/**
* The in-memory representation of a Java class. This representation serves as
* the starting point for querying class-related information, a process usually
* called "reflection". There are basically three types of {@code Class}
* instances: those representing real classes and interfaces, those representing
* primitive types, and those representing array classes.
*
* Class instances representing object types (classes or interfaces)
*
* These represent an ordinary class or interface as found in the class
* hierarchy. The name associated with these {@code Class} instances is simply
* the fully qualified class name of the class or interface that it represents.
* In addition to this human-readable name, each class is also associated by a
* so-called signature, which is the letter "L", followed by the
* class name and a semicolon (";"). The signature is what the runtime system
* uses internally for identifying the class (for example in a DEX file).
*
* Classes representing primitive types
*
* These represent the standard Java primitive types and hence share their
* names (for example "int" for the {@code int} primitive type). Although it is
* not possible to create new instances based on these {@code Class} instances,
* they are still useful for providing reflection information, and as the
* component type of array classes. There is one {@code Class} instance for each
* primitive type, and their signatures are:
*
*
* - {@code B} representing the {@code byte} primitive type
* - {@code S} representing the {@code short} primitive type
* - {@code I} representing the {@code int} primitive type
* - {@code J} representing the {@code long} primitive type
* - {@code F} representing the {@code float} primitive type
* - {@code D} representing the {@code double} primitive type
* - {@code C} representing the {@code char} primitive type
* - {@code Z} representing the {@code boolean} primitive type
* - {@code V} representing void function return values
*
*
*
Classes representing array classes
*
* These represent the classes of Java arrays. There is one such {@code Class}
* instance per combination of array leaf component type and arity (number of
* dimensions). In this case, the name associated with the {@code Class}
* consists of one or more left square brackets (one per dimension in the array)
* followed by the signature of the class representing the leaf component type,
* which can be either an object type or a primitive type. The signature of a
* {@code Class} representing an array type is the same as its name. Examples
* of array class signatures are:
*
*
* - {@code [I} representing the {@code int[]} type
* - {@code [Ljava/lang/String;} representing the {@code String[]} type
* - {@code [[[C} representing the {@code char[][][]} type (three dimensions!)
