This interface is deprecated.
Use ChannelClient.Channel
.
A channel created through ChannelApi.openChannel(GoogleApiClient, String, String)
.
The implementation of this interface is parcelable and immutable, and implements
reasonable Object.equals(Object)
and Object.hashCode()
methods, so can be used in collections.

Inherited Method Summary
Public Methods
public abstract PendingResult < Status > addListener ( GoogleApiClient client, ChannelApi.ChannelListener listener)
Registers a listener to be notified of events for this channel. This is the same as ChannelApi.addListener(GoogleApiClient, ChannelApi.ChannelListener)
, but the
listener will only be notified of events for this channel. The listener will not
receive ChannelApi.ChannelListener.onChannelOpened(Channel)
events.
Calls to this method should balanced with removeListener(GoogleApiClient, ChannelApi.ChannelListener)
to avoid leaking
resources.
Listener events will be called on the main thread, or the handler specified on client
when it was built (using GoogleApiClient.Builder.setHandler(Handler)
).
Parameters
client | a connected client |
---|---|
listener | a listener which will be notified of changes to the specified stream |
public abstract PendingResult < Status > close ( GoogleApiClient client, int errorCode)
Closes this channel, passing an application-defined error code to the remote node.
The error code will be passed to ChannelApi.ChannelListener.onChannelClosed(Channel, int, int)
, and will
cause remote reads and writes to the channel to fail with ChannelIOException
.
The InputStream
and OutputStream
returned from getInputStream(GoogleApiClient)
or getOutputStream(GoogleApiClient)
should be closed prior to calling this
method. If they are not, both streams will throw ChannelIOException
on the next read or write operation.
errorCode == 0
is used to indicate that no error occurred.
Parameters
client | a connected client |
---|---|
errorCode | an app-defined error code to pass to the remote node |
public abstract PendingResult < Status > close ( GoogleApiClient client)
Closes this channel, making any future operations on it invalid.
This method behaves like close(GoogleApiClient, int)
, with errorCode == 0
.
Parameters
public abstract PendingResult < Channel.GetInputStreamResult > getInputStream ( GoogleApiClient client)
Opens the input side of the channel to receive data from the remote node. Methods on
the returned input stream may throw ChannelIOException
.
See GetInputStreamResult.getInputStream()
This method should only be used once on any channel, and once it was called, receiveFile(GoogleApiClient, Uri, boolean)
cannot be used.
Parameters
public abstract String getNodeId ()
Returns the node ID of the node on the other side of the channel.
public abstract PendingResult < Channel.GetOutputStreamResult > getOutputStream ( GoogleApiClient client)
Opens the output side of the channel to send data to the remote node. Methods on the
returned output stream may throw ChannelIOException
.
See GetOutputStreamResult.getOutputStream()
This method should only be used once on any channel, and once it was called, sendFile(GoogleApiClient, Uri, long, long)
cannot be used.
Parameters
public abstract String getPath ()
Returns the path that was used to open the channel.
public abstract PendingResult < Status > receiveFile ( GoogleApiClient client, Uri uri, boolean append)
Reads input from this channel into a file. This is equivalent to calling getInputStream(GoogleApiClient)
, reading from the input stream and writing
it to a file, but is implemented more efficiently. Writing to the file will be done in
a background process owned by Google Play Services.
This method should only be used once on any channel, and once it was called, getInputStream(GoogleApiClient)
cannot be used. The channel should not be
immediately closed after calling this method. To be notified when the file is ready,
install a ChannelApi.ChannelListener
,
with an implementation of ChannelApi.ChannelListener.onInputClosed(Channel, int, int)
.
Parameters
client | a connected client |
---|---|
uri | URI of the file into which data should be written. This should be a file
URI
for a file which is accessible to the current process for
writing. |
append | if true, data from the channel will be appended to the file, instead of overwriting it. |
public abstract PendingResult < Status > removeListener ( GoogleApiClient client, ChannelApi.ChannelListener listener)
Removes a listener which was previously added through addListener(GoogleApiClient, ChannelApi.ChannelListener)
.
Parameters
client | a connected client |
---|---|
listener | a listener which was added using addListener(GoogleApiClient, ChannelApi.ChannelListener)
|
public abstract PendingResult < Status > sendFile ( GoogleApiClient client, Uri uri)
Reads from a file into the output side of the channel. This is equivalent to calling getOutputStream(GoogleApiClient)
, reading from a file and writing into the OutputStream
,
but is implemented more efficiently. Reading from the file will be done in a background
process owned by Google Play Services.
This method should only be used once on any channel, and once it was called, getOutputStream(GoogleApiClient)
cannot be used. The channel should not be
immediately closed after calling this method. To be notified when the file has been
sent, install a ChannelApi.ChannelListener
,
with an implementation of ChannelApi.ChannelListener.onOutputClosed(Channel, int, int)
.
This method is identical to calling sendFile(GoogleApiClient, Uri, long, long)
with offset == 0
and length == -1
.
Parameters
client | a connected client |
---|---|
uri | URI of the file from which data should be read. This should be a file
URI
for a file which is accessible to the current process for
reading. |
public abstract PendingResult < Status > sendFile ( GoogleApiClient client, Uri uri, long startOffset, long length)
Reads from a file into the output side of the channel. This is equivalent to calling getOutputStream(GoogleApiClient)
, reading from a file and writing into the OutputStream
,
but is implemented more efficiently. Reading from the file will be done in a background
process owned by Google Play Services.
This method should only be used once on any channel, and once it was called, getOutputStream(GoogleApiClient)
cannot be used. The channel should not be
immediately closed after calling this method. To be notified when the file has been
sent, install a ChannelApi.ChannelListener
,
with an implementation of ChannelApi.ChannelListener.onOutputClosed(Channel, int, int)
.
Parameters
client | a connected client |
---|---|
uri | URI of the file from which data should be read. This should be a file
URI
for a file which is accessible to the current process for
reading. |
startOffset | byte offset from which to start reading |
length | maximum number of bytes to read from the file, or -1
if the file
should be read to its end. If the file doesn't contain enough bytes to reach length
, fewer bytes will be read. |
