Remarks
Instances of this class represent an ISO/IEC 7816-4 channel opened to a Secure Element. It can be either a logical channel or the basic channel. They can be used to send APDUs to the secure element. Channels are opened by calling the Session.openBasicChannel(byte[]) or Session.openLogicalChannel(byte[]) methods.

Methods
| Name | Description |
|---|---|
| Clone() |
Creates and returns a copy of this object. (Inherited from Object) |
| Close() |
Closes this channel to the Secure Element. |
| Construct(JniObjectReference, JniObjectReferenceOptions) |
Delegates construction of this peer to the runtime's value manager. (Inherited from JavaObject) |
| Dispose() |
Releases the resources held by this Java peer. (Inherited from Object) |
| Dispose(Boolean) |
Releases the resources held by this Java peer. (Inherited from Object) |
| DisposeUnlessReferenced() |
Asks the value manager to dispose this peer unless its mapping retains this same managed instance. (Inherited from JavaObject) |
| Equals(Object) |
Tests whether another managed peer refers to the same Java object. (Inherited from JavaObject) |
| Equals(Object) |
Indicates whether some other object is "equal to" this one. (Inherited from Object) |
| GetHashCode() |
Returns a hash code value for the object. (Inherited from Object) |
| GetSelectResponse() |
Returns the data as received from the application select command inclusively the status word received at applet selection. |
| JavaFinalize() |
Obsolete.
Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object) |
| Notify() |
Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object) |
| NotifyAll() |
Wakes up all threads that are waiting on this object's monitor. (Inherited from Object) |
| SelectNext() |
Performs a selection of the next Applet on this channel that matches to the partial AID specified in the openBasicChannel(byte[] aid) or openLogicalChannel(byte[] aid) method. |
| SetHandle(IntPtr, JniHandleOwnership) |
Sets the Handle property. (Inherited from Object) |
| SetPeerReference(JniObjectReference, JniObjectReferenceOptions) |
Stores a reference value in the control block without creating a JNI reference copy. (Inherited from JavaObject) |

| ToString() |
Returns a string representation of the object. (Inherited from Object) |
| Transmit(Byte[]) |
Transmit an APDU command (as per ISO/IEC 7816-4) to the Secure Element. |
| UnregisterFromRuntime() |
Unregisters this Java peer from the interop runtime. (Inherited from Object) |
| Wait() |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object) |
| Wait(Int64, Int32) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
| Wait(Int64) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
