# pojo-derivation
[](https://mvnrepository.com/artifact/cc.duduhuo.util/pojo-derivation-annotations)
[](https://github.com/liying2008/pojo-derivation/blob/master/LICENSE)
Combine multiple POJOs to generate a new POJO.
## 1 Setup
+ Kotlin Project
```gradle
apply plugin: 'kotlin-kapt'
dependencies {
compileOnly('cc.duduhuo.util:pojo-derivation-annotations:1.2.0')
kapt('cc.duduhuo.util:pojo-derivation-compiler:1.2.0')
}
```
+ Pure Java Project
```gradle
dependencies {
compileOnly('cc.duduhuo.util:pojo-derivation-annotations:1.2.0')
annotationProcessor('cc.duduhuo.util:pojo-derivation-compiler:1.2.0')
}
```
## 2 Use
You can use the `Derivation` annotation on any class:
```java
@Derivation(
name = "ABC",
sourceTypes = {A.class, B.class, C.class},
constructorTypes = {ConstructorType.NO_ARGS, ConstructorType.ALL_ARGS, ConstructorType.ALL_SOURCE_OBJS}
)
final class ABCCombine {}
```
Then you will get a new class as shown below:
```java
// This file is automatically generated by pojo-derivation (https://github.com/liying2008/pojo-derivation).
// Do not modify this file -- YOUR CHANGES WILL BE ERASED!

public class ABC {
private int a1;
private String a2;
private boolean b1;
private double b2;
private boolean c1;
private char c2;
@NotNull
private String c3;
public ABC() {
}
public ABC(int a1, String a2, boolean b1, double b2, boolean c1, char c2, String c3) {
this.a1 = a1;
this.a2 = a2;
this.b1 = b1;
this.b2 = b2;
this.c1 = c1;
this.c2 = c2;
this.c3 = c3;
}
public ABC(A a, B b, C c) {
this.setA1(a.getA1());
this.setA2(a.getA2());
this.setB1(b.isB1());
this.setB2(b.getB2());
this.setC1(c.getC1());
this.setC2(c.getC2());
this.setC3(c.getC3());
}
public int getA1() {
return a1;
}
public void setA1(int a1) {
this.a1 = a1;
}
public String getA2() {
return a2;
}
public void setA2(String a2) {
this.a2 = a2;
}
public boolean isB1() {
return b1;
}
public void setB1(boolean b1) {
this.b1 = b1;
}
public double getB2() {
return b2;
}
public void setB2(double b2) {
this.b2 = b2;
}
public boolean isC1() {
return c1;
}
public void setC1(boolean c1) {
this.c1 = c1;
}
public char getC2() {
return c2;
}
public void setC2(char c2) {
this.c2 = c2;
}
public String getC3() {
return c3;
}
public void setC3(String c3) {
this.c3 = c3;
}
}
```
