Package io.microsphere.reflect

Class MemberDefinition<M extends java.lang.reflect.Member>

java.lang.Object

io.microsphere.reflect.ReflectiveDefinition

io.microsphere.reflect.MemberDefinition<M>

Type Parameters:

M - the type of the member, which must be a subclass of Member

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

ExecutableDefinition, FieldDefinition

@Immutable
public abstract class MemberDefinition<M extends java.lang.reflect.Member>
extends ReflectiveDefinition

The definition class for Java Reflection Member.

This abstract class provides a base implementation to define and resolve members (such as fields, methods, or constructors) from a class. It extends the capabilities of the ReflectiveDefinition class by adding support for member names and lazy resolution of the actual reflection object.

Example Usage

{@code
 public class FieldDefinition extends MemberDefinition {

     public FieldDefinition(Version since, String declaredClassName, String name) {
         super(since, null, declaredClassName, name);
     }

Since:

1.0.0
