Method Detail

convert

public static <T> T convert(String s,
                            Class<? extends T> clazz,
                            Object defaultValue)

Converts a String to a given class if a TypeConverter is available for that class. Falls back to the provided default value if the conversion is unsuccessful. However, if the default value is also invalid, then null is returned (along with a nasty status log message).

Parameters:

s - the string to convert

clazz - the class to try to convert the string to

defaultValue - the fallback object to use if the conversion is unsuccessful

Returns:

the converted object which may be null if the string is invalid for the given type

Throws:

NullPointerException - if clazz is null

IllegalArgumentException - if no TypeConverter exists for the given class
