Method Detail

preprocessValue

Object preprocessValue(String value,
                       Class<?> type)
                       throws BeanConfigurationException
Preprocesses the specified bean configuration value. The optional type provided to this method is a hint (not a requirement) for the preprocessor to resolve the value to a compatible value or a (string) value than can be unmarshalled into that type. The preprocessor is not required to perform any type conversion but should rather filter out incompatible values from its result.

Parameters:
value - The configuration value to preprocess, must not be null.
type - The target type of the value, may be null.
Returns:
The processed configuration value or null if none.
Throws:
BeanConfigurationException - If an error occurred while preprocessing the value.
