Class FileChannelImpl
- AutoCloseable, ByteChannel, Channel, Closeable, GatheringByteChannel, InterruptibleChannel, ReadableByteChannel, ScatteringByteChannel, WritableByteChannel
This file is not user visible !
But alas, Java does not have a concept of friendly packages
so this class is public.
Instances of this class are created by invoking getChannel
Upon a Input/Output/RandomAccessFile object.

toString
public String toString()
Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into
System.out.println()
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a
RuntimeException.
This method will be called when performing string
concatenation with this object. If the result is
null, string concatenation will instead
use
"null".
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode()).
- toString in interface Object
- the String representing this Object, which may be null
