Class IndexOutput
Abstract base class for output to a file in a Directory. A random-access output stream. Used for all Lucene index output operations.
IndexOutput may only be used from one thread, because it is not thread safe (it keeps internal state like file position).Implements

Syntax
public abstract class IndexOutput : DataOutput, IDisposableProperties
Checksum
Returns the current checksum of bytes written so far
Declaration
public abstract long Checksum { get; }Property Value
| Type | Description |
|---|---|
| long |
See Also
Length
Gets or Sets the file length. By default, this property's setter does nothing (it's optional for a Directory to implement it). But, certain Directory implementations (for example FSDirectory) can use this to inform the underlying IO system to pre-allocate the file to the specified size. If the length is longer than the current file length, the bytes added to the file are undefined. Otherwise the file is truncated.
Declaration
public virtual long Length { get; set; }Property Value
| Type | Description |
|---|---|
| long |

Position
Returns the current position in this file, where the next write will occur.
