Method Detail

getInstance

public static TypeConverterRegistry getInstance()

Gets the singleton instance of the TypeConverterRegistry.

Returns:

the singleton instance.

findCompatibleConverter

public TypeConverter<?> findCompatibleConverter(java.lang.reflect.Type type)

Finds a TypeConverter for the given Type, falling back to an assignment-compatible TypeConverter if none exist for the given type. That is, if the given Type does not have a TypeConverter, but another Type which can be assigned to the given Type does have a TypeConverter, then that TypeConverter will be used and registered.

Parameters:

type - the Type to find a TypeConverter for (must not be null).

Returns:

a TypeConverter for the given Type.

Throws:

java.util.UnknownFormatConversionException - if no TypeConverter can be found for the given type.

loadKnownTypeConverters

private void loadKnownTypeConverters(java.util.Collection<PluginType<?>> knownTypes)

registerConverter

private TypeConverter<?> registerConverter(java.lang.reflect.Type conversionType,
                                           TypeConverter<?> converter)

Attempts to register the given converter and returns the effective converter associated with the given type.

Registration will fail if there already exists a converter for the given type and neither the existing, nor the provided converter extends from Comparable.

getTypeConverterSupportedType

private static java.lang.reflect.Type getTypeConverterSupportedType(java.lang.Class<? extends TypeConverter> typeConverterClass)

registerPrimitiveTypes

private void registerPrimitiveTypes()

registerTypeAlias

private void registerTypeAlias(java.lang.reflect.Type knownType,
                               java.lang.reflect.Type aliasType)
