public ParcelUuid (UUID uuid)
Constructor creates a ParcelUuid instance from the

.

UUID : UUID |
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 object)
Compares this ParcelUuid to another object for equality. If object
is not null
, is a ParcelUuid instance, and all bits are equal, then
true
is returned.
Parameters | |
---|---|
object |
Object : the Object to compare to.
This value may be null . |
Returns | |
---|---|
boolean |
true if this ParcelUuid is equal to object
or false if not. |
fromString
public static ParcelUuid fromString (String uuid)
Creates a new ParcelUuid from a string representation of UUID
.
Parameters | |
---|---|
uuid |
String : the UUID string to parse. |
Returns | |
---|---|
ParcelUuid |
a ParcelUuid instance. |
Throws | |
---|---|
NullPointerException |
if uuid is null . |
IllegalArgumentException |
if uuid is not formatted correctly. |
getUuid
public UUID getUuid ()
Get the UUID
represented by the ParcelUuid.
Returns | |
---|---|
UUID |
UUID contained in the ParcelUuid. |
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 ParcelUuid For example: 0000110B-0000-1000-8000-00805F9B34FB will be the return value.
Returns | |
---|---|
String |
a String instance. |
writeToParcel
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
dest |
Parcel : The Parcel in which the object should be written.
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 |
