readByte

public byte readByte()
              throws IOException

Description copied from class: StreamInput

Reads and returns a single byte.

Specified by:

readByte in class StreamInput

Throws:

IOException

readBytes

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

Description copied from class: StreamInput

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

Specified by:

readBytes in class StreamInput

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:

IOException

readBytesReference

public BytesReference readBytesReference()
                                  throws IOException

Description copied from class: StreamInput

Reads a bytes reference from this stream, might hold an actual reference to the underlying bytes of the stream.

Overrides:

readBytesReference in class StreamInput

Throws:

IOException

readBytesReference

public BytesReference readBytesReference(int length)
                                  throws IOException

Description copied from class: StreamInput

Reads a bytes reference from this stream, might hold an actual reference to the underlying bytes of the stream.

Overrides:

readBytesReference in class StreamInput

Throws:

IOException

reset

public void reset()
           throws IOException

Description copied from class: StreamInput

Resets the stream.

Specified by:

reset in class StreamInput

Throws:

IOException

close

public void close()
           throws IOException

Description copied from class: StreamInput

Closes the stream to further operations.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in class StreamInput

Throws:

IOException

read

public int read()
         throws IOException

Specified by:

read in class InputStream

Throws:

IOException

readFully

public void readFully(byte[] b)
               throws IOException

Overrides:

readFully in class StreamInput

Throws:

IOException

readShort

public short readShort()
                throws IOException

Overrides:

readShort in class StreamInput

Throws:

IOException

readInt

public int readInt()
            throws IOException

Description copied from class: StreamInput

Reads four bytes and returns an int.

Overrides:

readInt in class StreamInput

Throws:

IOException

readVInt

public int readVInt()
             throws IOException

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 StreamInput

Throws:

IOException

readVLong

public long readVLong()
               throws IOException

Description copied from class: StreamInput

Reads a long stored in variable-length format. Reads between one and nine bytes. Smaller values take fewer bytes. Negative numbers are not supported.

Overrides:

readVLong in class StreamInput
