bool

IsFDValid

Reads bytes with Seek(long, SeekOrigin) followed by Read(byte[], int, int).

Declaration

Property Value
Type Description
bool

Length

The number of bytes in the file.

Declaration
public override sealed long Length { get; }
Property Value
Type Description
long
Overrides

Methods

Clone()

Returns a clone of this stream.

Clones of a stream access the same data, and are positioned at the same point as the stream they were cloned from.

Expert: Subclasses must ensure that clones may be positioned at different points in the input from each other and from the stream they were cloned from.

Warning: Lucene never closes cloned IndexInputs, it will only do this on the original one. The original instance must take care that cloned instances throw ObjectDisposedException when the original one is closed.
Declaration
public override object Clone()
Returns
Type Description
object
Overrides

Dispose(bool)

Closes the stream to further operations.

Declaration
protected override void Dispose(bool disposing)
Parameters
Type Name Description
bool disposing
Overrides

ReadInternal(byte[], int, int)

IndexInput methods

Declaration
protected override void ReadInternal(byte[] b, int offset, int len)
Parameters
Type Name Description
byte[] b
int offset
int len
Overrides

SeekInternal(long)

Expert: implements seek. Sets current position in this file, where the next ReadInternal(byte[], int, int) will occur.

Declaration
protected override void SeekInternal(long position)
Parameters
Type Name Description
long position
Overrides
