Class RadioOutputStream

java.lang.Object
  java.io.OutputStream
      com.sun.spot.peripheral.radio.RadioOutputStream

All Implemented Interfaces:

IRadioControl

Deprecated. Please use com.sun.spot.io.j2me.radiostream.RadioOutputStream

public class RadioOutputStream
extends OutputStream
implements IRadioControl

Helper class for "radiostream:" connections. This class provides an OutputStream to stream data to another Spot. You should NOT normally instantiate this class directly, but rather via the GCF framework: see the first reference below for more details.

Constructor Detail

RadioOutputStream

public RadioOutputStream(IRadiostreamProtocolManager dispatcher,
                         ConnectionID cid,
                         RadioPolicy initialPolicy,
                         IRadioPolicyManager radioPolicyManager)

Deprecated.

Parameters:

dispatcher - the PortBasedProtocolManager that will dispatch packets

cid - the ConnectionID object to be used

radioPolicyManager -

initialPolicy -

Method Detail

write

public void write(int arg0)
           throws NoAckException,
                  ChannelBusyException,
                  NoRouteException,
                  NoMeshLayerAckException

Deprecated.

Description copied from class: OutputStream

Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Subclasses of OutputStream must provide an implementation for this method.

Specified by:

write in class OutputStream

Parameters:

arg0 - the byte.

Throws:

NoAckException

ChannelBusyException

NoRouteException

NoMeshLayerAckException

flush

public void flush()
           throws NoAckException,
                  ChannelBusyException,
                  NoRouteException,
                  NoMeshLayerAckException

Deprecated.

Description copied from class: OutputStream

Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

The flush method of OutputStream does nothing.

Overrides:

flush in class OutputStream

Throws:

NoAckException

ChannelBusyException

NoRouteException

NoMeshLayerAckException

close

public void close()
           throws IOException

Deprecated.

Description copied from class: OutputStream

Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.

The close method of OutputStream does nothing.

Overrides:

close in class OutputStream

Throws:

IOException - if an I/O error occurs.

getFlushThreshold

public int getFlushThreshold()

Deprecated.

Get the flush threshold for this stream. Data written to the stream is only sent to the remote Spot when the flush threshold is reached, or when the current radio packet is full.

Returns:

number of bytes written to receiver before a radio packet is sent to the remote spot.

setFlushThreshold

public void setFlushThreshold(int ft)

Deprecated.

Set the flush threshold for this stream. Data written to the stream is only sent to the remote Spot when the flush threshold is reached. This method should only be called before writing any data to the stream.

Parameters:

ft - - number of bytes to write to receiver before a radio packet is sent to the remote spot - should be in the range 1 to (RadioPacket.getMaxMacPayloadSize() - IRadiostreamProtocolManager.DATA_OFFSET)

setRadioPolicy

public void setRadioPolicy(RadioPolicy selection)

Deprecated.

Description copied from interface: IRadioControl

Set the radio policy for this connection

Specified by:

setRadioPolicy in interface IRadioControl

Parameters:

selection - the policy required

getLocalPort

public byte getLocalPort()

Deprecated.

Description copied from interface: IRadioControl

Answer the port number for this connection

Specified by:

getLocalPort in interface IRadioControl

Returns:

the port number
