nonBlockingRead

public int nonBlockingRead(byte[] buff,
                           int start,
                           int count)

Description copied from class: StreamObject

This is the non-blocking read operation. It should never attempt to wait() or sleep() in a Coroutine. It should return as quickly as possible. This makes it safe to be called from within a native method. Note that this should NEVER be called with a count of zero.

The default StreamObject implementation of this uses the single byte read() method.

Specified by:

nonBlockingRead in interface BasicStream

Overrides:

nonBlockingRead in class StreamObject

Parameters:

buff - Destination byte array to hold incoming data.

start - Starting index in buff for incoming data.

count - Maximum number of bytes to read - should never be zero.

Returns:

greater than 0 = Number of bytes read.
0 = No bytes available to read at this time.
-1 = Stream end reached no further bytes to read.
-2 = IO Error.
Note that these values are different to the Stream.readBytes method.

closeStream

public boolean closeStream()
                    throws IOException

Description copied from interface: BasicStream

This is non-blocking. It returns true if the close completed, false if it did not, or throws an exception on error.

Specified by:

closeStream in interface BasicStream

Overrides:

closeStream in class StreamObject

Throws:

IOException

flushStream

public boolean flushStream()
                    throws IOException

Description copied from interface: BasicStream

This is non-blocking. It returns true if the flush completed, false if it did not, or throws an exception on error.

Throws:

IOException
