PODAM Journal - Added support for recursive hierarchies

Today I was talking with a colleague about Podam and he rightly made me notice that I didn't think of recursive hierarchies, e.g. a parent-child relationship. For instance a Category object might be such a hierarchical domain model object.

So I arrived at home and I added support for recursive hierarchies. Podam now supports the following POJO:

/**
 *
 */
package uk.co.jemos.podam.test.dto;

import java.io.Serializable;

/**
 * POJO to test a recursive hierarchy, like the one between parent and child
 *
 * @author mtedone
 *
 */
public class RecursivePojo implements Serializable {

    private static final long serialVersionUID = 1L;

    // ------------------->> Constants

    // ------------------->> Instance / Static variables

    /** An int field */
    private int intField;

    /** An instance to itself in a hierarchical structure */
    private RecursivePojo parent;   

    // ------------------->> Public methods

    /**
     * No-args constructor
     */
    public RecursivePojo() {
    }

    // ------------------->> Getters / Setters

    /**
     * @return the intField
     */
    public int getIntField() {
        return intField;
    }

    /**
     * @param intField
     *            the intField to set
     */
    public void setIntField(int intField) {
        this.intField = intField;
    }

    /**
     * @return the parent
     */
    public RecursivePojo getParent() {
        return parent;
    }

    /**
     * @param parent
     *            the parent to set
     */
    public void setParent(RecursivePojo parent) {
        this.parent = parent;
    }   

    // ------------------->> equals() / hashcode() / toString()

    /**
     * Constructs a <code>String</code> with all attributes in name = value
     * format.
     *
     * @return a <code>String</code> representation of this object.
     */
    @Override
    public String toString() {
        final String TAB = "    ";

        StringBuilder retValue = new StringBuilder();

        retValue.append("RecursivePojo ( ").append("intField = ")
                .append(intField).append(TAB).append("parent = ")
                .append(parent).append(TAB).append(" )");

        return retValue.toString();
    }

   

}
