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.

Public constructors
Signature
Signature(signature: ByteArray!)
Create Signature from an existing raw byte array.
Signature
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
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
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 returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
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
open fun hashCode(): Int
Return | |
---|---|
Int |
a hash code value for this object. |
toByteArray
open fun toByteArray(): ByteArray!
Return | |
---|---|
ByteArray! |
the contents of this signature as a byte array. |
toChars
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
open fun toCharsString(): String!
Return the result of toChars()
as a String.
writeToParcel
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 |
