Method Detail

validateConfigurationDescription

public static void validateConfigurationDescription(java.lang.Class<?> implementingClass)
                                             throws IllegalConfigurationDescriptionException

Validates the ConfigurationDescription of the given class including its subclasses. This does not include interfaces!

Parameters:

implementingClass - the class implementing a component type (and potentially annotated (or its ancestor classes) with ConfigurationDescription)

Throws:

IllegalConfigurationDescriptionException - if the configuration descriptions contains inherent errors, like a default value that doesn't match the specified type of a property or a ConfigurationValidator that can't be instantiated

validateConfiguration

public static Configuration validateConfiguration(Configuration instConf,
                                                  java.lang.Class<?> implementingClass,
                                                  java.lang.String instanceName)
                                           throws ConfigurationException

Validates the given configuration against the ConfigurationDescription of the given class. If the given class and all of its ancestors are not annotated with ConfigurationDescription this method will just return.

For missing values of configuration entries that are not marked as required their default value will be filled into the configuration. Please note that a property value is not considered missing as long as the default / anonymous instance provides a value for that property.

Parameters:

instConf - the configuration of an instance of the component

implementingClass - the class implementing a component type (and potentially annotated with

instanceName - the instance name is only needed to provide better messages in exceptions

Returns:

The instance configuration to allow for calling this method in a call to a super-constructor.

Throws:

ConfigurationException - if the configuration contained errors

validateConfiguration

public static Configuration validateConfiguration(Configuration instConf,
                                                  java.lang.Class<?> implementingClass,
                                                  boolean includeIfaces,
                                                  java.lang.String instanceName)
                                           throws ConfigurationException

Validates the given configuration against the ConfigurationDescription of the designated class its parent classes and optionally also its (parent) interfaces. If the designated class and all of its ancestors (possibly including interfaces) are not annotated with ConfigurationDescription this method will just return.

For missing values of configuration entries that are not marked as required their default value will be filled into the configuration. Please note that a property value is not considered missing as long as the default / anonymous instance provides a value for that property.

Parameters:

instConf - the configuration of an instance of the component

implementingClass - the class implementing a component type (and potentially annotated with

includeIfaces - Whether to also validate the interfaces (and all parent interfaces) of the designated class.

instanceName - the instance name is only needed to provide better messages in exceptions

Returns:

The instance configuration to allow for calling this method in a call to a super-constructor.

Throws:

ConfigurationException - if the configuration contained errors
