JarVerifierStream
public class JarVerifierStream extends ZipInputStream (Code)
This is OBSOLETE. DO NOT USE THIS. Use java.util.jar.JarEntry.getCertificates instead. It has to stay here because some apps (namely HJ and HJV) call directly into it. This class is stripped down greatly from JDK 1.1.x.

Inner Class :static class CertCache


Constructor Summary
public  JarVerifierStream(InputStream is)
     construct a JarVerfierStream from an input stream.

Method Summary
public  voidclose()
    
public  voidcloseEntry()
    
public  EnumerationgetBlocks()
     Returns an enumeration of PKCS7 blocks.
protected  VectorgetIds(Certificate[] certs)
    
public  sun.tools.jar.ManifestgetManifest()
     Convert java.util.jar.Manifest object to a sun.tools.jar.Manifest object.
public  HashtablegetNameToHash()
     This method used to be called by various versions of AppletResourceLoader, even though they didn't do anything with the result.

Constructor Detail
JarVerifierStream
public JarVerifierStream(InputStream is) throws IOException(Code)
construct a JarVerfierStream from an input stream.




Method Detail
close
public void close() throws IOException(Code)



closeEntry
public void closeEntry() throws IOException(Code)



getBlocks
public Enumeration getBlocks()(Code)
Returns an enumeration of PKCS7 blocks. This looks bogus, but Hotjava just checks to see if enumeration is not null to see if anything was signed!



getIds
protected Vector getIds(Certificate[] certs)(Code)
Returns the Identity vector for the given array of Certificates



getManifest
public sun.tools.jar.Manifest getManifest()(Code)
Convert java.util.jar.Manifest object to a sun.tools.jar.Manifest object.



getNameToHash
public Hashtable getNameToHash()(Code)
This method used to be called by various versions of AppletResourceLoader, even though they didn't do anything with the result. We leave them and return null for backwards compatability.



getNextEntry
public synchronized ZipEntry getNextEntry() throws IOException(Code)
This method scans to see which entry we're parsing and keeps various state information depending on what type of file is being parsed. Files it treats specially are:
  • Manifest files. At any point, this stream can be queried for a manifest. If it is present, a Manifest object will be returned.
  • Block Signature file. Like with the manifest, the stream can be queried at any time for all blocks parsed thus far.



getVerifiedSignatures
public Hashtable getVerifiedSignatures()(Code)
Returns a Hashtable mapping filenames to vectors of identities.



read
public int read() throws IOException(Code)
read a single byte.



read
public int read(byte[] b, int off, int len) throws IOException(Code)
read an array of bytes.
