Detailed Description

The root UNO class loader.

This class loader is able to load all published URE classes, including the classes representing the published URE UNO types. For consistency, it is important that within each Java UNO environment there is one instance of this class loader that is the defining class loader of all published URE classes (and hence of all unpublished URE classes, too) and of all classes representing UNO types (the published URE UNO types, any unpublished URE UNO types, and any additional UNO types introduced by components; for the latter, addURL may be necessary).

This is an internal, unstable class of the Uno Runtime Environment; it should not be used by client code.

Available since: \n UDK 3.2.0

Constructor & Destructor Documentation

UnoClassLoader()

com.sun.star.lib.unoloader.UnoClassLoader.UnoClassLoader ( URL  base, URL[]  classPath, ClassLoader  parent  ) throws MalformedURLException

inline

Instantiates the root UNO class loader.

Parameters

base	a base URL relative to which the URE JARs (java_uno.jar and libreoffice.jar) can be found; must not be null.
classPath	an array of URLs that form the class path of this class loader; may be null, which is the same as an empty array. The URLs are interpreted in the same way as the arguments of a URLClassLoader.
parent	the parent class loader for delegation.

Exceptions

MalformedURLException

if the given base URL is malformed.

execute()

void com.sun.star.lib.unoloader.UnoClassLoader.execute ( URL  jar, String[]  arguments  ) throws IOException, ClassNotFoundException, NoSuchMethodException, InvocationTargetException

inline

Executes a UNO JAR.

Parameters

jar	the URL of a UNO JAR that specifies a Main-Class; must not be null.
arguments	any arguments passed to the main method of the specified Main-Class of the given JAR jar; must not be null.

Exceptions

IOException	if there are any problems processing the given JAR jar.
ClassNotFoundException	if the given JAR jar does not specify a Main-Class, or if the specified Main-Class cannot be found.
NoSuchMethodException	if the specified Main-Class of the given JAR jar does not have an appropriate main method.
InvocationTargetException	if an exception occurs while executing the main method of the specified Main-Class of the given JAR jar.

getClassLoader()

ClassLoader com.sun.star.lib.unoloader.UnoClassLoader.getClassLoader ( URL  jar, Attributes  mainAttributes  ) throws MalformedURLException

inline

Obtains a class loader for a UNO JAR.

Parameters

jar	the URL of a UNO JAR; must not be null.
mainAttributes	represents the main section of the manifest of the given JAR jar; null if the given JAR does not have a manifest. (This redundant parameter is there for performance reasons, as typically the caller of this method already has this information available.)

Returns

an appropriate class loader; will never be null.

Exceptions

MalformedURLException

if the given jar URL or any of the UNO-Type-Path URLs specified in the given JAR are malformed.

getJarMainAttributes()

static Attributes com.sun.star.lib.unoloader.UnoClassLoader.getJarMainAttributes ( URL  jar ) throws IOException

inlinestatic

Obtains the main section of the manifest of a JAR.

Parameters

jar	the URL of a JAR; must not be null.

Returns

the representation of the main section of the manifest of the given JAR jar, or null if the given JAR does not have a manifest.

Exceptions

IOException

if there are any problems processing the given JAR jar.
