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
- 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
in classObject
- Returns:
- a hash code value for this timestamp.

Object.equals(java.lang.Object)
,System.identityHashCode(java.lang.Object)
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 classObject
- 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.
