Interface PostResponse

All Known Implementing Classes:

AbstractPostResponse, HtmlResponse, HtmlResponse, JSONResponse

public interface PostResponse

The PostResponse interface defines the API of a response container which can (and should) be used by PostOperation services to prepare responses to be sent back to the client.

This bundle provides a preconfigured HtmlResponse and a JSONResponse implementation of this interface. Clients may extend the AbstractPostResponse class to provide their own response implementations.

Method Detail

setReferer

void setReferer(java.lang.String referer)

Sets the referer property

getReferer

java.lang.String getReferer()

Returns the referer previously set by setReferer(String)

setPath

void setPath(java.lang.String path)

Sets the absolute path of the item upon which the request operated.

getPath

java.lang.String getPath()

Returns the absolute path of the item upon which the request operated.

If the setPath(String) method has not been called yet, this method returns null.

setCreateRequest

void setCreateRequest(boolean isCreateRequest)

Sets whether the request was a create request or not.

isCreateRequest

boolean isCreateRequest()

Returns true if this was a create request.

Before calling the setCreateRequest(boolean) method, this method always returns false.

setLocation

void setLocation(java.lang.String location)

Sets the location of this modification. This is the externalized form of the current path.

Parameters:

location -

getLocation

java.lang.String getLocation()

Returns the location of the modification.

If the setLocation(String) method has not been called yet, this method returns null.

setParentLocation

void setParentLocation(java.lang.String parentLocation)

Sets the parent location of the modification. This is the externalized form of the parent node of the current path.

getParentLocation

java.lang.String getParentLocation()

Returns the parent location of the modification.

If the setParentLocation(String) method has not been called yet, this method returns null.

setTitle

void setTitle(java.lang.String title)

Sets the title of the response message

Sets the response status code properties

Parameters:

getStatusCode

int getStatusCode()

Returns the status code of this instance. If the status code has never been set by calling the setStatus(int, String) method, the status code is determined by checking if there was an error. If there was an error, the response is assumed to be unsuccessful and 500 is returned. If there is no error, the response is assumed to be successful and 200 is returned.
