| /** |
| * 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. |
| * |
| * <h4>Class instances representing object types (classes or interfaces)</h4> |
| * <p> |
| * 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 <em>signature</em>, 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). |
| * </p> |
| * <h4>Classes representing primitive types</h4> |
| * <p> |
| * 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: |
| * </p> |
| * <ul> |
| * <li>{@code B} representing the {@code byte} primitive type</li> |
| * <li>{@code S} representing the {@code short} primitive type</li> |
| * <li>{@code I} representing the {@code int} primitive type</li> |
| * <li>{@code J} representing the {@code long} primitive type</li> |
| * <li>{@code F} representing the {@code float} primitive type</li> |
| * <li>{@code D} representing the {@code double} primitive type</li> |
| * <li>{@code C} representing the {@code char} primitive type</li> |
| * <li>{@code Z} representing the {@code boolean} primitive type</li> |
| * <li>{@code V} representing void function return values</li> |
| * </ul> |
| * <p> |
| * <h4>Classes representing array classes</h4> |
| * <p> |
| * 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: |
| * </p> |
| * <ul> |
| * <li>{@code [I} representing the {@code int[]} type</li> |
| * <li>{@code [Ljava/lang/String;} representing the {@code String[]} type</li> |
| * <li>{@code [[[C} representing the {@code char[][][]} type (three dimensions!)</li> |
| * </ul> |
