    • Method Detail

      • setTypeAnnotation

        void setTypeAnnotation​(SchemaType type)
        Set the type annotation on a node. This must only be called when the caller has verified (by validation) that the node is a valid instance of the specified type. The call is ignored if the node is not an element or attribute node.
        Parameters:
        type - the type annotation (possibly including high bits set to indicate the isID, isIDREF, and isNilled properties)

      • insertChildren

        void insertChildren​(NodeInfo[] source,
                    boolean atStart,
                    boolean inherit)
        Insert a sequence of nodes as children of this node.

        This method takes no action unless the target node is a document node or element node. It also takes no action in respect of any supplied nodes that are not elements, text nodes, comments, or processing instructions.

        The supplied nodes will form the new children. Adjacent text nodes will be merged, and zero-length text nodes removed. The supplied nodes may be modified in situ, for example to change their parent property and to add namespace bindings, or they may be copied, at the discretion of the implementation.

        Parameters:
        source - the nodes to be inserted. The implementation determines what implementation classes of node it will accept; all implementations must accept nodes constructed using the Builder supplied by the newBuilder() method on this object. The supplied nodes may be modified in situ, for example to change their parent property and to add namespace bindings, but this depends on the implementation. The argument array may be modified as a result of the call.
        atStart - true if the new nodes are to be inserted before existing children; false if they are to be inserted after existing children
        inherit - true if the inserted nodes are to inherit the namespaces of their new parent; false if such namespaces are to be undeclared
        Throws:
        java.lang.IllegalArgumentException - if the supplied nodes use a node implementation that this implementation does not accept.

      • insertSiblings

        void insertSiblings​(NodeInfo[] source,
                    boolean before,
                    boolean inherit)
        Insert a sequence of nodes as siblings of this node.

        This method takes no action unless the target node is an element, text node, comment, or processing instruction, and one that has a parent node. It also takes no action in respect of any supplied nodes that are not elements, text nodes, comments, or processing instructions.

        The supplied nodes will form new children of this node. Adjacent text nodes will be merged, and zero-length text nodes removed. The supplied nodes may be modified in situ, for example to change their parent property and to add namespace bindings, or they may be copied, at the discretion of the implementation.

        Parameters:
        source - the nodes to be inserted. The implementation determines what implementation classes of node it will accept; all implementations must accept nodes constructed using the Builder supplied by the newBuilder() method on this object. The supplied nodes may be modified in situ, for example to change their parent property and to add namespace bindings, but this depends on the implementation. The argument array may be modified as a result of the call.
        before - true if the new nodes are to be inserted before the target node; false if they are to be inserted after the target node
        inherit - true if the inserted nodes are to inherit the namespaces of their new parent; false if such namespaces are to be undeclared
        Throws:
        java.lang.IllegalArgumentException - if any supplied node is not a text node, element, comment, or processing instruction or if any of the supplied nodes uses a node implementation that this implementation does not accept.

      • setAttributes

        void setAttributes​(AttributeMap attributes)
        Set the attribute list for this (element) node
        Parameters:
        attributes - the new attribute list
        Throws:
        java.lang.UnsupportedOperationException - if this is not an element node

      • removeAttribute

        void removeAttribute​(NodeInfo attribute)
        Remove an attribute from this element node

        If the target node is not an element, or if the supplied node is not an attribute of this element, this method takes no action.

        The attribute object itself becomes unusable; any attempt to use this attribute object, or any other object representing the same node, is likely to result in an exception. Calling the isDeleted() method on the attribute object will return true.

        Parameters:
        attribute - the attribute node to be removed

      • addAttribute

        void addAttribute​(NodeName name,
                  SimpleType attType,
                  java.lang.String value,
                  int properties,
                  boolean inheritNamespaces)
        Add an attribute to this element node.

        If this node is not an element, the method takes no action. If the element already has an attribute with this name, the method throws an exception.

        This method does not perform any namespace fixup. It is the caller's responsibility to ensure that any namespace prefix used in the name of the attribute (or in its value if it has a namespace-sensitive type) is declared on this element.

        Parameters:
        name - the name of the new attribute
        attType - the type annotation of the new attribute
        value - the string value of the new attribute
        properties - properties including IS_ID and IS_IDREF properties
        inheritNamespaces - true if any namespaces added for the new attribute are to be inherited by descendants of the containing element
        Throws:
        java.lang.IllegalStateException - if the element already has an attribute with the given name.

      • removeNamespace

        default void removeNamespace​(java.lang.String prefix)
        Remove a namespace node from this node. The namespaces of its descendant nodes are unaffected. The method has no effect on non-element nodes, nor on elements if there is no in-scope namespace with the required prefix, nor if the element name or one of its attributes uses this namespace prefix
        Parameters:
        prefix - the namespace prefix.

