org.araneaframework.http .HttpInputData

All known Subclasses:   org.araneaframework.mock .MockHttpInputData,  org.araneaframework.http.core .StandardServletInputData,
HttpInputData
public interface HttpInputData extends InputData(Code)
Provides methods to deal with the manipulate low-level HTTP constructs. Wraps the HttpServletRequest . The main difference is how we handle the so called PATH_INFO (the additional path after the servlet). The problem is that unlike most common cases Aranea components form a hierarchy. Therefore if a parent is mapped to path prefix "myPath/*" and its child is mapped to a path prefix "myChildPath/*" if the path handling were absolute the child would never get the mapped calles. This is due to the child being really mapped to the path "myPath/myChildPath". Therefore the parent must consume the prefix "myPath/" using method pushPathPrefix() and then the child will be correctly matched to the relative path "myChildPath".

Method Summary
String getCharacterEncoding()
     Returns the character encoding that is used to decode the request parameters.
String getContainerPath()

String getContainerURL()
     Returns an URL pointing to the Aranea container (in most cases the dispatcher servlet).
String getContentType()
     Returns the MIME content type of the request body or null if the body is lacking.
String getContextPath()

String getContextURL()
     Returns an URL pointing to the Aranea container context (in most cases the web application root).
Locale getLocale()
     Returns the preferred Locale that the client will accept content in, based on the Accept-Language header.
Iterator getParameterNames()
     Returns an iterator over names of the parameters submitted with the current request.
String[] getParameterValues(String name)
     Returns the array of values of the particular parameter submitted with the current request.
String getPath()
     Returns the path on the server starting from the dispatcher servlet that has been submitted as the part of the request target URL.
String getRequestURL()
     Returns the target URL of the current request.
void popPathPrefix()
     Restores the previously consumed path prefix.
void pushPathPrefix(String pathPrefix)
     Consumes the path prefix allowing children to be mapped to a relative path.
void setCharacterEncoding(String encoding)
     Sets the character encoding that is used to decode the request parameters.

Method Detail
getCharacterEncoding
String getCharacterEncoding()(Code)
Returns the character encoding that is used to decode the request parameters.

getContainerPath
String getContainerPath()(Code)

since:
   1.1

getContainerURL
String getContainerURL()(Code)
Returns an URL pointing to the Aranea container (in most cases the dispatcher servlet).

getContentType
String getContentType()(Code)
Returns the MIME content type of the request body or null if the body is lacking.

getContextPath
String getContextPath()(Code)

since:
   1.1

getContextURL
String getContextURL()(Code)
Returns an URL pointing to the Aranea container context (in most cases the web application root).

getLocale
Locale getLocale()(Code)
Returns the preferred Locale that the client will accept content in, based on the Accept-Language header. If the client request doesn't provide an Accept-Language header, this method returns the default locale for the server.

getParameterNames
Iterator getParameterNames()(Code)
Returns an iterator over names of the parameters submitted with the current request.

getParameterValues
String[] getParameterValues(String name)(Code)
Returns the array of values of the particular parameter submitted with the current request.

getPath
String getPath()(Code)
Returns the path on the server starting from the dispatcher servlet that has been submitted as the part of the request target URL.

getRequestURL
String getRequestURL()(Code)
Returns the target URL of the current request.

popPathPrefix
void popPathPrefix()(Code)
Restores the previously consumed path prefix.

pushPathPrefix
void pushPathPrefix(String pathPrefix)(Code)
Consumes the path prefix allowing children to be mapped to a relative path.

setCharacterEncoding
void setCharacterEncoding(String encoding)(Code)
Sets the character encoding that is used to decode the request parameters. Note that this must be called before any parameters are read according to the Servlet specification.
