Converts an input value to a target type.

Type Parameters:

T - The target type.

Parameters:

value - The value to convert.

targetType - The type to which to convert.

instance - The object instance whose property value is to be set (necessary when the target type is a component and the value is the component name or id).

Returns:

The converted value.

convertToJS

public static String convertToJS(String snippet)

Process a Javascript code snippet. If the snippet does not have a function wrapper, a no-argument wrapper will be added.

Parameters:

snippet - JS code snippet.

Returns:

A JavaScriptValue object or null if the input was null.

toOptionMaps

public static List<OptionMap> toOptionMaps(Collection<? extends OptionMap.IOptionMapConverter> items)

Converts a collection of IOptionMapConverter items to a list of maps.

Parameters:

items - IOptionMapConverter items to convert.

Returns:

List of converted items.

invokeMethod

public static Object invokeMethod(Object instance,
                                  Method method,
                                  Object... args)

Invokes a method with the provided value(s), performing type conversion as necessary.

Parameters:

instance - Instance that is the target of the invocation (may be null for static methods).

method - The method to invoke.

args - Arguments to be passed to method (may be null if no arguments). Argument values will be coerced to the expected type if possible.

Returns:
