Package io.microsphere.reflect

Class JavaType

java.lang.Object

io.microsphere.reflect.JavaType

All Implemented Interfaces:

java.io.Serializable

public class JavaType
extends java.lang.Object
implements java.io.Serializable

Encapsulates a Java Type(Immutable), providing the features:

• supertype
• interfaces
• generic parameters
• raw type
• the tracing source
• the root source
• cast to the super type or interface

Since:
