Constructor Detail

CorruptingIndexOutput

public CorruptingIndexOutput(Directory dir,
                             long byteToCorrupt,
                             IndexOutput out)

Method Detail

getName

public String getName()

Description copied from class: IndexOutput

Returns the name used to create this IndexOutput. This is especially useful when using Directory.createTempOutput(java.lang.String, java.lang.String, org.apache.lucene.store.IOContext).

Overrides:

getName in class IndexOutput

close

public void close()
           throws IOException

Description copied from class: IndexOutput

Closes this stream to further operations.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in class IndexOutput

Throws:

IOException

corruptFile

protected void corruptFile()
                    throws IOException

Throws:

IOException

getFilePointer

public long getFilePointer()

Description copied from class: IndexOutput

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

Specified by:

getFilePointer in class IndexOutput

getChecksum

public long getChecksum()
                 throws IOException

Description copied from class: IndexOutput

Returns the current checksum of bytes written so far

Specified by:

getChecksum in class IndexOutput

Throws:

IOException

toString

public String toString()

Overrides:

toString in class IndexOutput

writeByte

public void writeByte(byte b)
               throws IOException

Description copied from class: DataOutput

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.

Specified by:

writeByte in class DataOutput

Throws:

IOException

See Also:

DataInput.readByte()

writeBytes

public void writeBytes(byte[] b,
                       int offset,
                       int length)
                throws IOException

Description copied from class: DataOutput

Writes an array of bytes.

Specified by:

writeBytes in class DataOutput

Parameters:

b - the bytes to write

offset - the offset in the byte array

length - the number of bytes to write

Throws:

IOException

DataInput.readBytes(byte[],int,int)
