equals(Object object)
Compares this ParcelUuid to another object for equality. |

ParcelUuid (UUID uuid)
Constructor creates a ParcelUuid instance from the
given UUID.
| Parameters | |
|---|---|
uuid |
UUID:
UUID
|
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. |
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. |
| Returns | |
|---|---|
boolean |
true if this ParcelUuid is equal to object
or false if not.
|
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.
|
UUID getUuid ()
Get the UUID represented by the ParcelUuid.
| Returns | |
|---|---|
UUID |
UUID contained in the ParcelUuid. |
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:
Developers
hashCode method
must consistently return the same integer, provided no information
used in equals 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.
equals(Object)
method, then calling the hashCode method on each of
the two objects must produce the same integer result.
equals(java.lang.Object)
method, then calling the hashCode 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.
As much as is reasonably practical, the hashCode method defined by
class Object does return distinct integers for distinct
objects. (This is typically implemented by converting the internal
address of the object into an integer, but this implementation
technique is not required by the
JavaTM programming language.)
| Returns | |
|---|---|
int |
a hash code value for this object. |
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. |
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. |
flags |
int:
Additional flags about how the object should be written.
May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
