DeferredAttrImpl

Class Overview

Attribute represents an XML-style attribute of an Element. Typically, the allowable values are controlled by its declaration in the Document Type Definition (DTD) governing this kind of document.

If the attribute has not been explicitly assigned a value, but has been declared in the DTD, it will exist and have that default. Only if neither the document nor the DTD specifies a value will the Attribute really be considered absent and have no value; in that case, querying the attribute will return null.

Attributes may have multiple children that contain their data. (XML allows attributes to contain entity references, and tokenized attribute types such as NMTOKENS may have a child for each token.) For convenience, the Attribute object's getValue() method returns the string version of the attribute's value.

Attributes are not children of the Elements they belong to, in the usual sense, and have no valid Parent reference. However, the spec says they _do_ belong to a specific Element, and an INUSE exception is to be thrown if the user attempts to explicitly share them between elements.

Note that Elements do not permit attributes to appear to be shared (see the INUSE exception), so this object's mutability is officially not an issue.

DeferredAttrImpl inherits from AttrImpl which does not support Namespaces. DeferredAttrNSImpl, which inherits from AttrNSImpl, does.

[Expand] Inherited Methods
From class org.apache.xerces.dom.AttrImpl Node cloneNode(boolean deep) Returns a duplicate of a given node. NodeList getChildNodes() Obtain a NodeList enumerating all children of this node. Element getElement() This method is deprecated. Previous working draft of DOM Level 2. New method is getOwnerElement(). Node getFirstChild() The first child of this Node, or null if none. Node getLastChild() The last child of this Node, or null if none. int getLength() NodeList method: Count the immediate children of this node String getName() In Attributes, NodeName is considered a synonym for the attribute's Name String getNodeName() Returns the attribute name short getNodeType() A short integer indicating what type of node this is. String getNodeValue() In Attribute objects, NodeValue is considered a synonym for Value. Element getOwnerElement() Returns the element node that this attribute is associated with, or null if the attribute has not been added to an element. TypeInfo getSchemaTypeInfo() Method getSchemaTypeInfo. boolean getSpecified() The "specified" flag is true if and only if this attribute's value was explicitly specified in the original document. String getTypeName() String getTypeNamespace() String getValue() The "string value" of an Attribute is its text representation, which in turn is a concatenation of the string values of its children. boolean hasChildNodes() Test whether this node has any children. Node insertBefore(Node newChild, Node refChild) Move one or more node(s) to our list of children. boolean isDerivedFrom(String typeNamespaceArg, String typeNameArg, int derivationMethod) Introduced in DOM Level 3. boolean isEqualNode(Node arg) DOM Level 3 WD- Experimental. boolean isId() DOM Level 3: isId Node item(int index) NodeList method: Return the Nth immediate child of this node, or null if the index is out of bounds. void makeChildNode() void normalize() Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are no adjacent Text nodes. Node removeChild(Node oldChild) Remove a child from this Node. Node replaceChild(Node newChild, Node oldChild) Make newChild occupy the location that oldChild used to have. void setIdAttribute(boolean id) NON-DOM: set the type of this attribute to be ID type. void setNodeValue(String value) Implicit in the rerouting of getNodeValue to getValue is the need to redefine setNodeValue, for symmetry's sake. void setOwnerDocument(CoreDocumentImpl doc) NON-DOM set the ownerDocument of this node and its children void setReadOnly(boolean readOnly, boolean deep) Override default behavior so that if deep is true, children are also toggled. void setSpecified(boolean arg) NON-DOM, for use by parser void setType(Object type) NON-DOM: used by the parser void setValue(String newvalue) The DOM doesn't clearly define what setValue(null) means. void synchronizeChildren() Override this method in subclass to hook in efficient internal data structure. String toString() NON-DOM method for debugging convenience

Node cloneNode(boolean deep) Returns a duplicate of a given node. short compareDocumentPosition(Node other) Compares a node with this node with regard to their position in the document. short compareTreePosition(Node other) This method is deprecated.
