Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

From interface android.os.Parcelable

Fields

public static final Creator<MidiDeviceStatus> CREATOR

Added in API level 23

Public Methods

public int describeContents ()

Added in API level 23

Describe the kinds of special objects contained in this Parcelable's marshalled representation.

Returns

a bitmask indicating the set of special object types marshalled by the Parcelable.

public MidiDeviceInfo getDeviceInfo ()

Added in API level 23

Returns the MidiDeviceInfo of the device.

Returns

the device info

public int getOutputPortOpenCount (int portNumber)

Added in API level 23

Returns the number of clients currently connected to the specified output port. Unlike input ports, an output port can be opened by multiple clients at the same time.

Parameters

portNumber	the output port's port number

Returns

output port open count

public boolean isInputPortOpen (int portNumber)

Added in API level 23

Returns true if an input port is open. An input port can only be opened by one client at a time.

Parameters

portNumber	the input port's port number

Returns

input port open status

public String toString ()

Added in API level 23

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

   getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Returns

a printable representation of this object.

public void writeToParcel (Parcel parcel, int flags)

Added in API level 23

Flatten this object in to a Parcel.

Parameters

parcel	The Parcel in which the object should be written.
flags	Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`.
