Constructor Detail

CodeSigner

public CodeSigner(CertPath signerCertPath,
                  Timestamp timestamp)

Constructs a CodeSigner object.

Parameters:: signerCertPath - The signer's certificate path. It must not be null.; timestamp - A signature timestamp. If null then no timestamp was generated for the signature.
Throws:: NullPointerException - if signerCertPath is null.

Method Detail

getSignerCertPath

public CertPath getSignerCertPath()

Returns the signer's certificate path.

Returns:: A certificate path.

getTimestamp

public Timestamp getTimestamp()

Returns the signature timestamp.

Returns:: The timestamp or null if none is present.

hashCode

public int hashCode()

Returns the hash code value for this code signer. The hash code is generated using the signer's certificate path and the timestamp, if present.

Overrides:: hashCode in class Object

Returns:: a hash code value for this code signer.
See Also:: Object.equals(java.lang.Object), Hashtable

equals

public boolean equals(Object obj)

Tests for equality between the specified object and this code signer. Two code signers are considered equal if their signer certificate paths are equal and if their timestamps are equal, if present in both.

Overrides:: equals in class Object

Parameters:: obj - the object to test for equality with this object.
Returns:: true if the objects are considered equal, false otherwise.
See Also:: Object.hashCode(), Hashtable

toString

public String toString()

Returns a string describing this code signer.

Overrides:: toString in class Object

Returns:: A string comprising the signer's certificate and a timestamp, if present.
