### Constructor Detail

#### JarEntry

    public JarEntry(String name)

Creates a new `JarEntry` for the specified JAR file entry name.

Parameters:
  `name` - the JAR file entry name
Throws:
  `NullPointerException` - if the entry name is `null`
  `IllegalArgumentException` - if the entry name is longer than 0xFFFF bytes.

#### JarEntry

    public JarEntry(ZipEntry ze)

Creates a new `JarEntry` with fields taken from the specified `ZipEntry` object.

Parameters:
  `ze` - the `ZipEntry` object to create the `JarEntry` from

#### JarEntry

    public JarEntry(JarEntry je)

Creates a new `JarEntry` with fields taken from the specified `JarEntry` object.

Parameters:
  `je` - the `JarEntry` to copy

### Method Detail

#### getAttributes

    public Attributes getAttributes()
                             throws IOException

Returns the `Manifest` `Attributes` for this entry, or `null` if none.

Returns:
  the `Manifest` `Attributes` for this entry, or `null` if none
Throws:
  `IOException`

#### getCertificates

    public Certificate[] getCertificates()

Returns the `Certificate` objects for this entry, or `null` if none. This method can only be called once the `JarEntry` has been completely verified by reading from the entry input stream until the end of the stream has been reached. Otherwise, this method will return `null`.

The returned certificate array comprises all the signer certificates that were used to verify this entry. Each signer certificate is followed by its supporting certificate chain (which may be empty). Each signer certificate and its supporting certificate chain are ordered bottom-to-top (i.e., with the signer certificate first and the (root) certificate authority last).

Returns:
  the `Certificate` objects for this entry, or `null` if none.

#### getCodeSigners

    public CodeSigner[] getCodeSigners()

Returns the `CodeSigner` objects for this entry, or `null` if none. This method can only be called once the `JarEntry` has been completely verified by reading from the entry input stream until the end of the stream has been reached. Otherwise, this method will return `null`.

The returned array comprises all the code signers that have signed this entry.

Returns:
  the `CodeSigner` objects for this entry, or `null` if none.
