Signature

open class Signature : Parcelable
kotlin.Any
   ↳ android.content.pm.Signature

Opaque, immutable representation of a signing certificate associated with an application package.

This class name is slightly misleading, since it's not actually a signature.

Summary

Inherited constants
Public constructors
Signature(signature: ByteArray!)

Create Signature from an existing raw byte array.
Signature(text: String!)

Create Signature from a text representation previously returned by #toChars or toCharsString().
Public methods
open Int

open Boolean
equals(other: Any?)

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

open ByteArray!

open CharArray!

Encode the Signature as ASCII text.
open CharArray!
toChars(existingArray: CharArray!, outLen: IntArray!)

Encode the Signature as ASCII text in to an existing array.
open String!

Return the result of toChars() as a String.
open Unit
writeToParcel(dest: Parcel, parcelableFlags: Int)
Properties
static Parcelable.Creator<Signature!>

Public constructors

Signature

Added in API level 1
Signature(signature: ByteArray!)

Create Signature from an existing raw byte array.

Signature

Added in API level 1
Signature(text: String!)

Create Signature from a text representation previously returned by #toChars or toCharsString(). Signatures are expected to be a hex-encoded ASCII string.

Parameters
text String!: hex-encoded string representing the signature
Exceptions
java.lang.IllegalArgumentException when signature is odd-length

Public methods

describeContents

Added in API level 1
open fun describeContents(): Int
Return
Int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 1
open fun equals(other: Any?): Boolean

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
obj This value may be null.
Return
Boolean true if this object is the same as the obj argument; false otherwise.

hashCode

Added in API level 1
open fun hashCode(): Int
Return
Int a hash code value for this object.

toByteArray

Added in API level 1
open fun toByteArray(): ByteArray!
Return
ByteArray! the contents of this signature as a byte array.

toChars

Added in API level 1
open fun toChars(): CharArray!

Encode the Signature as ASCII text.

toChars

Added in API level 1
open fun toChars(
    existingArray: CharArray!, 
    outLen: IntArray!
): CharArray!

Encode the Signature as ASCII text in to an existing array.

Parameters
existingArray CharArray!: Existing char array or null.
outLen IntArray!: Output parameter for the number of characters written in to the array.
Return
CharArray! Returns either existingArray if it was large enough to hold the ASCII representation, or a newly created char[] array if needed.

toCharsString

Added in API level 1
open fun toCharsString(): String!

Return the result of toChars() as a String.

writeToParcel

Added in API level 1
open fun writeToParcel(
    dest: Parcel, 
    parcelableFlags: Int
): Unit
Parameters
dest Parcel: The Parcel in which the object should be written. This value cannot be null.
flags Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES

Properties

CREATOR
