Method Summary

Modifier and Type	Method	Description
T	convert(F fromObject)	Returns the result of the conversion of the given object.
static <F,T> IConverter<F,T>	create(Object fromType, Object toType, Function<F,T> conversion)	Creates a converter which calls the argument conversion function.
static <F,T> IConverter<F,T>	create(Function<F,T> conversion)	Creates an untyped converter which calls the argument conversion function.
Object	getFromType()	Returns the type whose instances can be converted by this converter.
Object	getToType()	Returns the type to which this converter can convert.

Method Detail

getFromType

Object getFromType()

Returns the type whose instances can be converted by this converter. The return type is Object rather than Class to optionally support richer type systems than the one provided by Java reflection.

Returns:

the type whose instances can be converted, or null if this converter is untyped

getToType

Object getToType()

Returns the type to which this converter can convert. The return type is Object rather than Class to optionally support richer type systems than the one provided by Java reflection.

Returns:

the type to which this converter can convert, or null if this converter is untyped

convert

T convert(F fromObject)

Returns the result of the conversion of the given object.

Parameters:

fromObject - the object to convert, of type getFromType()

Returns:

the converted object, of type getToType()

create

static <F,T> IConverter<F,T> create(Object fromType,
                                                Object toType,
                                                Function<F,T> conversion)

Creates a converter which calls the argument conversion function.

Parameters:

fromType - the from type

toType - the to type

conversion - the conversion function

Returns:

the new converter

Since:

1.6

create

static <F,T> IConverter<F,T> create(Function<F,T> conversion)

Creates an untyped converter which calls the argument conversion function. null is used as the to and from types.

Parameters:

conversion - the conversion function

Returns:

the new converter
