Class Channel

Definition

Namespace:

Tizen.Core

Assembly:

Tizen.Core.dll

The class for managing communication channels between tasks of Tizen Core.

public class Channel : IDisposable

Inheritance

object

Channel

Implements

System.IDisposable

Remarks

Channels are essential in inter-task communications because they provide a reliable way to exchange messages and data. By creating a channel, you can establish a connection between two tasks that need to communicate with each other. Once created, both tasks can send and receive messages through the channel. It's important to note that channels have a limited capacity, so make sure to handle message overflows appropriately. Additionally, remember to close the channel once it's no longer needed to avoid resource leaks.

Constructors

Channel()

Creates a new channel with a sender and a receiver.

Declaration

public Channel()

Remarks

This constructor initializes a new channel that enables communication between a sender and a receiver. It throws exceptions if any errors occur during initialization due to insufficient memory or invalid operations.

Examples

In the following code snippet, we attempt to initialize a new channel by calling the constructor. However, if there is not enough memory available, an OutOfMemoryException is thrown. We handle this exception by displaying a message in the console.

try
{
   var channel = new Channel();
}
catch (OutOfMemoryException)
{
   Console.WriteLine("Exception occurs");
}

Exceptions

Type	Condition
System.OutOfMemoryException	Thrown when out of memory.
System.InvalidOperationException	Thrown when failed because of an invalid operation.

Properties

Receiver

Gets the channel receiver instance.

Declaration

public ChannelReceiver Receiver { get; }

Property Value

Type	Description
ChannelReceiver

Remarks

This property provides access to the channel receiver instance that handles incoming messages from other applications. By utilizing this instance, you can subscribe to specific channels and receive notifications accordingly. It is crucial to understand the concept of channels in order to effectively utilize this feature. For more details on channels, refer to the official documentation.

Sender

Gets the channel sender instance.

Declaration

public ChannelSender Sender { get; }

Property Value

Type	Description
ChannelSender

Remarks

This property provides access to the channel sender instance that can be used to send messages through the specified channel. It ensures that only one sender instance per channel exists in order to avoid any conflicts during message transmission.

Methods

Dispose()

Release any unmanaged resources used by this object.

Declaration

public void Dispose()

Remarks

Channels are essential in inter-task communications because they provide a reliable way to exchange messages and data. By creating a channel, you can establish a connection between two tasks that need to communicate with each other. Once created, both tasks can send and receive messages through the channel. It's important to note that channels have a limited capacity, so make sure to handle message overflows appropriately. Additionally, remember to close the channel once it's no longer needed to avoid resource leaks.

Dispose(bool)

Release any unmanaged resources used by this object.

Declaration

protected virtual void Dispose(bool disposing)

Parameters

Type	Name	Description
bool	disposing	If true, disposes any disposable objects. If false, does not dispose disposable objects.

Remarks

Channels are essential in inter-task communications because they provide a reliable way to exchange messages and data. By creating a channel, you can establish a connection between two tasks that need to communicate with each other. Once created, both tasks can send and receive messages through the channel. It's important to note that channels have a limited capacity, so make sure to handle message overflows appropriately. Additionally, remember to close the channel once it's no longer needed to avoid resource leaks.

~Channel()

Finalizes an instance of the Channel class.

Declaration

protected ~Channel()
