Class SpockitoValueConverter

java.lang.Object

org.tools4j.spockito.SpockitoValueConverter

All Implemented Interfaces:

ValueConverter

public class SpockitoValueConverter
extends Object
implements ValueConverter

Default value converter implementation for Spockito. All supported conversions are defined as a constant in Converters.

Constom value converter implementations may want to extend this class and add additional converters by overriding initConverterFunctions(). Converters for single types can be registered via registerConverterFunction(Class, Function) and the more generic registerConverter(BiPredicate, ValueConverter).

Method Detail

convert

public <T> T convert(Class<T> type,
                     Type genericType,
                     String value)

Description copied from interface: ValueConverter

Converts the given string value into the target type specified by raw and generic type.

Specified by:

convert in interface ValueConverter

Type Parameters:

T - the target type parameter

Parameters:

type - the target type in raw form, for instance int.class, List.class etc.

genericType - the generic target type, same as type for non-generic types; generic type examples are List<String>, Map<String, Integer> etc.

value - the value to convert, may be null

Returns:

the converted value

initConverterFunctions

protected void initConverterFunctions()

Registers converters for individual types via calls to registerConverterFunction(Class, Function) and the more generic registerConverter(BiPredicate, ValueConverter). All converters registered by this method are defined by Converters.

registerConverterFunction

protected <T> void registerConverterFunction(Class<T> type,
                                             Function<? super String,? extends T> converter)

Register a conversion fuction for the specified type. The function is applied for types exactly matching the given type only (but not to supertypes of this type).

Type Parameters:

T - the targe parameter

Parameters:

type - the target type

converter - a function converting from string to target type

registerConverter

protected void registerConverter(BiPredicate<Class<?>,? super Type> applicable,
                                 ValueConverter converter)

Register a value converter for some subgroup of types selected for by the given predicate. The two arguments passed to the applicable predicate are type and generic type of the target value. The predicate returns true if the specified value converter is applicable for such a value.

Value converters registered via this method will be queried in registration order. If two converters are applicable to some value, the first whose predicate returns true will be used.

Parameters:

applicable - a predicate returning true if the specified converter can be applied for a value of the type/generic-type passed to the predicate, and false otherwise

converter - a value converter from string to target type
