Interface HstParameterInfoProxyFactory

public interface HstParameterInfoProxyFactory

HstParameterInfoProxyFactory is a factory interface for creating a proxy for an interface that is referred to by a ParametersInfo annotation. The ParametersInfo annotation is used to annotate HstComponent classes. The interface referred to by the ParametersInfo annotation is returned as proxy by the createParameterInfoProxy(ParametersInfo, ParameterConfiguration, HttpServletRequest, HstParameterValueConverter) method. The getters in the interface that are annotated with the Parameter annotation are delegated through the proxy to the backing ComponentConfiguration

Method Summary

Method Details

createParameterInfoProxy

<T> T createParameterInfoProxy(ParametersInfo parametersInfo,
 ParameterConfiguration parameterConfiguration,
 jakarta.servlet.http.HttpServletRequest request,
 HstParameterValueConverter converter)

Returns a proxy instance of the interface T. The proxy delegates the Parameter annotated getters in the interface T to the backing ComponentConfiguration parameters, thus to ParameterConfiguration.getParameter(String, org.hippoecm.hst.core.request.ResolvedSiteMapItem)

Type Parameters:

T - proxy instance of the interface T

Parameters:

parametersInfo - the ParametersInfo annotation

parameterConfiguration - the backing ParameterConfiguration

request - the HttpServletRequest

converter - the HstParameterValueConverter that does the actual conversion

Returns:

proxy instance of the interface T

Throws:

IllegalArgumentException - if ParametersInfo.type() does not return an interface or when parameterValueConverter is null
