WikiTextParentNode

protected WikiTextParentNode(List<WikiTextNode> children)

Constructs the node

Parameters:

children - The child nodes

Method Details

getCategories

public Set<String> getCategories()

Description copied from interface: WikiTextElement

Category links are leaf nodes but we want to include them as attributes of an article. This gives us three cases to consider:

1. Leaf nodes that are category links. We want to pass these up to the parent nodes. This is handled in Category objects.
2. Other leaf nodes. These aren't categories and should return nothing. This is the default case in the WikiTextNode interface.
3. Parent nodes. These aren't categories by themselves, and should return the union of the categories of their children. This is handled in WikiTextParent nodes

Returns:

A set of categories as strings.

getFieldValuesFromChildren

public static Set<String> getFieldValuesFromChildren(List<WikiTextNode> children,
 Function<? super WikiTextNode,Set<String>> getter)

There is data that flow up to the root from leaf nodes. In this case we can think of it as the union of the child node data.

Parameters:

children - The child elements to get data from.

getter - The function that gets the data

Returns:

All data from the child elements.

rebuildWithContext

public WikiTextNode rebuildWithContext(TreeConstructionContext context)
