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.

Author(s):
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.

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.
