public class WorkSource
extends Object
implements Parcelable
java.lang.Object | |
↳ | android.os.WorkSource |
Describes the source of some work that may be done by someone else. Currently the public representation of what a work source is is not defined; this is an opaque container.

WorkSource (WorkSource orig)
Create a new WorkSource that is a copy of an existing one. If orig is null, an empty WorkSource is created.
Parameters | |
---|---|
orig |
WorkSource
|
boolean add (WorkSource other)
Merge the contents of other WorkSource in to this one.
Parameters | |
---|---|
other |
WorkSource : The other WorkSource whose contents are to be merged. |
Returns | |
---|---|
boolean |
Returns true if any new sources were added. |
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 diff (WorkSource other)
Compare this WorkSource with another.
Parameters | |
---|---|
other |
WorkSource : The WorkSource to compare against. |
Returns | |
---|---|
boolean |
If there is a difference, true is returned. |
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:
x
, x.equals(x)
should return true
. x
and y
, x.equals(y)
should return true
if and only if y.equals(x)
returns true
. x
, y
, and z
, if x.equals(y)
returns true
and y.equals(z)
returns true
, then x.equals(z)
should return true
. x
and y
, multiple invocations of x.equals(y)
consistently return true
or consistently return false
, provided no information used in equals
comparisons on the objects is modified. x
, x.equals(null)
should return false
. The equals
method for class Object
implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x
and y
, this method returns true
if and only if x
and y
refer to the same object (x == y
has the value true
).
Note that it is generally necessary to override the hashCode
method whenever this method is overridden, so as to maintain the general contract for the hashCode
method, which states that equal objects must have equal hash codes.
Parameters | |
---|---|
o |
Object : the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if this object is the same as the obj argument; false otherwise. |
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:
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. |
boolean remove (WorkSource other)
Parameters | |
---|---|
other |
WorkSource
|
Returns | |
---|---|
boolean |
void set (WorkSource other)
Replace the current contents of this work source with the given work source. If other is null, the current work source will be made empty.
Parameters | |
---|---|
other |
WorkSource

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 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 . |
