Method Detail

convert

public Object convert(Object src,

             TypeInfo<Object> dstType)
               throws ConversionException

Description copied from interface: Converter

Converter from SrcType to DstType. Implementation should assume following: * SrcType is assignable from srcType.getRaw() * DstType is assignable from destType.getRaw() * src.getClass().isAssignableFrom(srcType) == true * DstType class is assignable from returned object

Specified by:

convert in interface Converter<Object,Object>

Parameters:

src - source object

srcType - source object type info

dstType - destination object type info

Returns:

destination object

Throws:

ConversionException

convertType

public <I,O> O convertType(I src,
                  TypeInfo<I> srcType,
                  TypeInfo<O> dstType)
              throws ConversionException

Description copied from interface: ConversionService

Convert source value of specified type to value of destination type

Specified by:

convertType in interface ConversionService

converted value of type which can be assigned to dstType

Throws:

ConversionException

converterByType

public <I,O,T extends Converter<I,O>> T converterByType(Class<T> converterType)

Description copied from interface: ConversionService
