From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) 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() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, 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 millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Constructors

public JarEntry (String name)

Added in API level 1

Creates a new JarEntry named name.

Parameters

name	The name of the new `JarEntry`.

public JarEntry (ZipEntry entry)

Added in API level 1

Creates a new JarEntry using the values obtained from entry.

Parameters

entry	The ZipEntry to obtain values from.

public JarEntry (JarEntry je)

Added in API level 1

Create a new JarEntry using the values obtained from the argument.

Parameters

je	The `JarEntry` to obtain values from.

Public Methods

public Attributes getAttributes ()

Added in API level 1

Returns the Attributes object associated with this entry or null if none exists.

Returns

the Attributes for this entry.

Throws

IOException	If an error occurs obtaining the `Attributes`.

public Certificate[] getCertificates ()

Added in API level 1

Returns an array of Certificate Objects associated with this entry or null if none exists. Make sure that the everything is read from the input stream before calling this method, or else the method returns null.

This method returns all the signers' unverified chains concatenated together in one array. To know which certificates were tied to the private keys that made the signatures on this entry, see getCodeSigners() instead.

public CodeSigner[] getCodeSigners ()

Added in API level 1

Returns the code signers for the digital signatures associated with the JAR file. If there is no such code signer, it returns null. Make sure that the everything is read from the input stream before calling this method, or else the method returns null.

Only the digital signature on the entry is cryptographically verified. None of the certificates in the the CertPath returned from getSignerCertPath() are verified and must be verified by the caller if needed. See CertPathValidator for more information.

Returns

an array of CodeSigner for this JAR entry.
