io microsphere reflect MemberDefinition

MemberDefinition

Type: Class | Module: microsphere-java-core | Package: io.microsphere.reflect | Since: 1.0.0

Source: microsphere-java-core/src/main/java/io/microsphere/reflect/MemberDefinition.java

Overview

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

`public class FieldDefinition extends MemberDefinition {

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

### Declaration

```java
public abstract class MemberDefinition extends ReflectiveDefinition
```
