instance

public static NodeFactory instance()

createAttribute

public abstract Attribute createAttribute(String name,
                                          String value)

createElementNode

public abstract Node createElementNode(String tagName)

createElementNode

public abstract Node createElementNode(String tagName,
                                       List<? extends Node> children)

createElementNode

public abstract Node createElementNode(String tagName,
                                       List<? extends Node> children,
                                       List<Attribute> attrs)

createElementNode

public abstract Node createElementNode(String tagName,
                                       Node[] children)

createElementNode

public abstract Node createElementNode(String tagName,
                                       Node[] children,
                                       Attribute[] attrs)

createElementNode

public abstract Node createElementNode(String tagName,
                                       Node child)

createCharDataNode

public abstract Node createCharDataNode(String data)

replaceChild

public abstract Node replaceChild(Node node,
                                  int index,
                                  Node child)

The method is used for replacing a child of an element node. The replacement is done by constructing and returning a new element node, which only differs from the original element node in the replaced child.

Parameters:

node - element node.

index - index of the child to replace.

child - new child node.

Returns:

new element node.

insertChild

public abstract Node insertChild(Node n,
                                 int index,
                                 Node child)

The method is used for adding a child to an element node. This is done by constructing and returning a new element node, which only differs from the original element node in the added child.

Parameters:

n - element node.

index - index at which new child is inserted.

child - new child node.

Returns:

new element node.

removeChild

public abstract Node removeChild(Node n,
                                 int index)

The method is used for removing a child from an element node. This is done by constructing and returning a new element node, which only differs from the original element node in the removed child.

Parameters:

n - element node.

index - index specifying the child to remove

Returns:

new element node.
