Timestamp

public Timestamp(Date timestamp,
                 CertPath signerCertPath)

Constructs a Timestamp.

参数:

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.

抛出:

NullPointerException - if timestamp or signerCertPath is null.

方法详细资料

getTimestamp

public Date getTimestamp()

Returns the date and time when the timestamp was generated.

返回:

The timestamp's date and time.

getSignerCertPath

public CertPath getSignerCertPath()

Returns the certificate path for the Timestamping Authority.

返回:

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.

覆盖:

hashCode 在类中 Object

返回:

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.

覆盖:

equals 在类中 Object

参数:

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

返回:

true if the timestamp are considered equal, false otherwise.

toString

public String toString()

Returns a string describing this timestamp.

覆盖:

toString 在类中 Object

返回:

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