the position within the stream by one byte.

Protected Methods

protected methodCreateWaitHandle (inherited from Stream) Allocates a WaitHandle object.
protected methodFinalize (inherited from Object) Overridden. Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

In C# and C++, finalizers are expressed using destructor syntax.

protected methodMemberwiseClone (inherited from Object) Creates a shallow copy of the current Object.
