int describeContents ()
Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel, int)
, the return value of this method must include the CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. |
MidiDeviceInfo getDeviceInfo ()
Returns the MidiDeviceInfo
of the device.
Returns | |
---|---|
MidiDeviceInfo |
the device info |
int getOutputPortOpenCount (int portNumber)
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 |
int : the output port's port number |
Returns | |
---|---|
int |
output port open count |
boolean isInputPortOpen (int portNumber)
Returns true if an input port is open. An input port can only be opened by one client at a time.
Parameters | |
---|---|
portNumber |
int : the input port's port number |
Returns | |
---|---|
boolean |
input port open status |
String toString ()
Returns a string representation of the object. In general, the toString
method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
The toString
method for class Object
returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@
', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
Returns | |
---|---|
String |
a string representation of the object. |
void writeToParcel (Parcel parcel, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
parcel |
Parcel : The Parcel in which the object should be written. |
flags |
int : Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE . |
