Method Details

readByte

public byte readByte()
              throws IOException

Description copied from class: DataInput

Reads and returns a single byte.

Specified by:

readByte in class DataInput

Throws:

IOException

See Also:

• DataOutput.writeByte(byte)

readBytes

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

Description copied from class: DataInput

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

Specified by:

readBytes in class DataInput

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

See Also:

• DataOutput.writeBytes(byte[],int)

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Throws:

IOException

skipBytes

public void skipBytes(long numBytes)
               throws IOException

Description copied from class: DataInput

Skip over numBytes bytes. This method may skip bytes in whatever way is most optimal, and may not have the same behavior as reading the skipped bytes. In general, negative numBytes are not supported.

Specified by:
