defineClassFromData

protected java.lang.Class defineClassFromData(java.io.File container,
                                              byte[] classData,
                                              java.lang.String className)
                                       throws java.io.IOException

Define a class given its bytes

Overrides:

defineClassFromData in class AntClassLoader

Parameters:

container - the container from which the class data has been read may be a directory or a jar/zip file.

classData - the bytecode data for the class

className - the name of the class

Returns:

the Class instance created from the given data

Throws:

java.io.IOException - if the class data cannot be read.

definePackage

protected void definePackage(java.io.File container,
                             java.lang.String className)
                      throws java.io.IOException

Define the package information associated with a class.

Parameters:

container - the file containing the class definition.

className - the class name of for which the package information is to be determined.

Throws:

java.io.IOException - if the package information cannot be read from the container.

definePackage

protected void definePackage(java.io.File container,
                             java.lang.String packageName,
                             java.util.jar.Manifest manifest)

Define the package information when the class comes from a jar with a manifest

Parameters:

container - the jar file containing the manifest

packageName - the name of the package being defined.

manifest - the jar's manifest

addPathFile

protected void addPathFile(java.io.File pathComponent)
                    throws java.io.IOException

Add a file to the path. This classloader reads the manifest, if available, and adds any additional class path jars specified in the manifest.

Overrides:
