public class MockIndexOutputWrapper
extends IndexOutput

Used by MockRAMDirectory 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.

Constructor Detail

MockIndexOutputWrapper

public MockIndexOutputWrapper(MockDirectoryWrapper dir,
                              IndexOutput delegate,
                              String name)

Construct an empty output buffer.

Method Detail

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

flush

public void flush()
           throws IOException

Description copied from class: IndexOutput

Forces any buffered output to be written.

Specified by:

flush in class IndexOutput

Throws:

IOException

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 len)
                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

len - the number of bytes to write

Throws:

IOException

See Also:

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

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

copyBytes

public void copyBytes(DataInput input,
                      long numBytes)
               throws IOException

Description copied from class: DataOutput

Copy numBytes bytes from input to ourself.

Overrides:

copyBytes in class DataOutput

Throws:

IOException

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 Object
