Class BufferedChecksumStreamInput

org.elasticsearch.common.io.stream.StreamInput

org.elasticsearch.common.io.stream.FilterStreamInput

org.elasticsearch.index.translog.BufferedChecksumStreamInput

All Implemented Interfaces:

,

public final class BufferedChecksumStreamInput
extends FilterStreamInput

Similar to Lucene's BufferedChecksumIndexInput, however this wraps a StreamInput so anything read will update the checksum

Method Details

getChecksum

public long getChecksum()

readByte

public byte readByte()
              throws 

Description copied from class: StreamInput

Reads and returns a single byte.

Overrides:

readByte in class FilterStreamInput

Throws:

readBytes

public void readBytes(byte[] b,
 int offset,
 int len)
               throws 

Description copied from class: StreamInput

Reads a specified number of bytes into an array at the specified offset.

Overrides:

readBytes in class FilterStreamInput

Parameters:

b - the array to read bytes into

offset - the offset in the array to start storing bytes

len - the number of bytes to read

Throws:

readShort

public short readShort()
                throws 

Overrides:

readShort in class FilterStreamInput

Throws:

readInt

public int readInt()
            throws 

Description copied from class: StreamInput

Reads four bytes and returns an int.

Overrides:

readInt in class FilterStreamInput

Throws:

readLong

public long readLong()
              throws 

Description copied from class: StreamInput

Reads eight bytes and returns a long.

Overrides:

readLong in class FilterStreamInput

Throws:

readVInt

public int readVInt()
             throws 

Description copied from class: StreamInput

Reads an int stored in variable-length format. Reads between one and five bytes. Smaller values take fewer bytes. Negative numbers will always use all 5 bytes and are therefore better serialized using StreamInput.readInt()

Overrides:

readVInt in class FilterStreamInput

Throws:

readVLong

public long readVLong()
               throws 

Description copied from class: StreamInput

Reads a long stored in variable-length format. Reads between one and ten bytes. Smaller values take fewer bytes. Negative numbers are encoded in ten bytes so prefer StreamInput.readLong() or StreamInput.readZLong() for negative numbers.

Overrides:

readVLong in class FilterStreamInput

Throws:

reset

public void reset()
           throws 

Overrides:

reset in class FilterStreamInput

Throws:

read

public int read()
         throws 

Overrides:

read in class FilterStreamInput

Throws:

markSupported

public boolean markSupported()

Overrides:

in class

skip

public long skip(long numBytes)
          throws 

Overrides:

in class

Throws:

mark

public void mark(int readlimit)

Overrides:

in class

resetDigest

public void resetDigest()

getSource

public  getSource()
