Method Detail

enhanceConfiguration

public <T> Class<? extends T> enhanceConfiguration(Class<T> configurationClass)

Description copied from interface: ConfigurationEnhancer

Return an enhanced version of the given configuration instance and class.

This interface allows implementations to choose different strategies for enhancement. One option would be directly enhancing the bytecode of configurationClass while another would be to subclass it, CGLib-style. Note that depending on the underlying implementation, certain restrictions may be placed on the class definition. e.g.: a CGLib implementation would disallow final classes/methods, etc.

Specified by:

enhanceConfiguration in interface ConfigurationEnhancer

Parameters:

configurationClass - configuration class - mandatory

Returns:

the enhanced class

validateSuitabilityForEnhancement

public static void validateSuitabilityForEnhancement(Class<?> configurationClass)

Ensures class is suitable for later enhancement, throws an exception otherwise.

Parameters:

candidateConfigurationClass - class to validate

Throws:

IllegalArgumentException - if configurationClass is declared final
