Enum Constant Detail

PROOF_OF_EXISTENCE

public static final TimeSource PROOF_OF_EXISTENCE

Proof of Existence

A proof of existence is evidence that proves that an object (a certificate, a CRL, signature value, hash value, etc.) existed at a specific time, which may be a time in the past. The presence of a given object at the current time is a proof of its existence at the current time. A suitable way of providing proof of existence of an object at a time in the past is to generate a time-stamp for that object.

EXPIRED_TIME_STAMP

public static final TimeSource EXPIRED_TIME_STAMP

Expired time stamp

An expired time-stamp was used. Note that for expired time-stamps revocation information checks might not be possible.

SIGNATURE_TIME

public static final TimeSource SIGNATURE_TIME

Signature time

Use the claimed (untrusted) time of the signature.

Method Detail

values

public static TimeSource[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TimeSource c : TimeSource.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TimeSource valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
