Method Detail

checkIfNodeIsAssessable

public static boolean checkIfNodeIsAssessable(CourseNode node)

check the given node for assessability.

Parameters:

node -

Returns:

checkForAssessableNodes

public static boolean checkForAssessableNodes(CourseNode node)

Checks recursivley a course structure or a part of it for assessable nodes or for structure course nodes (subtype of assessable node), which 'hasPassedConfigured' or 'hasScoreConfigured' is true. If founds the first node that meets the criterias, it returns true.

Parameters:

node -

Returns:

boolean

getAssessableNodes

public static java.util.List<CourseNode> getAssessableNodes(CourseEditorTreeModel editorModel,
                                                            CourseNode excludeNode)

Get all assessable nodes including the root node (if assessable)

Parameters:

editorModel -

excludeNode - Node that should be excluded in the list, e.g. the current node or null if all assessable nodes should be used

Returns:

List of assessable course nodes

getRoundedScore

public static java.lang.String getRoundedScore(java.lang.Float score)

Parameters:

score - The score to be rounded

Returns:

The rounded score for GUI presentation

isResultVisible

public static boolean isResultVisible(ModuleConfiguration modConfig)

Evaluates if the results are visble or not in respect of the configured CONFIG_KEY_DATE_DEPENDENT_RESULTS parameter.
The results are always visible if no date dependent, or if date dependent only in the period: startDate-endDate. EndDate could be null, that is there is no restriction for the end date.
