    <p>I have a variable arguments defined as Object[][] enable my app to send a series of KEY/VALUE pairs to a function. Below the code handles Strings, Integers and ArrayLists of Strings and Integers. I'd like to extend this to support Doubles and Booleans (and ArrayLists of both).</p> <p>The function has a lot of repetitive code.</p> <p>Update: I am using the GWT framework.</p> <p>Q1. Is this the right approach but in need of a generic class provide easier maintenance? If so how? Q2. Is there a better alternative approach?</p> <pre><code>final static int KEY = 0; final static int VALUE = 1; ... String buildParamaters(Object[][] arguments) { JSONObject parameters = new JSONObject(); for (Object[] arg : arguments) { if (isType(arg[VALUE], "java.util.ArrayList")) { JSONArray array = new JSONArray(); if (isType(arg[VALUE], "java.lang.Integer")) { ArrayList&lt;String&gt; values = (ArrayList&lt;String&gt;) arg[VALUE]; for (int i=0; i&lt;values.size(); i++) { array.set(i, new JSONString(values.get(i))); } } else { ArrayList&lt;Integer&gt; values = (ArrayList&lt;Integer&gt;) arg[VALUE]; for (int i=0; i&lt;values.size(); i++) { array.set(i, new JSONNumber(values.get(i))); } } parameters.put(arg[KEY].toString(), array); } else if (isType(arg[VALUE], "java.lang.Integer")) { parameters.put(arg[KEY].toString(), new JSONNumber(((Integer)arg[VALUE]).doubleValue())); } else { parameters.put(arg[KEY].toString(), new JSONString((String)arg[VALUE])); } } return parameters.toString(); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
