Constructor Detail

AbstractBookmarkableMapper

public AbstractBookmarkableMapper()

Construct.

AbstractBookmarkableMapper

public AbstractBookmarkableMapper(String mountPath,
                          IPageParametersEncoder pageParametersEncoder)

Method Detail

parseRequest

protected abstract AbstractBookmarkableMapper.UrlInfo parseRequest(Request request)

Parse the given request to an AbstractBookmarkableMapper.UrlInfo instance.

Parameters:

request -

Returns:

UrlInfo instance or null if this encoder can not handle the request

buildUrl

protected abstract Url buildUrl(AbstractBookmarkableMapper.UrlInfo info)

Builds URL for the given AbstractBookmarkableMapper.UrlInfo instance. The URL this method produces must be parseable by the parseRequest(Request) method.

Parameters:

info -

Returns:

Url result URL

pageMustHaveBeenCreatedBookmarkable

protected abstract boolean pageMustHaveBeenCreatedBookmarkable()

Indicates whether hybrid RenderPageRequestHandler URL for page will be generated only if page has been created with bookmarkable URL.

For generic bookmarkable encoders this method should return true. For explicit (mounted) encoders this method should return false

Returns:

true if hybrid URL requires page created bookmarkable, false otherwise.

getCompatibilityScore

public int getCompatibilityScore(Request request)

processBookmarkable

protected IRequestHandler processBookmarkable(Class<? extends IRequestablePage> pageClass,
                                  PageParameters pageParameters)

Creates a IRequestHandler that processes a bookmarkable request.

Parameters:

pageClass -

pageParameters -

Returns:

a IRequestHandler capable of processing the bookmarkable request.

processHybrid

protected IRequestHandler processHybrid(PageInfo pageInfo,
                            Class<? extends IRequestablePage> pageClass,
                            PageParameters pageParameters,
                            Integer renderCount)

Creates a IRequestHandler that processes a hybrid request. When the page identified by pageInfo was not available, the request should be treated as a bookmarkable request.

Parameters:

pageInfo -

pageClass -

pageParameters -

renderCount -

Returns:

a IRequestHandler capable of processing the hybrid request.

processListener

protected IRequestHandler processListener(PageComponentInfo pageComponentInfo,
                              Class<? extends IRequestablePage> pageClass,
                              PageParameters pageParameters)

Creates a IRequestHandler that processes a listener request.

Parameters:

pageComponentInfo -

pageClass -

pageParameters -

Returns:

a IRequestHandler that invokes the listener interface

mapRequest

public IRequestHandler mapRequest(Request request)

checkPageInstance

protected boolean checkPageInstance(IRequestablePage page)

checkPageClass

protected boolean checkPageClass(Class<? extends IRequestablePage> pageClass)

mapHandler

public Url mapHandler(IRequestHandler requestHandler)

getPageInfo

protected final PageInfo getPageInfo(IPageRequestHandler handler)

getPathSegments

protected List<AbstractBookmarkableMapper.MountPathSegment> getPathSegments(String[] segments)

isFixedSegment

protected boolean isFixedSegment(String segment)

extractPageParameters

protected PageParameters extractPageParameters(Request request,
                                   Url url)

Extracts the PageParameters from URL if there are any

getMatchedSegmentSizes

protected int[] getMatchedSegmentSizes(Url url)

segmentsMatch

protected boolean segmentsMatch(String mountedSegment,
                    String urlSegment)

Decides whether a segment from the mounted path matches with a segment from the requested url. A custom implementation of this class may use more complex logic to handle spelling errors

Parameters:

mountedSegment - the segment from the mounted path

urlSegment - the segment from the request url

Returns:

true if the segments match

isCaseSensitiveMatch

protected boolean isCaseSensitiveMatch()

Returns:

whether the matching of mounted segments against request's url ones should be case sensitive or not

setCaseSensitiveMatch

public AbstractBookmarkableMapper setCaseSensitiveMatch(boolean isCaseSensitive)

Sets whether the matching of mounted segments against request's url ones should be case sensitive or not.

Parameters:

isCaseSensitive - a flag indicating whether the matching of mounted segments against request's url ones should be case sensitive or not

Returns:

this instance, for chaining

setPlaceholders

protected boolean setPlaceholders(PageParameters parameters,
                      Url url)

Replaces mandatory and optional parameters with their values. If a mandatory parameter is not provided then the method returns false indicating that there is a problem. Optional parameters with missing values are just dropped.

Parameters:

parameters - The parameters with the values

url - The url with the placeholders

Returns:

true if all mandatory parameters are properly substituted, false - otherwise

urlStartsWithMountedSegments

protected boolean urlStartsWithMountedSegments(Url url)
