Constructor Detail

AbstractConverter

                            java.lang.Class<? super T> targetClass)

Method Detail

loadConverters

public void loadConverters()

Description copied from interface: ConverterLoader

Create and register converters with the Java object type conversion framework. If the converter extends one of the converter abstract classes, then the converter will register itself when an instance is created. Otherwise, call Converters.registerConverter(Converter) with the Converter instance.

Specified by:

loadConverters in interface ConverterLoader

convert

public T convert(java.lang.Class<? extends T> targetClass,
                 S obj)
          throws ConversionException

Description copied from interface: Converter

Converts obj to T.

Specified by:

convert in interface Converter<S,T>

Parameters:

targetClass - The Class to convert to

obj - The source Object to convert

Returns:

The converted Object

Throws:

ConversionException

canConvert

public boolean canConvert(java.lang.Class<?> sourceClass,
                          java.lang.Class<?> targetClass)

Description copied from interface: Converter

Returns true if this object can convert sourceClass to targetClass.

Implementations can accomodate class hierarchy ranges by converting super classes or interfaces.

Specified by:

canConvert in interface Converter<S,T>

Parameters:

sourceClass - The source Class

targetClass - The target Class

Returns:

true if this object can convert sourceClass to targetClass.

getSourceClass

public java.lang.Class<? super S> getSourceClass()

Description copied from interface: Converter

Returns the source Class for this converter.

Specified by:

getSourceClass in interface Converter<S,T>

Returns:

The source Class for this converter

getTargetClass

public java.lang.Class<? super T> getTargetClass()

Description copied from interface: Converter

Returns the target Class for this converter.

Specified by:

getTargetClass in interface Converter<S,T>

Returns:

The target Class for this converter
