Class InnerNodeImpl

  • All Implemented Interfaces:
    Node
    Direct Known Subclasses:
    DocumentFragmentImpl, DocumentImpl, ElementImpl
    public abstract class InnerNodeImpl
extends LeafNodeImpl
    Provides a straightforward implementation of the corresponding W3C DOM interface. The class is used internally only, thus only notable members that are not in the original interface are documented (the W3C docs are quite extensive).

    Some of the fields may have package visibility, so other classes belonging to the DOM implementation can easily access them while maintaining the DOM tree structure.

    This class represents a Node that has a parent Node as well as (potentially) a number of children.

    Some code was adapted from Apache Xerces.

      • appendChild

        public Node appendChild​(Node newChild)
                 throws DOMException
        Description copied from interface: Node
        Adds the node newChild to the end of the list of children of this node. If the newChild is already in the tree, it is first removed.
        Specified by:
        appendChild in interface Node
        Overrides:
        appendChild in class NodeImpl
        Parameters:
        newChild - The node to add.If it is a DocumentFragment object, the entire contents of the document fragment are moved into the child list of this node
        Returns:
        The node added.
        Throws:
        DOMException - HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to append is one of this node's ancestors or this node itself, or if this node is of type Document and the DOM application attempts to append a second DocumentType or Element node.
        WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
        NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly or if the previous parent of the node being inserted is readonly.
        NOT_SUPPORTED_ERR: if the newChild node is a child of the Document node, this exception might be raised if the DOM implementation doesn't support the removal of the DocumentType child or Element child.

      • getChildNodes

        public NodeList getChildNodes()
        Description copied from interface: Node

        getFirstChild in class NodeImpl

      • getLastChild

      • insertBefore

        public Node insertBefore​(Node newChild,
                         Node refChild)
                  throws DOMException
        Description copied from interface: Node
        Inserts the node newChild before the existing child node refChild. If refChild is null, insert newChild at the end of the list of children.
        If newChild is a DocumentFragment object, all of its children are inserted, in the same order, before refChild. If the newChild is already in the tree, it is first removed.

        Note: Inserting a node before itself is implementation dependent.

        Specified by:

        Overrides:
        insertBefore in class NodeImpl
        Parameters:

        refChild - The reference node, i.e., the node before which the new node must be inserted.
        Returns:
        The node being inserted.
        Throws:
        DOMException - HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to insert is one of this node's ancestors or this node itself, or if this node is of type Document and the DOM application attempts to insert a second DocumentType or Element node.
        WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
        NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly or if the parent of the node being inserted is readonly.
        NOT_FOUND_ERR: Raised if refChild is not a child of this node.
        NOT_SUPPORTED_ERR: if this node is of type Document, this exception might be raised if the DOM implementation doesn't support the insertion of a DocumentType or Element node.

      • replaceChild

        public Node replaceChild​(Node newChild,
                         Node oldChild)

        WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
        NO_MODIFICATION_ALLOWED_ERR: Raised if this node or the parent of the new node is readonly.

        NOT_SUPPORTED_ERR: if this node is of type Document, this exception might be raised if the DOM implementation doesn't support the replacement of the DocumentType child or Element child.

      • getTextContent

        public String getTextContent()
                      throws DOMException
        Description copied from interface: Node
        This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. On setting, any possible children this node may have are removed and, if it the new string is not empty or null, replaced by a single Text node containing the string this attribute is set to.
        On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed and the returned string does not contain the white spaces in element content (see the attribute Text.isElementContentWhitespace). Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
        The string returned is made of the text content of this node depending on its type, as defined below:
        Node type Content
        ELEMENT_NODE, ATTRIBUTE_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE concatenation of the textContent attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes. This is the empty string if the node has no children.
        TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODE nodeValue
        DOCUMENT_NODE, DOCUMENT_TYPE_NODE, NOTATION_NODE null
        Specified by:
        getTextContent in interface Node
        Overrides:
        getTextContent in class NodeImpl
        Throws:
        DOMException - DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.
