Method Summary

IActionList	getMergedActions(IObjectTypeHandlerList list)
Collection	getMergedMultiValuedProperties(IObjectTypeHandlerList list, String propertykey)
Properties	getMergedProperties(IObjectTypeHandlerList list)
IObjectTypeHandlerList	rankHandlers(IObjectTypeHandlerList list) The ranking mechanism works after the following schema: For every selection criteria given in an IObjectTypeHandler , the algorithms gives points to this handler if a path is given -> 8 points if a resource type is given -> 4 points if a mimetype is given -> 2 points if an extension is given -> 1 point If several handlers have the same score after that procedure, the length of the resource path acts as the tie breaker: The more folders of the path are specified, the more exact the match naturally becomes.

Method Detail

getMergedActions

public IActionList getMergedActions(IObjectTypeHandlerList list)
                             throws WcmException

Parameters:

list - TBD: Description of the incoming method parameter

Returns:

mergedActions

Throws:

WcmException - Exception raised in failure situation

getMergedProperties

public Properties getMergedProperties(IObjectTypeHandlerList list)
                               throws WcmException

Parameters:

list - TBD: Description of the incoming method parameter

Returns:

mergedProperties

Throws:

WcmException - Exception raised in failure situation

getMergedMultiValuedProperties

public Collection getMergedMultiValuedProperties(IObjectTypeHandlerList list,
                                                 String propertykey)
                                          throws WcmException

Throws:

WcmException

rankHandlers

public IObjectTypeHandlerList rankHandlers(IObjectTypeHandlerList list)
                                    throws WcmException

The ranking mechanism works after the following schema: For every selection criteria given in an IObjectTypeHandler , the algorithms gives points to this handler if a path is given -> 8 points if a resource type is given -> 4 points if a mimetype is given -> 2 points if an extension is given -> 1 point If several handlers have the same score after that procedure, the length of the resource path acts as the tie breaker: The more folders of the path are specified, the more exact the match naturally becomes. If this is still tied, then the OTH-Files are valid for the exact same set of resources. This points to a less-optimal configuration. In this case, the behavior of the method is not determined.

Parameters:

list - a list of matching handlers

Returns:

the list of handlers, ranked by matching: The best matching handler is in first position

Throws:

WcmException - Exception raised in failure situation

writeDebugInformation

public String writeDebugInformation(IResource res,
                                    IObjectTypeHandlerList result)
