pojo-derivation

Combine multiple POJOs to generate a new POJO.

1 Setup

Kotlin Project

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

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:

@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:
