Method Detail

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

Overrides java.lang.ClassLoader.findClass.

Implements ClassLoader#findClass(String).

Notice that, although nowhere documented, no more than one thread at a time calls this method, because ClassLoader#loadClass(java.lang.String) is synchronized.

Parameters
name:String

Doc from java.lang.ClassLoader.findClass.

The binary name of the class

Returns:Class<?>

Doc from java.lang.ClassLoader.findClass.

The resulting Class object

Annotations
@Override
Exceptions
ClassNotFoundException:

Doc from java.lang.ClassLoader.findClass.

If the class could not be found

getResourceAsStreamback to summary
public InputStream getResourceAsStream(String name)

Overrides java.lang.ClassLoader.getResourceAsStream.

Doc from java.lang.ClassLoader.getResourceAsStream.

Returns an input stream for reading the specified resource.

The search order is described in the documentation for getResource(String).

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.

Parameters
name:String

The resource name

Returns:InputStream

An input stream for reading the resource; null if the resource could not be found, the resource is in a package that is not opened unconditionally, or access to the resource is denied by the security manager.
