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.
