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

Annotations
@Override
Exceptions
ClassNotFoundException:
If the class could not be found

findResourceback to summary
protected URL findResource(String res)

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
res: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.

Annotations
@Override

protected Enumeration<URL> findResources(String res) throws IOException

Overrides java.lang.ClassLoader.findResources.

Doc from java.lang.ClassLoader.findResources.

Returns an enumeration of URL objects representing all the resources 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
res: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.

Annotations
@Override
Exceptions
IOException:
If I/O errors occur

private byte[] getBytesFromInputStream(InputStream input, int size)

Returns a byte[] with the contents read from an InputStream. The stream is closed after reading the bytes.

Parameters
input:InputStream

The input stream

size:int

The number of bytes to read

Returns:byte[]

an array of byte[size] with the contents read
