Preprocesses a value from a bean configuration before the bean configurator unmarshals it into a bean property. A common use case for such preprocessing is the evaluation of variables within the configuration value.

Benjamin Bentmann

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.

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