Member Function Documentation

virtual RClass acdk::lang::ClassLoader::defineClass (  IN(RString)  name, IN(RbyteArray)  b, int  off, int  len )  [virtual]

This method is not implemented.

virtual RClass acdk::lang::ClassLoader::findClass (  IN(RString)  name, bool  nothrow = false )  throw ( RClassNotFoundException ) [virtual]

Try to find a class by name. If the class currently is not loaded it uses the acdk::lang::SharedLibrary to find a shared library which mapps the full class name or parts of the namespace. It uses following pattern: findClass(acdk::security::GeneralSecurityException) try to load following librares: Unix: acdk_security_GeneralSecurityException.so acdk_security.so acdk.so Windows (Debug-Release): acdk_security_GeneralSecurityException_d.dll acdk_security_d.dll acdk_d.dll See also: also ClassLoader::findLibrary Parameters: name  of the class in one of following forms: acdk::security::GeneralSecurityException acdk.security.GeneralSecurityException acdk/security/GeneralSecurityException nothrow,if  true method does't throw ex if not found Returns: the loaded class if found otherwise Nil Reimplemented in acdk::cfgscript::ScriptClassLoader.

virtual RString acdk::lang::ClassLoader::findLibrary (  IN(RString)  libname  )  [virtual]

Try to find and load a library corresponding the package name. this method consul the property acdk.lang.ClassLoaderAliase if there are any aliase. It checks param libname starts with a key of an alias. if yes it replaces the beginning of libname with the value defined in the property. Parameters: libname  name of the library without extends For example acdk_security try to load acdk_security_d.dll (Windows Debug) or acdk_security.so (Unix) Returns: the name of the loaded library. Otherwise Nil.

virtual RString acdk::lang::ClassLoader::findLibrary2 (  IN(RString)  libname  )  [virtual]

Parameters: libname  name of the library without extends For example acdk_security try to load acdk_security_d.dll (Windows Debug) or acdk_security.so (Unix) Returns: the name of the loaded library. Otherwise Nil.

virtual RClass acdk::lang::ClassLoader::findLoadedClass (  IN(RString)  name, bool  nothrow = true )  throw ( RClassNotFoundException ) [virtual]

find a class, which is already loaded Parameters: name  of the class Returns: the Class corresponds to the name. Nil if the class is not loaded Reimplemented in acdk::cfgscript::ScriptClassLoader.

virtual acdk::io::RFile acdk::lang::ClassLoader::findResource (  IN(RString)  name  )  [virtual]

return a ressource located by name otherwise Nil Parameters: name  identifies a file resource like acdk/locale/LocaleInfo.properties

virtual acdk::util::RIterator acdk::lang::ClassLoader::findResources (  IN(RString)  name  )  [virtual]

return iterator to acdk::io::RFile Reimplemented in acdk::cfgscript::ScriptClassLoader.

virtual RClass acdk::lang::ClassLoader::findSystemClass (  IN(RString)  name  )  throw ( RClassNotFoundException ) [virtual]

just return findClass(name)

virtual RPackage acdk::lang::ClassLoader::getPackage (  IN(RString)  name  )  [virtual]

Method is not implemented.

virtual RPackageArray acdk::lang::ClassLoader::getPackages (   )  [virtual]

Method is not implemented.

virtual RClassLoader acdk::lang::ClassLoader::getParent (   )  [inline, virtual]

Returns: the parent Classloader if any otherwise Nil

virtual acdk::io::RFile acdk::lang::ClassLoader::getResource (  IN(RString)  name  )  [virtual]

Different to Java this method returns a File (which may also contain URL).

virtual acdk::io::RReader acdk::lang::ClassLoader::getResourceAsStream (  IN(RString)  name  )  [virtual]

is equaly to getResource(name)->getReader()

virtual acdk::util::RIterator acdk::lang::ClassLoader::getResources (  IN(RString)  name  )  [virtual]

return iterator to acdk::io::RFile

RClassLoader acdk::lang::ClassLoader::getSystemClassLoader (   )  [static]

The normal ClassLoader which loads native ACDK classes and libraries. Returns: the SystemClassLoader

acdk::io::RFile acdk::lang::ClassLoader::getSystemResource (  IN(RString)  name  )  [static]

acdk::io::RReader acdk::lang::ClassLoader::getSystemResourceAsStream (  IN(RString)  name  )  [static]

returns getSystemClassLoader()->getResourceAsStream()

acdk::util::RIterator acdk::lang::ClassLoader::getSystemResources (  IN(RString)  name  )  [static]

return getSystemClassLoader()->getSystemResources(name)

virtual RClass acdk::lang::ClassLoader::loadClass (  IN(RString)  name, bool  resolve )  throw ( RClassNotFoundException ) [virtual]

Parameters: resolve  has no effect

virtual RClass acdk::lang::ClassLoader::loadClass (  IN(RString)  name  )  throw ( RClassNotFoundException ) [virtual]

virtual bool acdk::lang::ClassLoader::loadClassLibrary (  IN(RString)  classname  )  [virtual]

Reimplemented in acdk::cfgscript::ScriptClassLoader.

virtual bool acdk::lang::ClassLoader::loadDmiProxyLibrary (  IN(RString)  classname  )  [virtual]

try to load dmi proxy library of given class Returns: false if no meta info library can be found Reimplemented in acdk::cfgscript::ScriptClassLoader.

bool acdk::lang::ClassLoader::loadExtInfoLibrary (  IN(RString)  classname, IN(RString)  sufix )  [protected]

virtual bool acdk::lang::ClassLoader::loadMetaInfoLibrary (  IN(RString)  classname  )  [virtual]

try to load metainfo library of given class Returns: false if no meta info library can be found Reimplemented in acdk::cfgscript::ScriptClassLoader.

virtual acdk::lang::reflect::RUnit acdk::lang::ClassLoader::loadUnit (  IN(RString)  name  )  throw ( RClassNotFoundException ) [virtual]

try to load Unit. Tries to load also shared library

acdk::lang::ClassLoader::OUT (  RClassLoader   )  [static, protected]

void acdk::lang::ClassLoader::registerClassLoader (  IN(RClassLoader)  classLoader  )  [inline]

virtual void acdk::lang::ClassLoader::resolveClass (  IN(RClass)  c  )  [virtual]

Method has no functionality. Reimplemented in acdk::cfgscript::ScriptClassLoader.

virtual void acdk::lang::ClassLoader::setSigners (  IN(RClass)  c, IN(RObjectArray)  signers )  [virtual]
