+/**
+ * @class Ext.form.VTypes
+ * <p>This is a singleton object which contains a set of commonly used field validation functions.
+ * The validations provided are basic and intended to be easily customizable and extended.</p>
+ * <p>To add custom VTypes specify the <code>{@link Ext.form.TextField#vtype vtype}</code> validation
+ * test function, and optionally specify any corresponding error text to display and any keystroke
+ * filtering mask to apply. For example:</p>
+ * <pre><code>
+// custom Vtype for vtype:'time'
+var timeTest = /^([1-9]|1[0-9]):([0-5][0-9])(\s[a|p]m)$/i;
+Ext.apply(Ext.form.VTypes, {
+ // vtype validation function
+ time: function(val, field) {
+ return timeTest.test(val);
+ },
+ // vtype Text property: The error text to display when the validation function returns false
+ timeText: 'Not a valid time. Must be in the format "12:34 PM".',
+ // vtype Mask property: The keystroke filter mask
+ timeMask: /[\d\s:amp]/i
+});
+ * </code></pre>
+ * Another example:
+ * <pre><code>
+// custom Vtype for vtype:'IPAddress'
+Ext.apply(Ext.form.VTypes, {
+ IPAddress: function(v) {
+ return /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/.test(v);
+ },
+ IPAddressText: 'Must be a numeric IP address',
+ IPAddressMask: /[\d\.]/i
+});
+ * </code></pre>
+ * @singleton
