Detailed Description

Main ClassLoader for Java <-> Qore and Java <-> Python integration.

This ClassLoader supports dynamic imports from Qore and Java using the following special packages:

• python.[path...]: indicates that the given path should be imported from Python to Java (after being imported to Qore if necessary).
• pythonmod.mod.[path...]: indicates that the given path should be mapped to Qore namespaces and/or classes after loading the Python module mod and importing into Qore; the Java package segments after pythonmod.mod. are then converted to the equivalent Qore namespace path
• qore: indicates that the given path should be mapped to Qore namespaces and/or classes; the Java package segments after qore. are then converted to the equivalent Qore namespace path
• qoremod.mod.[path...]: indicates that the given path should be mapped to Qore namespaces and/or classes after loading the Qore module mod; the Java package segments after qoremod.mod. are then converted to the equivalent Qore namespace path

Constructor & Destructor Documentation

QoreURLClassLoader()

org.qore.jni.QoreURLClassLoader.QoreURLClassLoader ( ClassLoader  parent )

inline

constructor for using this class as the boot classloader

For example, starting Java like: java -cp xxx -Djava.system.class.loader=org.qore.jni.QoreURLClassLoader ... will result in this constructor being called

Member Function Documentation

add()

void org.qore.jni.QoreURLClassLoader.add ( final String  qualifiedClassName, final QoreJavaFileObject  javaFile  )

inline

Add a class name/JavaFileObject mapping

Parameters

qualifiedClassName	the name
javaFile	the file associated with the name

addWildcard()

void org.qore.jni.QoreURLClassLoader.addWildcard ( File  dir, String  nam  )

inline

Adds a set of files using a generic base name to this loader's classpath. See addClassPath(String) for details of the generic base name.

checkLoadedClass()

Class<?> org.qore.jni.QoreURLClassLoader.checkLoadedClass ( String  bin_name )

inline

Check if the class is loaded in this class loader or in the parent if it's a QoreURLClassLoader

Parameters

bin_name

the class to check

Returns

the class if it's loaded

clearCompilationCache()

void org.qore.jni.QoreURLClassLoader.clearCompilationCache ( )

inline

Clears the compilation cache after compiling

files()

Collection< QoreJavaFileObject > org.qore.jni.QoreURLClassLoader.files ( )

inline

Returns

An collection of QoreJavaFileObject instances for the classes in the class loader.

loadClass()

Class<?> org.qore.jni.QoreURLClassLoader.loadClass ( String  bin_name ) throws ClassNotFoundException

inline

Loads classes; returns pending classes injected by the jni module or the compiler
