Method Summary

static DispatcherType	getDispatcherType(javax.servlet.http.HttpServletRequest request) Returns the dispatcher type of the request, the dispatcher type is defined to be identical to the semantics of filter mappings in web.xml.

initParametersToMap

public static java.util.LinkedHashMap<java.lang.String,java.lang.String> initParametersToMap(javax.servlet.ServletConfig config)

Returns the init parameters for a ServletConfig object as a Map, preserving the order in which they are exposed by the ServletConfig object.

initParametersToMap

public static java.util.LinkedHashMap<java.lang.String,java.lang.String> initParametersToMap(javax.servlet.FilterConfig config)

Returns the init parameters for a FilterConfig object as a Map, preserving the order in which they are exposed by the FilterConfig object.

getWrappedRequest

public static <T extends javax.servlet.ServletRequest> T getWrappedRequest(javax.servlet.ServletRequest request,
                                                                           java.lang.Class<T> clazz)

Finds a request wrapper object inside the chain of request wrappers.

isMultipart

public static boolean isMultipart(javax.servlet.http.HttpServletRequest request)

Returns true if the request has a content type that indicates that is a multipart request.

isForward

public static boolean isForward(javax.servlet.http.HttpServletRequest request)

Returns true if the request is currently processing a forward operation. This method will return false after an include operation has begun and will return true after that include operations has completed.

isInclude

public static boolean isInclude(javax.servlet.http.HttpServletRequest request)

Returns true if the request is currently processing an include operation.

isError

public static boolean isError(javax.servlet.http.HttpServletRequest request)

Returns true if the request is rendering an error page, either due to a call to sendError() or an exception being thrown in a filter or a servlet that reached the container. Will return true also after an include() or forward() while rendering the error page.

getDispatcherType

public static DispatcherType getDispatcherType(javax.servlet.http.HttpServletRequest request)

Returns the dispatcher type of the request, the dispatcher type is defined to be identical to the semantics of filter mappings in web.xml.
