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, ComponentConfiguration, HstRequest, 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

Modifier and Type	Method and Description
<T> T	createParameterInfoProxy(org.hippoecm.hst.core.parameters.ParametersInfo parametersInfo, ParameterConfiguration parameterConfiguration, javax.servlet.http.HttpServletRequest request, HstParameterValueConverter converter) Returns a proxy instance of the interface T.

Method Detail

createParameterInfoProxy

<T> T createParameterInfoProxy(org.hippoecm.hst.core.parameters.ParametersInfo parametersInfo,
                               ParameterConfiguration parameterConfiguration,
                               javax.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
