CodeSigner

AI-generated Key Takeaways

• The CodeSigner class in Java encapsulates information about a code signer, including their certificate path and optional timestamp.

• It provides methods to access the signer's certificate path and timestamp, as well as methods for equality comparison and hash code generation.

• CodeSigner objects are immutable, meaning their state cannot be changed after creation.

• Instances of CodeSigner are created using a constructor that takes the signer's certificate path and an optional timestamp.

public final class CodeSigner extends Object
implements Serializable

This class encapsulates information about a code signer. It is immutable.

Public Constructor Summary

CodeSigner(CertPath signerCertPath, Timestamp timestamp) Constructs a CodeSigner object.

Public Method Summary

boolean	equals(Object obj) Tests for equality between the specified object and this code signer.
CertPath	getSignerCertPath() Returns the signer's certificate path.
Timestamp	getTimestamp() Returns the signature timestamp.
int	hashCode() Returns the hash code value for this code signer.
String	toString() Returns a string describing this code signer.

Inherited Method Summary

From class java.lang.Object

Object	clone() Creates and returns a copy of this Object.
boolean	equals(Object obj) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of Class that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

Public Constructors

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.

Public Methods

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.

Parameters

obj	the object to test for equality with this object.

Returns

• true if the objects are considered equal, false otherwise.

public CertPath getSignerCertPath ()

Returns the signer's certificate path.

Returns

• A certificate path.

public Timestamp getTimestamp ()

Returns the signature timestamp.

Returns

• The timestamp or null if none is present.

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.

Returns

• a hash code value for this code signer.

public String toString ()

Returns a string describing this code signer.

Returns

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