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.
