                              String functionClassName)

Description copied from interface: ValangBased

Adds the a new custom function to be used in the valang el.

Specified by:

addCustomFunction in interface ValangBased

Parameters:

functionName - The name of the function.

functionClassName - The fully qualified class name of the function.

getCustomFunctions

public Map getCustomFunctions()

getDateParsers

public Map getDateParsers()

createValangParser

public ValangParser createValangParser(String expression)

Creates a new ValangParser that is already configured with the proper custom functions and date parsers.

Parameters:

expression - Valang language validation expression.

Returns:

A new ValangParser.

createValangParser

public ValangParser createValangParser(String expression,
                                       String className)

Creates a new ValangParser that is already configured with the proper custom functions and date parsers and uses the class name to perform bytecode generation to avoid reflection.

Parameters:

expression - Valang language validation expression.

className - Name of the Class to generated a Function to retrieve a property.

Returns:

A new ValangParser.

initValang

public void initValang(Object object)

getAllCustomFunctions

public Map getAllCustomFunctions()

Returns all the custom functions that can be found. This method returns all the custom functions that were explicitly registered with this instance and all custom functions that can be found in the application context (if one is set) by looking for FunctionDefinition beans.

Returns:

All the custom function that can be found.
