org.python.core .JavaImportHelper

JavaImportHelper
public class JavaImportHelper (Code)
	Helper class handling the VM specific java package detection.

Method Summary

protected static boolean

isLoadedPackage(String packageName)
Check if a java package is already known to the VM.

protected static boolean

tryAddPackage(String packageName, PyObject fromlist)
Try to add the java package.

This is handy in cases where the package scan cannot run, or when the initial classpath does not contain all .jar files (such as in J2EE containers).

There is some self-healing in the sense that a correct, explicit import of a java class will succeed even if sys.modules already contains a Py.None entry for the corresponding java package.
Parameters:
packageName - The dotted name of the java package
Parameters:
fromlist - A tuple with the from names to import.

Method Detail

isLoadedPackage
protected static boolean isLoadedPackage(String packageName)(Code)
	Check if a java package is already known to the VM. May return `false` even if the given package name is a valid java package ! Parameters: packageName - `true` if the package with the given name is already loaded by the VM, `false`otherwise.

tryAddPackage

protected static boolean tryAddPackage(String packageName, PyObject fromlist)(Code)

Try to add the java package.

This is handy in cases where the package scan cannot run, or when the initial classpath does not contain all .jar files (such as in J2EE containers).
