Constructor Summary

protected	ConversionServiceAwareConverter() Default constructor, expectes to conversion service to be injected using setConversionService(ConversionService).
protected	ConversionServiceAwareConverter(ConversionService conversionService) Create a converter using given conversion service.

Method Summary

protected ConversionExecutor	converterFor(java.lang.Class sourceClass, java.lang.Class targetClass) Returns a conversion executor capable of converting objects from one class to another.
protected ConversionExecutor	fromStringTo(java.lang.Class targetClass) Returns a conversion executor capable of converting string objects to the specified target class.
protected ConversionExecutor	fromStringToAliased(java.lang.String targetAlias) Returns a conversion executor capable of converting string objects to the target class aliased by the provided alias.
ConversionService	getConversionService() Returns the conversion service used.
protected Expression	parseExpression(java.lang.String expressionString) Helper that parsers the given expression string into an expression, using the installed String->Expression converter.
void	setConversionService(ConversionService conversionService) Set the conversion service this object should be made aware of (as it presumably depends on it).
