Constructor:

Constructor:
public JarEntry(String name) { super(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. exception: `NullPointerException` - if the entry name is `null` exception: `IllegalArgumentException` - if the entry name is longer than 0xFFFF bytes.
public JarEntry(ZipEntry ze) { super(ze); } Creates a new `JarEntry` with fields taken from the specified `ZipEntry` object. Parameters: `ze` - the `ZipEntry` object to create the `JarEntry` from
public JarEntry(JarEntry je) { this((ZipEntry)je); this.attr = je.attr; this.certs = je.certs; this.signers = je.signers; } Creates a new `JarEntry` with fields taken from the specified `JarEntry` object. Parameters: `je` - the `JarEntry` to copy

 public JarEntry(String name) {
        super(name);
}

exception: NullPointerException - if the entry name is null

exception: IllegalArgumentException - if the entry name is longer than 0xFFFF bytes.

ZipEntry

Parameters:

ze - the ZipEntry object to create the JarEntry from

 public JarEntry(JarEntry je) {
        this((ZipEntry)je);
        this.attr = je.attr;
        this.certs = je.certs;
        this.signers = je.signers;
}

Parameters:

je - the JarEntry to copy

Method from java.util.jar.JarEntry Summary:
getAttributes, getCertificates, getCodeSigners

Methods from java.util.zip.ZipEntry:
clone, getComment, getCompressedSize, getCrc, getExtra, getMethod, getName, getSize, getTime, hashCode, isDirectory, setComment, setCompressedSize, setCrc, setExtra, setMethod, setSize, setTime, toString

Methods from java.lang.Object:
clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

Method from java.util.jar.JarEntry Detail:
public Attributes getAttributes() throws IOException { return attr; } Returns the `Manifest` `Attributes` for this entry, or `null` if none.
public Certificate[] getCertificates() { return certs == null ? null : certs.clone(); } 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).
public CodeSigner[] getCodeSigners() { return signers == null ? null : signers.clone(); } 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.
