Method Detail

findClassback to summary
protected Class<?> findClass(String name) throws ClassNotFoundException

Overrides java.lang.ClassLoader.findClass.

Doc from java.lang.ClassLoader.findClass.

Finds the class with the specified binary name. This method should be overridden by class loader implementations that follow the delegation model for loading classes, and will be invoked by the loadClass method after checking the parent class loader for the requested class.

Parameters
name:String

The binary name of the class

Returns:Class<?>

The resulting Class object

Exceptions
ClassNotFoundException:
If the class could not be found
findResourceback to summary
protected URL findResource(String name)

Overrides java.lang.ClassLoader.findResource.

Doc from java.lang.ClassLoader.findResource.

Finds the resource with the given name. Class loader implementations should override this method.

For resources in named modules then the method must implement the rules for encapsulation specified in the Module getResourceAsStream method. Additionally, it must not find non-".class" resources in packages of named modules unless the package is opened unconditionally.

Parameters
name:String

The resource name

Returns:URL

URL object for reading the resource; null if the resource could not be found, a URL could not be constructed to locate the resource, the resource is in a package that is not opened unconditionally, or access to the resource is denied by the security manager.

@Override
getResourcesback to summary
public Enumeration<URL> getResources(String name) throws IOException

Overrides java.lang.ClassLoader.getResources.

Doc from java.lang.ClassLoader.getResources.

Finds all the resources with the given name. A resource is some data (images, audio, text, etc) that can be accessed by class code in a way that is independent of the location of the code.

The name of a resource is a /-separated path name that identifies the resource.

Resources in named modules are subject to the encapsulation rules specified by Module.getResourceAsStream. Additionally, and except for the special case where the resource has a name ending with ".class", this method will only find resources in packages of named modules when the package is opened unconditionally (even if the caller of this method is in the same module as the resource).

Parameters
name:String

The resource name

Returns:Enumeration<URL>

An enumeration of URL objects for the resource. If no resources could be found, the enumeration will be empty. Resources for which a URL cannot be constructed, are in a package that is not opened unconditionally, or access to the resource is denied by the security manager, are not returned in the enumeration.
