Method Summary

Methods
Modifier and Type	Method and Description
`void`	`addErrorMessageVariable(java.lang.String name, java.lang.String value)` Adds a variable to the context used when building error messages for this Validator.
`ErrorMessage`	`evaluateErrorMessage(ErrorMessage error)` Returns the evaluated form of the passed in error message, applying any error message variables that have been assigned to this validator.
`java.lang.String`	`getErrorMessage()` Returns the error message
`java.util.Map`	`getErrorMessageVariables()` Retrieves the current map of error message variables for this Validator
`java.lang.String`	`getLanguage()` Returns language property, which is script language of serverCondition expression that will be executed by the server.
`java.util.List`	`getListProperty(java.lang.String property)` Returns the value of the specified attribute as a List.
`java.util.Map`	`getMapProperty(java.lang.String property)` Returns the value of the specified attribute as a Map.
`java.lang.Object`	`getObjectProperty(java.lang.String property)` Returns the value of the specified element(s) as an Object. Custom XML is transformed to Strings or Java collections by the following rules: Elements with just text (no child elements or attributes) become Strings Elements with child elements or attributes become Maps containing data derived from their subelements Repeating elements (more than one of the same name at the same level) become Lists Sample XML: Map `<validator> <mapCustomProperty key1="value1" key2="value2" /> </validator>` List of String `<validator> <listCustomProperty>ListElement1</listCustomProperty> <listCustomProperty>ListElement2</listCustomProperty> </validator>` List of Map `<validator> <mapCustomProperty key1="value1" key2="value2" /> <mapCustomProperty key1="value1" key2="value2" /> </validator>`
`java.lang.String`	`getProperty(java.lang.String property)` Returns the value of the specified attribute as a string.
`java.lang.Object`	`getScriptImports()` Returns script imports, which are used by script defined in serverCondition expression that will be executed by the server.
`java.lang.String`	`getServerCondition()` Returns the server condition, which is an expression that will be executed by the server.
`java.lang.String`	`getType()` Returns the Validator type
`boolean`	`isClientOnly()` Returns whether this Validator is intended to run only on the client
`boolean`	`isServerOnly()` Returns whether this Validator is intended to run only on the server
`boolean`	`isStopIfFalse()` Returns true if validation should stop if this Validator fails.

```
public java.lang.String getProperty(java.lang.String property)
```
    Returns the value of the specified attribute as a string.
    
    Parameters:
    property - the name of the attribute
    
    Returns:

  - getObjectProperty
```
public java.lang.Object getObjectProperty(java.lang.String property)
```
    Returns the value of the specified element(s) as an Object.
    Custom XML is transformed to Strings or Java collections by the following rules:
  - Elements with just text (no child elements or attributes) become Strings
  - Elements with child elements or attributes become Maps containing data derived from their subelements
  - Repeating elements (more than one of the same name at the same level) become Lists
    Sample XML:
  - Map
    <validator> <mapCustomProperty key1="value1" key2="value2" /> </validator>
  - List of String
    <validator> <listCustomProperty>ListElement1</listCustomProperty> <listCustomProperty>ListElement2</listCustomProperty> </validator>
  - List of Map
    <validator> <mapCustomProperty key1="value1" key2="value2" /> <mapCustomProperty key1="value1" key2="value2" /> </validator>

Parameters:: property - the name of the element(s)
Returns:: the value of the specified element(s) as an Object
