+ Attributes can be configured to be <code>readOnly</code>, stopping them from being modified by the end user, or <code>writeOnce</code> allowing them to only be set by the end user, but only once. This example demonstrates how to setup attributes for your class as <code>readOnly</code> or <code>writeOnce</code> attributes, and shows how their behavior differs when the end user attempts to set their values.

+
+ <h3>ReadOnly And WriteOnce</h3>
+
+<p>Attribute supports the ability to configure attributes to be <code>readOnly</code> or <code>writeOnce</code>. <code>readOnly</code> attributes cannot be set by the end user, either through initial values passed to the constructor, or by invoking the <code>set</code> method. <code>writeOnce</code> attributes on the other hand, can be set by the user, but only once, either during initialization or through a call to <code>set</code>. Once a value is established for a <code>writeOnce</code> attribute, it cannot be reset to another value by the user.</p>
+
+<h3>Configuring ReadOnly And WriteOnce Attributes</h3>
+
+<p>This example sets up a custom class, <code>MyClass</code>, with two attributes, <code>foo</code> and <code>bar</code>. <code>foo</code> is configured to be a <code>readOnly</code> attribute, and <code>bar</code> is configured to be a <code>writeOnce</code> attribute:</p>
+
+<textarea name="code" class="JScript" rows="1" cols="60">
+ // Setup a custom class with attribute support
+ function MyClass(cfg) {
+ this.addAttrs(Y.merge(MyClass.ATTRIBUTES), cfg);
+ }
+
+ // Setup attribute configuration
+ MyClass.ATTRIBUTES = {
+ "foo" : {
+ value: "Default Foo",
+ readOnly: true
+ },
+
+ "bar" : {
+ value: "Default Bar",
+ writeOnce: true
+ }
+ };
+</textarea>
+
+<h3>Attempting To Set Values</h3>
+
+<p>We first attempt to set values for both attributes in the constructor (used to intialize the attributes) and see that only <code>bar</code>, the <code>writeOnce</code> attribute, gets set to the user provided value:</p>
+
+<textarea name="code" class="JScript" rows="1" cols="60">
+ var o1 = new MyClass({
+ foo: "User Foo",
+ bar: "User Bar"
+ });
+
+ print("Initial Set", "header");
+ print("foo value (readOnly):", "subheader");
+ print(o1.get("foo"));
+
+ print("bar value (writeOnce):", "subheader");
+ print(o1.get("bar"));
+</textarea>
+
+<p>We then attempt to set values for both attributes again, using <code>set</code>, and see that niether of the values are modified:</p>
+
+<textarea name="code" class="JScript" rows="1" cols="60">
+ print("Try Setting Again", "header");
+ o1.set("foo", "User Reset Foo");
+ o1.set("bar", "User Reset Bar");
+
+ print("Final foo value (readOnly)", "subheader");
+ print(o1.get("foo"));
+
+ print("Final bar value (writeOnce)", "subheader");
+ print(o1.get("bar"));
+</textarea>
+
+<h3>Setting The State Of ReadOnly Values Internally</h3>
+
+<p>Although the user cannot update the value of <code>readOnly</code> attributes, it maybe neccessary for the host object to update it's value internally. The example shows how this can be done, using the private <code>_set</code> property on the host:</p>
+
+<textarea name="code" class="JScript" rows="1" cols="60">
+ MyClass.prototype.doSomething = function() {
+ // ... Do something which requires
+ // MyClass to change the value
+ // of foo ...
+
+ // Host code can reset value of
+ // readOnly attributes interally,
+ // by working with the private _set property
+
+ this._set("foo", "New Default Foo");
+ };
+</textarea>
