Public methods
describeContents
public 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(android.os.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.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
equals
public boolean equals (Object o)
Indicates whether some other object is "equal to" this one.
The equals
method implements an equivalence relation
on non-null object references:
- It is reflexive: for any non-null reference value
x
,x.equals(x)
should returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
Parameters | |
---|---|
o |
Object : This value may be null . |
Returns | |
---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getConnectionToSinkType
public int getConnectionToSinkType ()
Returns | |
---|---|
int |
How the current device is connected to the display sink. For example, the display
can be connected immediately to the device or there can be a receiver in between.
Value is CONNECTION_TO_SINK_UNKNOWN , CONNECTION_TO_SINK_BUILT_IN , CONNECTION_TO_SINK_DIRECT , or CONNECTION_TO_SINK_TRANSITIVE |
getManufactureWeek
public int getManufactureWeek ()
Returns | |
---|---|
int |
The week of manufacture which ranges from 1 to 53, or -1 it is not available. Typically, it is not present if model year is available. Value is between -1 and 53 inclusive |
getManufactureYear
public int getManufactureYear ()
Returns | |
---|---|
int |
The year of manufacture, or -1 it is not available. Typically, one of model year or manufacture year is available. Value is -1 or greater |
getManufacturerPnpId
public String getManufacturerPnpId ()
Returns the Manufacturer Plug and Play ID. This ID identifies the manufacture according to the list: https://uefi.org/PNP_ID_List. It consist of 3 characters, each character is an uppercase letter (A-Z).
Returns | |
---|---|
String |
Manufacturer Plug and Play ID.
This value cannot be null . |
getModelYear
public int getModelYear ()
Returns | |
---|---|
int |
Model year of the device. Return -1 if not available. Typically, one of model year or manufacture year is available. Value is -1 or greater |
getName
public String getName ()
Returns | |
---|---|
String |
Display name.
This value may be null . |
getProductId
public String getProductId ()
Returns | |
---|---|
String |
Manufacturer product ID.
This value cannot be null . |
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
HashMap
.
The general contract of hashCode
is:
- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCode
method must consistently return the same integer, provided no information used inequals
comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals
method, then calling thehashCode
method on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
equals
method, then calling thehashCode
method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns | |
---|---|
int |
a hash code value for this object. |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
writeToParcel
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
dest |
Parcel : This value cannot be null . |
flags |
int : Additional flags about how the object should be written.
May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE .
Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
