java.security
Class Timestamp
java.lang.Object
java.security.Timestamp
-
All Implemented Interfaces:
-
Serializable
-
public final class Timestamp
- extends Object
- implements Serializable
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.
-

-
1.5

Serialized Form
Method Summary boolean
equals(Object obj)
Tests for equality between the specified object and this timestamp. CertPath
getSignerCertPath()
Returns the certificate path for the Timestamping Authority. Date
getTimestamp()
Returns the date and time when the timestamp was generated. int
hashCode()
Returns the hash code value for this timestamp. String
toString()
Returns a string describing this timestamp. 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
- if timestamp or signerCertPath is null.
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
in class Object
-
-
Returns:
-
a hash code value for this timestamp.
-

-
Object.equals(java.lang.Object)
, Hashtable
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
in class Object
-
-
Parameters:
-
obj
- the object to test for equality with this timestamp.
-
Returns:
-
true if the timestamp are considered equal, false otherwise.
-

, Hashtable
toString
public String toString()
-
Returns a string describing this timestamp.
-
-
Overrides:
-
toString
in class Object
-
-
Returns:
-
A string comprising the date and time of the timestamp and its signer's certificate.
