injectParams

public Object[] injectParams(HttpMethod method,
                    HttpRequest request,
                    HttpResponse res,
                    io.netty.channel.ChannelHandlerContext ctx,
                    Object[] args)

Specified by:

injectParams in interface ParamInjector

extractCookieParam

protected Object extractCookieParam(MethodParam param,
                        HttpRequest request)

extractHeaderParam

protected Object extractHeaderParam(MethodParam param,
                        HttpRequest request)

extractFormParam

protected Object extractFormParam(MethodParam param,
                      HttpRequest request)

extractQueryParam

protected Object extractQueryParam(MethodParam param,
                       HttpRequest request)

extractPathParam

protected Object extractPathParam(MethodParam param,
                      ResourcePath path)

extractNumberParam

protected Object extractNumberParam(MethodParam param,
                        String value)

Given the parameters try to convert the string value to a numeric value of the method class given in the MethodParam. If a number format exception occurs then the param at the given index is set to null. Resource classes should use the boxed class types of numbers if they want to differentiate between 0 and an invalid format. i.e. use Integer,Double,Float,Long,Byte and short instead of int,double etc... if the primitive types are used the values will be 0 if the conversion fails

Parameters:

param - the parameter to be injected

value - the value to be converted
