类 SignedJarWriter

  • 所有已实现的接口:
    java.lang.AutoCloseable, DataEntryWriter
    public class SignedJarWriter
extends JarWriter
    This JarWriter sends data entries to a given jar file, automatically adding a manifest file and signing it with JAR signature scheme v1.

    You'll typically wrap a ZipWriter or one of its extensions: 

         new SignedApkWriter(privateKeyEntry, new ZipWriter(...))

        参数:
        dataEntry - the data entry for which the output stream is to be created.
        返回:
        the output stream. The stream may be null to indicate that the data entry should not be written.
        抛出:
        java.io.IOException
