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

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

open Boolean
equals(other: Any?)

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

open Int

Returns a hash code value for the object.

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)

Flatten this object in to a Parcel.

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

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.

Return
Int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.
Value is either 0 or

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

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.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.
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

Flatten this object in to a Parcel.

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 the following:
