close

public void close()

Description copied from class: StreamInput

Closes the stream to further operations.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in class StreamInput

available

public int available()

Specified by:

ensureCanReadBytes

protected void ensureCanReadBytes(int length)
                           throws EOFException

Description copied from class: StreamInput

This method throws an EOFException if the given number of bytes can not be read from the this stream. This method might be a no-op depending on the underlying implementation if the information of the remaining bytes is not present.

Specified by:

ensureCanReadBytes in class StreamInput

Throws:

EOFException

readByte

public byte readByte()

Description copied from class: StreamInput

Reads and returns a single byte.

Specified by:

readByte in class StreamInput

readBytes

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

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
