= DataDumper =
== 概要 ==
開発中に、無性にオブジェクトをダンプしたくなったことはありませんか？[[BR]]
もしそうなら、このクラスの出番です。

== サンプル ==
{{{
    /**
     * テスト用Bean
     */
    static class TestBean {
        public TestBean() {    }
        public boolean getBoolean() { return true; }
        public int getInt() { return 123; }
        public float getFloat() { return 123.45f; }
        public double getDouble() { return 123.456d; }
        public String getString() { return "abc"; }
        public Object getObject() { return "obj"; }
        public Object getNull() { return null; }
        public boolean [] getBooleanArray() { return new boolean[]{true, false, true}; }
        public int [] getIntArray() { return new int[]{1, 2, 3}; }
        public float [] getFloatArray() { return new float[]{1.11f, 2.22f, 3.33f}; }
        public double [] getDoubleArray() { return new double[]{1.111d, 2.222d, 3.333d}; }
        public String [] getStringArray() { return new String[]{"a","b","c"}; }
        public Object [] getObjectArray() { return new Object[]{new Boolean(true), new Integer(1),"abc"}; }
        public List getList() { return getLzList().list(); }
        public Map getMap() { return getLzMap().map(); }
        public LzList getLzList() { return new LzList(new String[]{"a","b","c"}); }
        public LzMap getLzMap() { return new LzMap(new String[]{"a","1","b","2","c","3"}); }
        public void setFoo() { assertTrue(false); } //呼ばれない
        public void getBar(int a) { assertTrue(false); } //呼ばれない
    }

    public void testDumpBean() throws Exception {
        DataDumper.dumpBean(System.out, new TestBean());
    }
}}}

結果は以下の通りです。
