Class LoopingByteInputStream

java.lang.Object
  java.io.InputStream
      java.io.ByteArrayInputStream
          com.brackeen.javagamebook.util.LoopingByteInputStream

All Implemented Interfaces:

java.io.Closeable

public class LoopingByteInputStream
extends java.io.ByteArrayInputStream

The LoopingByteInputStream is a ByteArrayInputStream that loops indefinitly. The looping stops when the close() method is called.

Possible ideas to extend this class:

• Add an option to only loop a certain number of times.

Constructor Detail

LoopingByteInputStream

public LoopingByteInputStream(byte[] buffer)

Creates a new LoopingByteInputStream with the specified byte array. The array is not copied.

Method Detail

read

public int read(byte[] buffer,
                int offset,
                int length)

Reads length bytes from the array. If the end of the array is reached, the reading starts over from the beginning of the array. Returns -1 if the array has been closed.

Overrides:

read in class java.io.ByteArrayInputStream

close

public void close()
           throws java.io.IOException

Closes the stream. Future calls to the read() methods will return 1.

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.ByteArrayInputStream

Throws:

java.io.IOException
