getFullDOM

public OJElement getFullDOM()

Description copied from class: Item

Provide the full DOM tree for this item, wrapped in a theory element.

This code is very similar to getTextualDOM() but fetches everything in one go instead of first getting the metadata element and then only the CMP.

Overrides:

getFullDOM in class Item

Returns:

theory element with item content inside, or null if there is an error.

getTextualDOM

public OJElement getTextualDOM()

Construct the XML DOM tree for the textual content of an exercise.
This method can handle various content formats for exercises.

Overrides:

getTextualDOM in class Item

Returns:

this item in its DOM representation (only metadata and first CMP child) wrapped in a theory element, or null if there is a problem.

isStartable

public boolean isStartable()

isInteractive

public boolean isInteractive()

toString

public String toString()

Overrides:

toString in class Item