      • addNamespace

        default void addNamespace​(java.lang.String prefix,
                          java.lang.String uri)
        Add a namespace node from this node. The namespaces of its descendant nodes are unaffected. The method has no effect on non-element nodes. If there is an existing namespace using this prefix, the method throws an exception.
        Parameters:
        prefix - the namespace prefix.
        uri - the corresponding namespace URI

      • delete

        void delete()
        Delete this node (that is, detach it from its parent).

        Following this call, calling isDeleted() on the target node or on any of its descendants (or their attributes) will return true, and the node will in all other respects be unusable. The effect of other operations on the node is undefined.

        If the deleted node has preceding and following siblings that are both text nodes, the two text nodes will be joined into a single text node (the identity of this node with respect to the original text nodes is undefined).

      • isDeleted

        boolean isDeleted()
        Test whether this MutableNodeInfo object represents a node that has been deleted. Generally, such a node is unusable, and any attempt to use it will result in an exception being thrown.
        Returns:
        true if this node has been deleted

      • replace

        void replace​(NodeInfo[] replacement,
             boolean inherit)
        Replace this node with a given sequence of nodes. This node is effectively deleted, and the replacement nodes are attached to the parent of this node in its place.

        The supplied nodes will become children of this node's parent. Adjacent text nodes will be merged, and zero-length text nodes removed. The supplied nodes may be modified in situ, for example to change their parent property and to add namespace bindings, or they may be copied, at the discretion of the implementation.

        Parameters:
        replacement - the replacement nodes. If this node is an attribute, the replacements must also be attributes; if this node is not an attribute, the replacements must not be attributes. The implementation determines what implementation classes of node it will accept; all implementations must accept nodes constructed using the Builder supplied by the newBuilder() method on this object. The supplied nodes may be modified in situ, for example to change their parent property and to add namespace bindings, but this depends on the implementation. The argument array may be modified as a result of the call.
        inherit - true if the replacement nodes are to inherit the namespaces of their new parent; false if such namespaces are to be undeclared
        Throws:
        java.lang.IllegalArgumentException - if any of the replacement nodes is of the wrong kind. When replacing a child node, the replacement nodes must all be elements, text, comment, or PI nodes; when replacing an attribute, the replacement nodes must all be attributes.
        java.lang.IllegalStateException - if this node is deleted or if it has no parent node.
        java.lang.IllegalStateException - if two replacement attributes have the same name.

      • replaceStringValue

        void replaceStringValue​(UnicodeString stringValue)
        Replace the string-value of this node. If applied to an element or document node, this causes all existing children to be deleted, and replaced with a new text node whose string value is the value supplied. The caller is responsible for checking that the value is valid, for example that comments do not contain a double hyphen; the implementation is not required to check for such conditions.
        Parameters:
        stringValue - the new string value

      • rename

        void rename​(NodeName newName,
            boolean inherit)
        Rename this node.

        This call has no effect if applied to a nameless node, such as a text node or comment.

        If necessary, a new namespace binding will be added to the target element, or to the element parent of the target attribute

        Parameters:
        newName - the new name for the node
        inherit - true if any new namespace binding is to be inherited by descendants
        Throws:
        java.lang.IllegalArgumentException - if the new name code is not present in the name pool, or if it has a (prefix, uri) pair in which the prefix is the same as that of an existing in-scope namespace binding and the uri is different from that namespace binding.

      • addNamespace

        void addNamespace​(NamespaceBinding binding,
                  boolean inherit)
        Add a namespace binding (that is, a namespace node) to this element. This call has no effect if applied to a node other than an element.
        Parameters:
        binding - The namespace binding representing the (prefix, uri) pair of the namespace binding to be added. If the target element already has a namespace binding with this (prefix, uri) pair, the call has no effect. If the target element currently has a namespace binding with this prefix and a different URI, an exception is raised. The new namespace binding will also be in scope for the subtree rooted at this node (that is, the namespace is implicitly inherited)
        inherit - true if the new namespace binding is to be inherited by children and descendants
        Throws:
        java.lang.IllegalArgumentException - if the namespace code is not present in the namepool, or if the target element already has a namespace binding for this prefix

      • removeTypeAnnotation

        void removeTypeAnnotation()
        Remove type information from this node (and its ancestors, recursively). This method implements the upd:removeType() primitive defined in the XQuery Update specification. (Note: the caller is responsible for updating the set of nodes marked for revalidation)

      • newBuilder

        Builder newBuilder()
        Get a Builder suitable for building nodes that can be attached to this document.
        Returns:
        a new Builder that constructs nodes using the same object model implementation as this one, suitable for attachment to this tree
