Class Timestamp

java.lang.Object extended by java.security.Timestamp

All Implemented Interfaces:

public final class Timestamp

This class encapsulates information about a signed timestamp. It is immutable. It includes the timestamp's date and time as well as information about the Timestamping Authority (TSA) which generated and signed the timestamp.

Since:

1.5

Constructor Detail

Timestamp

public Timestamp(Date timestamp, CertPath signerCertPath)

Constructs a Timestamp.

Parameters:

timestamp - is the timestamp's date and time. It must not be null.

signerCertPath - is the TSA's certificate path. It must not be null.

Throws:

[NullPointerException](../../java/lang/NullPointerException.html "class in java.lang") - if timestamp or signerCertPath is null.

Method Detail

getTimestamp

public Date getTimestamp()

Returns the date and time when the timestamp was generated.

Returns:

The timestamp's date and time.

getSignerCertPath

public CertPath getSignerCertPath()

Returns the certificate path for the Timestamping Authority.

Returns:

The TSA's certificate path.

hashCode

public int hashCode()

Returns the hash code value for this timestamp. The hash code is generated using the date and time of the timestamp and the TSA's certificate path.

Overrides:

[hashCode](../../java/lang/Object.html#hashCode%28%29) in class [Object](../../java/lang/Object.html "class in java.lang")

Returns:

a hash code value for this timestamp.

equals

public boolean equals(Object obj)

Tests for equality between the specified object and this timestamp. Two timestamps are considered equal if the date and time of their timestamp's and their signer's certificate paths are equal.

Overrides:

[equals](../../java/lang/Object.html#equals%28java.lang.Object%29) in class [Object](../../java/lang/Object.html "class in java.lang")

Parameters:

obj - the object to test for equality with this timestamp.

Returns:

true if the timestamp are considered equal, false otherwise.

toString

public String toString()

Returns a string describing this timestamp.

Overrides:

[toString](../../java/lang/Object.html#toString%28%29) in class [Object](../../java/lang/Object.html "class in java.lang")

Returns:

A string comprising the date and time of the timestamp and its signer's certificate.
