Field Detail

jarFileFactory

private static final JarFile jarFileFactory

updateLoader

private UpdateLoader updateLoader

---

jf

private JarFile jf

---

vs

private org.apache.derby.iapi.services.stream.HeaderPrintWriter vs

Constructor Detail

JarLoader

JarLoader(UpdateLoader updateLoader,
          java.lang.String[] name,
          org.apache.derby.iapi.services.stream.HeaderPrintWriter vs)

Method Detail

initialize

void initialize()

---

loadClass

public java.lang.Class loadClass(java.lang.String className,
                                 boolean resolve)
                          throws java.lang.ClassNotFoundException

Handle all requests to the top-level loader.

---

getResourceAsStream

public java.io.InputStream getResourceAsStream(java.lang.String name)

Description copied from class: java.lang.ClassLoader

Get a resource as stream using this classloader or one of its parents. First calls getResource() and if that returns a URL to the resource then it calls and returns the InputStream given by URL.openStream().

Subclasses should not override this method but should override findResource() which is called by this method.

---

getJarName

final java.lang.String getJarName()

---

loadClassData

java.lang.Class loadClassData(java.lang.String className,
                              java.lang.String jvmClassName,
                              boolean resolve)

---

getStream

java.io.InputStream getStream(java.lang.String name)

Get an InputStream for the given resource.

---

loadClassDataFromJar

private java.lang.Class loadClassDataFromJar(java.lang.String className,
                                             java.lang.String jvmClassName,
                                             boolean resolve)
                                      throws java.io.IOException

---

loadClassData

private java.lang.Class loadClassData(java.io.InputStream in,
                                      java.lang.String className,
                                      java.lang.String jvmClassName,
                                      boolean resolve)
                               throws java.io.IOException

---

loadClassData

private java.lang.Class loadClassData(java.util.zip.ZipEntry ze,
                                      java.io.InputStream in,
                                      java.lang.String className,

                               throws java.io.IOException

---

checkLoaded

java.lang.Class checkLoaded(java.lang.String className,
                            boolean resolve)

---

load

private java.lang.Object load()

---

setInvalid

JarFile setInvalid(boolean newJarFile)

---

getRawStream

private java.io.InputStream getRawStream(java.util.zip.ZipFile zip,
                                         java.lang.String name)

Get a stream directly from a ZipFile. In this case we can safely return the stream directly. It's a new stream set up by the zip code to read just the contents of this entry.

---

getRawStream

private java.io.InputStream getRawStream(java.io.InputStream in,
                                         java.lang.String name)

Get a stream from a zip file that is itself a stream. Here we need to get the size of the zip entry and put a limiting stream around it. Otherwise the caller would end up reading the entire zip file!
