Method Detail

getReflectionUtil

public ReflectionUtil getReflectionUtil()

This method gets the ReflectionUtilImpl instance to use.

Returns:

the ReflectionUtilImpl to use.

setReflectionUtil

@Inject
public void setReflectionUtil(ReflectionUtil reflectionUtil)

Parameters:

reflectionUtil - is the reflectionUtil to set

convert

public final <T extends TARGET> T convert(SOURCE value,
                                          Object valueSource,
                                          Class<T> targetClass)

Description copied from interface: SimpleValueConverter

This method converts the given pojo to the <TARGET>-type.

Specified by:

convert in interface SimpleValueConverter<SOURCE,TARGET>

Type Parameters:

T - is the generic type of targetClass.

Parameters:

value - is the value to convert.

valueSource - describes the source of the value. This may be the filename where the value was read from, an XPath where the value was located in an XML document, etc. It is used in exceptions thrown if something goes wrong. This will help to find the problem easier.

targetClass - is the type to convert the value to.

Returns:

the converted value or null if the conversion is NOT possible. The returned value has to be an instance of the given targetType.
