Used by MockDirectoryWrapper to create an output stream that will throw an IOException on fake disk full, track max disk space actually used, and maybe throw random IOExceptions.

Constructors

MockIndexOutputWrapper(MockDirectoryWrapper, IndexOutput, string)

Construct an empty output buffer.

Declaration
public MockIndexOutputWrapper(MockDirectoryWrapper dir, IndexOutput @delegate, string name)
Parameters
Type Name Description
MockDirectoryWrapper dir
IndexOutput delegate
string name

Properties

Checksum

Returns the current checksum of bytes written so far

Declaration
public override long Checksum { get; }
Property Value
Type Description
long
Overrides
Lucene.Net.Store.IndexOutput.Checksum

Length

Gets or Sets the file length. By default, this property's setter does nothing (it's optional for a Lucene.Net.Store.Directory to implement it). But, certain Lucene.Net.Store.Directory implementations (for example Lucene.Net.Store.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 override long Length { get; set; }
Property Value
Type Description
long
Overrides
Lucene.Net.Store.IndexOutput.Length

Position

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

This was getFilePointer() in Lucene.
Declaration
public override long Position { get; }
Property Value
Type Description
long
Overrides
Lucene.Net.Store.IndexOutput.Position

Methods

CopyBytes(DataInput, long)

Copy numBytes bytes from input to ourself.

Declaration
public override void CopyBytes(DataInput input, long numBytes)
Parameters
Type Name Description
DataInput input
long numBytes
Overrides

Dispose(bool)

Closes this stream to further operations.

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

Flush()

Forces any buffered output to be written.

Declaration
public override void Flush()
Overrides
Lucene.Net.Store.IndexOutput.Flush()

Seek(long)

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

Declaration
[Obsolete("(4.1) this method will be removed in Lucene 5.0")]
public override void Seek(long pos)
Parameters
Type Name Description
long pos
Overrides
See Also
Position

ToString()

Returns a string that represents the current object.

Declaration
public override string ToString()
Returns
Type Description
string

A string that represents the current object.
Overrides

WriteByte(byte)

Writes a single byte.

The most primitive data type is an eight-bit byte. Files are accessed as sequences of bytes. All other data types are defined as sequences of bytes, so file formats are byte-order independent.
Declaration
public override void WriteByte(byte b)
Parameters
Type Name Description
byte b
Overrides
See Also
ReadByte()

WriteBytes(byte[], int, int)

Writes an array of bytes.

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

the bytes to write
int offset

the offset in the byte array
int len
