Method Detail
convertIfNecessary
public <T> T convertIfNecessary(Object value, Class<T> requiredType) throws TypeMismatchException
Description copied from interface:TypeConverterConvert the value to the required type (if necessary from a String).Conversions from String to any type will typically use the
setAsTextmethod of the PropertyEditor class, or a Spring Converter in a ConversionService.- Specified by:
convertIfNecessaryin interfaceTypeConverter- Parameters:
value- the value to convertrequiredType- the type we must convert to (ornullif not known, for example in case of a collection element)- Returns:
- the new value, possibly the result of type conversion
- Throws:
TypeMismatchException- if type conversion failed- See Also:
PropertyEditor.setAsText(String),PropertyEditor.getValue(),ConversionService,Converter

convertIfNecessaryin interfaceTypeConverter- Parameters:
value- the value to convertrequiredType- the type we must convert to (ornullif not known, for example in case of a collection element)methodParam- the method parameter that is the target of the conversion (for analysis of generic types; may benull)- Returns:
- the new value, possibly the result of type conversion
- Throws:
TypeMismatchException- if type conversion failed- See Also:
