• Field Detail

  • CREATOR

    public static final Parcelable.Creator<Signature> CREATOR

• Constructor Detail

  • Signature

    public Signature(byte[] signature)

    Create Signature from an existing raw byte array.

  • Signature

    public Signature(String text)

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

    Parameters:

    text - hex-encoded string representing the signature

    Throws:

    IllegalArgumentException - when signature is odd-length

• Method Detail

  • toChars

    public char[] toChars()

    Encode the Signature as ASCII text.

  • toChars

    public char[] toChars(char[] existingArray,
                 int[] outLen)

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

    Parameters:

    existingArray - Existing char array or null.

    outLen - Output parameter for the number of characters written in to the array.

    Returns:

    Returns either existingArray if it was large enough to hold the ASCII representation, or a newly created char[] array if needed.

  • toCharsString

    public String toCharsString()

    Return the result of toChars() as a String.

  • toByteArray

    public byte[] toByteArray()

    Returns:

    the contents of this signature as a byte array.

  • getPublicKey

    public PublicKey getPublicKey()
                           throws CertificateException

    Returns the public key for this signature.

    Throws:

    CertificateException - when Signature isn't a valid X.509 certificate; shouldn't happen.

  • equals

    public boolean equals(Object obj)

    Description copied from class: Object
    Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

    The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

    The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

    Overrides:

    equals in class Object

    Parameters:

    obj - the object to compare this instance with.

    Returns:

    true if the specified object is equal to this Object; false otherwise.

    See Also:

    Object.hashCode()

  • hashCode

    public int hashCode()

    Description copied from class: Object
    Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

    Note that hash values must not change over time unless information used in equals comparisons also changes.

    See Writing a correct hashCode method if you intend implementing your own hashCode method.

    Overrides:

    hashCode in class Object

    Returns:

    this object's hash code.

    See Also:

    Object.equals(java.lang.Object)

  • describeContents

    public int describeContents()

    Description copied from interface: Parcelable
    Describe the kinds of special objects contained in this Parcelable's marshalled representation.

    Specified by:

    describeContents in interface Parcelable

    Returns:

    a bitmask indicating the set of special object types marshalled by the Parcelable.

  • writeToParcel

    public void writeToParcel(Parcel dest,
                     int parcelableFlags)

    Description copied from interface: Parcelable
    Flatten this object in to a Parcel.

    Specified by:

    writeToParcel in interface Parcelable

    Parameters:

    dest - The Parcel in which the object should be written.

    parcelableFlags - Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
