asInputStream

public final SeekableInputStream asInputStream()

Returns an input view of this RandomAccessStream. Invoking this method several times, will return the same object.

Note that read access is NOT synchronized.

Returns:

a SeekableInputStream reading from this stream

asOutputStream

public final SeekableOutputStream asOutputStream()

Returns an output view of this RandomAccessStream. Invoking this method several times, will return the same object.

Note that write access is NOT synchronized.

Returns:

a SeekableOutputStream writing to this stream
