- 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 - if an I/O error has occurred
  - 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.
