PackagePolicy

PACKAGE_POLICY_ALLOWLIST

public static final int PACKAGE_POLICY_ALLOWLIST

PackagePolicy type indicator for PackagePolicy

This constant indicates that all packages are denied except for the packages returned by PackagePolicy#getPackageNames(), which acts as an allowlist.

Constant Value: 3 (0x00000003)

PACKAGE_POLICY_ALLOWLIST_AND_SYSTEM

public static final int PACKAGE_POLICY_ALLOWLIST_AND_SYSTEM

PackagePolicy type indicator for PackagePolicy

This constant indicates system packages are allowed in addition to the packages returned by PackagePolicy#getPackageNames(), which acts as an allowlist.

Functions that accept PackagePolicy will further clarify how this policy is interpreted.

Constant Value: 2 (0x00000002)

PACKAGE_POLICY_BLOCKLIST

public static final int PACKAGE_POLICY_BLOCKLIST

PackagePolicy type indicator for PackagePolicy

This constant indicates that all packages are allowed except for the packages returned by PackagePolicy#getPackageNames(), which acts as a denylist.

Constant Value: 1 (0x00000001)

CREATOR

public static final Creator<PackagePolicy> CREATOR

PackagePolicy

public PackagePolicy (int policyType)

Create the package policy

PackagePolicy

public PackagePolicy (int policyType, 
                Set<String> packageNames)

Create the package policy

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.

equals

public boolean equals (Object thatObject)

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.

getPackageNames

public Set<String> getPackageNames ()

Returns the list of packages to use as an allow/deny list based on policy type

getPolicyType

public int getPolicyType ()

Returns the current policy type

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 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. (The hashCode may or may not be implemented as some function of an object's memory address at some point in time.)

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.
