- ninja.utils.AbstractContext
-
- All Implemented Interfaces:
Context,Context.Impl
public abstract class AbstractContext extends Object implements Context.Impl
Abstract Context.Impl that implements features that are not reliant on the concrete Context implementation. For example, a concrete implementation may have to provide agetHeader()method, but this class could supply a default implementation ofgetAcceptContentType()since it only needs to fetch a value fromgetHeader(). When adding features to aContextplease think about whether it should be fully or partially implemented here or in the concrete implementation.

Method Detail
-
setRoute
public void setRoute(Route route)
- Specified by:
setRoutein interfaceContext.Impl
-
getRoute
public Route getRoute()
Description copied from interface:ContextGet the route for this context
-
getValidation
public Validation getValidation()
Description copied from interface:ContextGet the validation context- Specified by:
getValidationin interfaceContext- Returns:
- The validation context
-
getFlashCookie
@Deprecated public FlashScope getFlashCookie()
Deprecated.Description copied from interface:ContextDeprecated => please use getFlashScope()- Specified by:
getFlashCookiein interfaceContext- Returns:
- FlashScope of this request.
-
getFlashScope
public FlashScope getFlashScope()
Description copied from interface:ContextReturns the flash cookie. Flash cookies only live for one request. Good uses are error messages to display. Almost everything else is bad use of Flash Cookies. A FlashScope is usually not signed. Don't trust the content.- Specified by:
getFlashScopein interfaceContext- Returns:
- the flash scope of that request.
-
getSessionCookie
@Deprecated public Session getSessionCookie()
Deprecated.Description copied from interface:ContextDeprecated => please use getSession();- Specified by:
getSessionCookiein interfaceContext- Returns:
- the Session of that request / response cycle.
-
getSession
public Session getSession()
Description copied from interface:ContextReturns the client side session. It is a cookie. Therefore you cannot store a lot of information inside the cookie. This is by intention. If you have the feeling that the session cookie is too small for what you want to achieve thing again. Most likely your design is wrong.- Specified by:
getSessionin interfaceContext- Returns:
- the Session of that request / response cycle.
-
getContextPath
public String getContextPath()
Description copied from interface:ContextGet the context path on which the application is running That means: - when running on root the context path is empty - when running on context there is NEVER a trailing slash We conform to the following rules: Returns the portion of the request URI that indicates the context of the request. The context path always comes first in a request URI. The path starts with a "/" character but does not end with a "/" character. For servlets in the default (root) context, this method returns "". The container does not decode this string. As outlined by: http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpServletRequest.html#getContextPath()- Specified by:
getContextPathin interfaceContext- Returns:
- the context-path with a leading "/" or "" if running on root
-
getRequestPath
public String getRequestPath()
Description copied from interface:ContextReturns the path that Ninja should act upon. For instance in servlets you could have soemthing like a context prefix. /myContext/app If your route only defines /app it will work as the requestpath will return only "/app". A context path is not returned. It does NOT decode any parts of the url.

getRequestPathin interfaceContext- Returns:
- The the path as seen by the server. Does exclude any container set context prefixes. Not decoded.
-
getRealRemoteAddr

Get the "real" address of the client connection. Does not take any header (e.g. X-Forwarded-For) into account.- Returns:
- The real address of the client connection
-
getRemoteAddr
public String getRemoteAddr()
Description copied from interface:ContextReturns the Internet Protocol (IP) address of the client or last proxy that sent the request. For HTTP servlets, same as the value of the CGI variableREMOTE_ADDR. To honour the X-Forwarded-For flag make sure you set "ninja.x_forwarded_for_enabled=true" in your application.conf. Default behavior is NOT to take X-Forwarded-For flag into account.- Specified by:
getRemoteAddrin interfaceContext- Returns:
- a
Stringcontaining the IP address of the client that sent the request. Takes into account X-Forwarded-For header if configured to do so.
-
getAttribute
public <T> T getAttribute(String name, Class<T> clazz)
Description copied from interface:ContextGets an attribute value previously set byContext.setAttribute(java.lang.String, java.lang.Object).This is a convenience method, equivalent to:
return clazz.cast(getAttribute(name));Attributes are shared state for the duration of the request; useful to pass values between
filtersand controllers.- Specified by:
getAttributein interfaceContext- Returns:
- the attribute value, or
nullif the attribute does not exist

Description copied from interface:ContextFinalizing the headers copies all stuff into the headers. After finalizing the headers you can access the responseStreams. This method does not set any Ninja session of flash information. Eg. When serving static assets this is the method you may want to use.

finalizeHeadersWithoutFlashAndSessionCookiein interfaceContext
-

(in this order : {@see Result.TEXT_HTML} > {@see Result.APPLICATION_XML} > {@see Result.APPLICATION_JSON} > {@see Result.TEXT_PLAIN} > {@see Result.APPLICATION_OCTET_STREAM} level- or quality-parameter are ignored with this method.) E.g. Accept: text/*;q=0.3, text/html;q=0.7, text/html;level=1,text/html;level=2;q=0.4 The Accept request-header field can be used to specify certain media types which are acceptable for the response.
