JarEntryjava.util.jar

Java 1.2cloneable

This class extends java.util.zip.ZipEntry; it represents a single file in a JAR archive and the manifest attributes and digital signatures associated with that file. JarEntry objects can be read from a JAR file with JarFile or JarInputStream, and they can be written to a JAR file with JarOutputStream. Use getAttributes( ) to obtain the Attributes for the entry. Use getCertificates( ) to obtain a java.security.cert.Certificate array that contains the certificate chains for all digital signatures associated with the file. In Java 5.0, this digital signature information may be more conveniently retrieved as an array of CodeSigner objects.
