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

NewBuffer(byte[])

Reads bytes with the Read(Stream, ByteBuffer, long) extension method for Stream.

Declaration
protected override void NewBuffer(byte[] newBuffer)
Parameters
Type Name Description
byte[] newBuffer
Overrides

ReadInternal(byte[], int, int)

Expert: implements buffer refill. Reads bytes from the current position in the input.

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

the array to read bytes into
int offset

the offset in the array to start storing bytes
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 pos)
Parameters
Type Name Description
long pos
