public Map<String,Object> 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:

initValang

public void initValang(Object object)

getAllCustomFunctions

public Map<String,Object> 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.

findAllCustomFunctionsInApplicationContext

protected Map<String,Object> findAllCustomFunctionsInApplicationContext()

Finds all FunctionDefinition and FunctionWrapper beans in the Spring context.
