Constructor Detail

WrappedInstance

public WrappedInstance(T instance,
                       Map<String,PropertyType.PropertyMethod> propertyMethods,
                       Set<Method> validationMethods)

Method Detail

satisfyInterfaces

public void satisfyInterfaces(javax.servlet.ServletContext ctx,
                              javax.servlet.http.HttpServletRequest req)
                       throws WrappedInstance.ResourceUnavailableException

The loader calls this as soon as the instance is created. If the loader did not have access to a request object, then req will be null. If the instance expects request models, an exception will be thrown.

Throws:

WrappedInstance.ResourceUnavailableException

checkCardinality

public void checkCardinality(Set<PropertyType.PropertyStatement> propertyStatements)
                      throws WrappedInstance.CardinalityException

The loader provides the distilled property statements from the RDF. Check that they satisfy the cardinality requested on their methods.

Throws:

WrappedInstance.CardinalityException

setProperties

public void setProperties(ConfigurationBeanLoader loader,
                          Collection<PropertyType.PropertyStatement> propertyStatements)
                   throws PropertyType.PropertyTypeException,
                          ConfigurationBeanLoaderException

The loader provides the distilled property statements from the RDF, to populate the instance.

Throws:

PropertyType.PropertyTypeException

ConfigurationBeanLoaderException

validate

public void validate()
              throws WrappedInstance.ValidationFailedException

After the interfaces have been satisfied and the instance has been populated, call any validation methods to see whether the instance is viable.

Throws:

WrappedInstance.ValidationFailedException

getInstance

public T getInstance()

Once satisfied, populated, and validated, the instance is ready to go.
