Method Details

reset

void reset()

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Element>

Throws:

UncheckedIOException - if the underlying Reader errors during a read

next

public Element next()

Specified by:

next in interface Iterator<Element>

Throws:

UncheckedIOException - if the underlying Reader errors during a read

maybeFindNext

private void maybeFindNext()

remove

public void remove()

Specified by:

remove in interface Iterator<Element>

head

public void head(Node node,
 int depth)

Description copied from interface: NodeVisitor

Callback for when a node is first visited.

The node may be modified (e.g. Node.attr(String), replaced Node.replaceWith(Node)) or removed Node.remove(). If it's instanceOf Element, you may cast it to an Element and access those methods.

Specified by:

head in interface NodeVisitor

Parameters:

node - the node being visited.

depth - the depth of the node, relative to the root node. E.g., the root node has depth 0, and a child node of that will have depth 1.

tail

public void tail(Node node,
 int depth)

Description copied from interface: NodeVisitor

Callback for when a node is last visited, after all of its descendants have been visited.

This method has a default no-op implementation.

Note that neither replacement with Node.replaceWith(Node) nor removal with Node.remove() is supported during tail().

Specified by:

tail in interface NodeVisitor

Parameters:

node - the node being visited.

depth - the depth of the node, relative to the root node. E.g., the root node has depth 0, and a child node of that will have depth 1.
