Method Detail

available

public int available()
              throws IOException

Overrides:

available in class InputStream

Returns:

finalize

protected void finalize()
                 throws IOException

Description copied from class: Object

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize method to dispose of system resources or to perform other cleanup.

Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored.

The finalize method in Object does nothing.

Overrides:

finalize in class Object

Throws:

IOException

getFD

public final FileDescriptor getFD()
                           throws IOException

public int read(byte[] abyte0)
         throws IOException

read

public int read(byte[] abyte0,
                int i,
                int j)
         throws IOException

Description copied from class: InputStream

Read byte data until there is no more available. This does not block for the balance of any data. If there is not data this returns -1. If there is some data but not all that is requested it returns what it has.
