Method Detail

setContextParameters

public void setContextParameters(java.util.Map map)

This method sets the context/arguments the listener should operate with. Could be debuglevels and stuff like that.

Specified by:

setContextParameters in interface NotificationListener

getSystemNotificationMessages

public static java.util.List getSystemNotificationMessages()

clearSystemNotificationMessages

public static void clearSystemNotificationMessages()

notify

public void notify(NotificationMessage notificationMessage)

This method gets called when a new NotificationMessage is available. The writer just calls the transactionHistoryController which stores it.

Specified by:

notify in interface NotificationListener

updateRemoteCaches

public void updateRemoteCaches(NotificationMessage notificationMessage)
                        throws java.lang.Exception

This method serializes the notificationMessage and calls the remote actions. As a content-tool can have several preview instances we iterate through the instances that have been indexed in the propertyfile starting with 0.

Throws:

java.lang.Exception

decodeHTTPEncodedString

public java.lang.String decodeHTTPEncodedString(java.lang.String encoded)

As the name indicates, this method takes a URL-encoded string and converts it to a normal javastring. That is, all Mime-encoding is removed.

Parameters:

encoded - The encoded string.

Returns:

An decoded string.

httpEncodedStringToHashtable

public java.util.Hashtable httpEncodedStringToHashtable(java.lang.String encodedstrang)

Converts a serialized hashtable in the url-encoded format to a Hashtable that one can use within the program. A good technique when exchanging information between different applications.

Parameters:

encodedstrang - The url-encoded string.

Returns:

A Hashtable.
