CREATOR

Added in API level 26
public static final Creator<VersionedPackage> CREATOR

Public constructors

VersionedPackage

Added in API level 26
public VersionedPackage (String packageName, 
                int versionCode)

Creates a new instance. Use PackageManager#VERSION_CODE_HIGHEST to refer to the highest version code of this package.

Parameters
packageName String: The package name. This value cannot be null.

versionCode int: The version code. Value is PackageManager.VERSION_CODE_HIGHEST or greater

VersionedPackage

Added in API level 28
public VersionedPackage (String packageName, 
                long versionCode)

Creates a new instance. Use PackageManager#VERSION_CODE_HIGHEST to refer to the highest version code of this package.

Parameters
packageName String: The package name. This value cannot be null.

versionCode long: The version code. Value is PackageManager.VERSION_CODE_HIGHEST or greater

Public methods

describeContents

Added in API level 26
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

Added in API level 26
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 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.

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.

getLongVersionCode

Added in API level 28
public long getLongVersionCode ()

Gets the version code.

Returns
long The version code. Value is PackageManager.VERSION_CODE_HIGHEST or greater

getPackageName

Added in API level 26
public String getPackageName ()

Gets the package name.

Returns
String The package name. This value cannot be null.

getVersionCode

Added in API level 26
Deprecated in API level 28
public int getVersionCode ()

This method was deprecated in API level 28.
use getLongVersionCode() instead.

Returns
int Value is PackageManager.VERSION_CODE_HIGHEST or greater

hashCode

Added in API level 26
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 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 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 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.

Returns
int a hash code value for this object.

toString

Added in API level 26
public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.

writeToParcel

Added in API level 26
public void writeToParcel (Parcel parcel, 
                int flags)

Flatten this object in to a Parcel.

Parameters
parcel 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
