Method Detail

plan2OmdocJDom

public static OJDocument plan2OmdocJDom(List course)

This method is used to generate a OmdocJDom document from a JShop2 plan. The plan contains a list of predicate,which will be handled here to create the OJDocument. In this method, the list of predicate will be read recursively, and for each predicate there's an appropriate 'handler'. Here we just call a strategy methode 'parsePredicate()' to analyse the content of predicate and use the appropriate handler. As the concrete predicates are generated by JShop2, we have to transform the predicates to string.

Parameters:

course -

Returns:

OJDocument doc if the parameter 'course' is not null, null if the course is null

convertToStringList

public static List convertToStringList(List course)

convert the Predicate Objects in the List to Strings for more efficient parsing

Parameters:

course - (List of Predicate

Returns:

new list of Strings

removeEmptySections

public static List removeEmptySections(List course)

Filter the list of String, remove such empty sections. Empty section, which only have start section and endsection but no content.

Parameters:

course -

Returns:

the new list of String

getDocumentString

public static String getDocumentString(OJDocument omdoc)

print out the DOM Object as XML string

Returns:

the output String

getCurrentDate

public static String getCurrentDate()

This method return the current date of the system's computer in following format: "yyyy-MM-dd'T'HH:mm:ss"

Returns:
