Class TypeConverter

java.lang.Object

com.helger.commons.typeconvert.TypeConverter

@Immutable
public final class TypeConverter
extends Object

Helper class for converting base types likes "boolean" to object types like "Boolean".
Uses TypeConverterRegistry.getFuzzyConverter(Class, Class) for retrieving a registered converter. If no converter is found, it is checked whether a mapping from a primitive type to an object type exists.
