WorkSource

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.

Summary

Inherited constants

From interface android.os.Parcelable

Fields

public static final Creator<WorkSource> CREATOR

Public constructors

WorkSource()

Create an empty work source.

WorkSource(WorkSource orig)

Create a new WorkSource that is a copy of an existing one.

Public methods

boolean add(WorkSource other)

Merge the contents of other WorkSource in to this one.

void clear()

Clear this WorkSource to be empty.

int describeContents()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

boolean diff(WorkSource other)

Compare this WorkSource with another.

boolean equals(Object o)

Indicates whether some other object is "equal to" this one.

int hashCode()

Returns a hash code value for the object.

boolean remove(WorkSource other)
void set(WorkSource other)

Replace the current contents of this work source with the given work source.

String toString()

Returns a string representation of the object.

void writeToParcel(Parcel dest, int flags)

Flatten this object in to a Parcel.

Public constructors

WorkSource

Added in API level 9
WorkSource ()

Create an empty work source.

WorkSource

Added in API level 9
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

Public methods

add

Added in API level 9
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.

clear

Added in API level 9
void clear ()

Clear this WorkSource to be empty.

describeContents

Added in API level 9
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.

diff

Added in API level 9
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.

equals

Added in API level 9
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 return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values 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.
  • For any non-null reference value 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.

hashCode

Added in API level 9
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 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.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode 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(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.

remove

Added in API level 9
boolean remove (WorkSource other)

Parameters
other WorkSource
Returns
boolean

set

Added in API level 9
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

toString

Added in API level 9
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.

writeToParcel

Added in API level 9
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.

Hooray!
