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

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.

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.
