JavaEntityGenerator

Python script to generate Java class entities

Example

python ./entity_gen.py --equals --toString --hashCode --get --set --class MyClass --builder "Optional<String>:testVariable" "Integer:id"

Result:

import java.util.Objects;
import com.google.common.base.MoreObjects;
public final class MyClass{
    private Optional<String> testVariable;
    private Integer id;

    public final Optional<String> getTestVariable(){

    }

    public final Integer getId(){
        return id;
    }

    public final void setTestVariable(Optional<String> pTestVariable){
        testVariable = pTestVariable;
    }

    public final void setId(Integer pId){
        id = pId;
    }

    @Override
    public boolean equals(Object object){
        if(object == this){
            return true;
        }
        if(object instanceof MyClass){
            MyClass myclass = (MyClass) object;
            if(Objects.equals(testVariable, myclass.testVariable) && Objects.equals(id, myclass.id)) {
                return true;
            }
        }
        return false;
    }
    @Override
