Object

Object\ClassLoader

A simple PSR-4 autoloader that loads files with required classes using namespaces.

In this example, classLoader will try to find each file with a fully-qualified class name starting with the prefix MyNamespace in the /src/myApp directory: \MyNamespace\Class should be found as /src/myApp/Class.php.

If the file cannot not be found, or if it does not have MyNamespace prefix, the classloader will try to find a file by the fully-qualified class name in /src/other directory: \MyNamespace\Class should be found as /src/other/MyNamespace/Class.php.

Object\Byte

This class wraps an integer value and represents it as a binary byte.

Byte of any value and its specified binary unit:
