acceptChild

protected boolean acceptChild(@Nullable
 @Nullable String id,
 @NotNull
 @NotNull SVGNode node)

Description copied from class: BaseContainerNode

Determine whether the container accepts this SVGNode as a child. By default, this will always report true but subclasses may choose to reject certain types of nodes.

Overrides:

acceptChild in class BaseContainerNode<TextSegment>

Parameters:

id - the id of the node

node - the node itself

Returns:

whether the node can be inserted as a child.

doAdd

Specified by:

doAdd in class BaseContainerNode<TextSegment>

addContent

public final void addContent(char[] content)

Specified by:

children

public List<? extends @NotNull TextSegment> children()

Description copied from interface: Container

Return all children of this container. Note that the return type of this function internationally contains a wild card to make it a compilation error trying to modify it.

Specified by:

children in interface Container<TextSegment>

Returns:

the list of children.
