/**
  * @class Ext.form.TextField
  * @extends Ext.form.Field
  * 
Basic text field.  Can be used as a direct replacement for traditional text inputs,
  * or as the base class for more sophisticated input controls (like {@link Ext.form.TextArea}
  * and {@link Ext.form.ComboBox}).

  * 
Validation

- * 
Field validation is processed in a particular order.  If validation fails at any particular
- * step the validation routine halts.

+ * 
The validation procedure is described in the documentation for {@link #validateValue}.

+ * 
Alter Validation Behavior

+ * 
Validation behavior for each field can be configured:

  * 
    
- * 
  • 1. Field specific validator
- * 
    
- * 
    If a field is configured with a {@link Ext.form.TextField#validator validator} function,
- * it will be passed the current field value.  The {@link Ext.form.TextField#validator validator}
- * function is expected to return boolean true if the value is valid or return a string to
- * represent the invalid message if invalid.
    
- * 
    • 
- * 
  • 2. Built in Validation
- * 
    
- * 
    Basic validation is affected with the following configuration properties:
    
- * 
    - * Validation    Invalid Message
- * {@link Ext.form.TextField#allowBlank allowBlank}    {@link Ext.form.TextField#emptyText emptyText}
- * {@link Ext.form.TextField#minLength minLength}     {@link Ext.form.TextField#minLengthText minLengthText}
- * {@link Ext.form.TextField#maxLength maxLength}     {@link Ext.form.TextField#maxLengthText maxLengthText}
- * 
    
- * 
    • 
- * 
  • 3. Preconfigured Validation Types (VTypes)
- * 
    
- * 
    Using VTypes offers a convenient way to reuse validation. If a field is configured with a
- * {@link Ext.form.TextField#vtype vtype}, the corresponding {@link Ext.form.VTypes VTypes}
- * validation function will be used for validation.  If invalid, either the field's
- * {@link Ext.form.TextField#vtypeText vtypeText} or the VTypes vtype Text property will be
- * used for the invalid message.  Keystrokes on the field will be filtered according to the VTypes
- * vtype Mask property.
    
- * 
    • 
- * 
  • 4. Field specific regex test
- * 
    
- * 
    Each field may also specify a {@link Ext.form.TextField#regex regex} test.
- * The invalid message for this test is configured with
- * {@link Ext.form.TextField#regexText regexText}.
    
- * 
    • 
- * 
  • Alter Validation Behavior
- * 
    
- * 
    Validation behavior for each field can be configured:
      
  * 
    • {@link Ext.form.TextField#invalidText invalidText} : the default validation message to
  * show if any validation step above does not provide a message when invalid
      • 
  * 
    • {@link Ext.form.TextField#maskRe maskRe} : filter out keystrokes before any validation occurs

Validates a value according to the field's validation rules and returns an array of errors

+     * 
    
+     * 
+     * 
  • 1. Field specific validator
+     * 
    
+     * 
    A validator offers a way to customize and reuse a validation specification.
+     * If a field is configured with a {@link #validator}
+     * function, it will be passed the current field value.  The {@link #validator}
+     * function is expected to return either:
+     *

    • a String to represent the invalid message if invalid (validation halts).

+     *

+     * 
+     * 
  • 2. Basic Validation
+     * 
    
+     *

+     * basic validation proceeds as follows:
    
+     * 
+     * 
      
+     * 
+     * 
    • {@link #allowBlank} : (Invalid message =
+     * {@link #emptyText})
      
+     * Depending on the configuration of {@link #allowBlank}, a
+     * blank field will cause validation to halt at this step and return
+     * Boolean true or false accordingly.  
+     * 
      • 
+     * 
+     * 
    • {@link #minLength} : (Invalid message =
+     * {@link #minLengthText})
      
+     * If the passed value does not satisfy the {@link #minLength}
+     * specified, validation halts.
+     * 
      • 
+     * 
+     * 
    • {@link #maxLength} : (Invalid message =
+     * {@link #maxLengthText})
      
+     * If the passed value does not satisfy the {@link #maxLength}
+     * specified, validation halts.
+     *

+     * 
+     * 
    
+     * 
    • 
+     * 
+     * 
  • 3. Preconfigured Validation Types (VTypes)
+     * 
    
+     * 
    If none of the prior validation steps halts validation, a field
+     * configured with a {@link #vtype} will utilize the
+     * corresponding {@link Ext.form.VTypes VTypes} validation function.
+     * If invalid, either the field's {@link #vtypeText} or
+     * the VTypes vtype Text property will be used for the invalid message.
+     * Keystrokes on the field will be filtered according to the VTypes
+     * vtype Mask property.
    
+     * 
    • 
+     * 
+     * 
  • 4. Field specific regex test
+     * 
    
+     * 
    If none of the prior validation steps halts validation, a field's
+     * configured {@link #regex} test will be processed.
