Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters

that:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

Implements org.w3c.dom.NamedNodeMap.getLength.

Doc from org.w3c.dom.NamedNodeMap.getLength.

The number of nodes in this map. The range of valid child node indices is 0 to length-1 inclusive.

Implements org.w3c.dom.NamedNodeMap.getNamedItem.

Doc from org.w3c.dom.NamedNodeMap.getNamedItem.

Retrieves a node specified by name.

Parameters

name:String

The nodeName of a node to retrieve.

Returns:Node

A Node (of any type) with the specified nodeName, or null if it does not identify any node in this map.

Implements org.w3c.dom.NamedNodeMap.getNamedItemNS.

Doc from org.w3c.dom.NamedNodeMap.getNamedItemNS.

Retrieves a node specified by local name and namespace URI.
Per [XML Namespaces] , applications must use the value null as the namespaceURI parameter for methods if they wish to have no namespace.

Parameters

namespaceURI:String

The namespace URI of the node to retrieve.

localName:String

The local name of the node to retrieve.

Returns:Node

A Node (of any type) with the specified local name and namespace URI, or null if they do not identify any node in this map.

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns:int

a hash code value for this object

@Override

Implements org.w3c.dom.NamedNodeMap.item.

Doc from org.w3c.dom.NamedNodeMap.item.

Returns the indexth item in the map. If index is greater than or equal to the number of nodes in this map, this returns null.

Parameters

index:int

Index into this map.

Returns:Node

The node at the indexth position in the map, or null if that is not a valid index.

Implements org.w3c.dom.NamedNodeMap.removeNamedItem.

Doc from org.w3c.dom.NamedNodeMap.removeNamedItem.

Removes a node specified by name. When this map contains the attributes attached to an element, if the removed attribute is known to have a default value, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable.

Parameters

name:String

The nodeName of the node to remove.

Returns:Node

The node removed from this map if a node with such a name exists.

Exceptions

DOMException:

NOT_FOUND_ERR: Raised if there is no node named name in this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.

Implements org.w3c.dom.NamedNodeMap.removeNamedItemNS.

Doc from org.w3c.dom.NamedNodeMap.removeNamedItemNS.

Removes a node specified by local name and namespace URI. A removed attribute may be known to have a default value when this map contains the attributes attached to an element, as returned by the attributes attribute of the Node interface. If so, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable.
Per [XML Namespaces] , applications must use the value null as the namespaceURI parameter for methods if they wish to have no namespace.

Parameters

namespaceURI:String

The namespace URI of the node to remove.

localName:String

The local name of the node to remove.

Returns:Node

The node removed from this map if a node with such a local name and namespace URI exists.

Exceptions

DOMException:

NOT_FOUND_ERR: Raised if there is no node with the specified namespaceURI and localName in this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.
NOT_SUPPORTED_ERR: May be raised if the implementation does not support the feature "XML" and the language exposed through the Document does not support XML Namespaces (such as [HTML 4.01]).

Implements org.w3c.dom.NamedNodeMap.setNamedItem.

Doc from org.w3c.dom.NamedNodeMap.setNamedItem.

Adds a node using its nodeName attribute. If a node with that name is already present in this map, it is replaced by the new one. Replacing a node by itself has no effect.
As the nodeName attribute is used to derive the name which the node must be stored under, multiple nodes of certain types (those that have a "special" string value) cannot be stored as the names would clash. This is seen as preferable to allowing nodes to be aliased.

Parameters

node:Node

A node to store in this map. The node will later be accessible using the value of its nodeName attribute.

Returns:Node

If the new Node replaces an existing node the replaced Node is returned, otherwise null is returned.

Exceptions

DOMException:

WRONG_DOCUMENT_ERR: Raised if arg was created from a different document than the one that created this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.
INUSE_ATTRIBUTE_ERR: Raised if arg is an Attr that is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.
HIERARCHY_REQUEST_ERR: Raised if an attempt is made to add a node doesn't belong in this NamedNodeMap. Examples would include trying to insert something other than an Attr node into an Element's map of attributes, or a non-Entity node into the DocumentType's map of Entities.

Implements org.w3c.dom.NamedNodeMap.setNamedItemNS.

Doc from org.w3c.dom.NamedNodeMap.setNamedItemNS.

Adds a node using its namespaceURI and localName. If a node with that namespace URI and that local name is already present in this map, it is replaced by the new one. Replacing a node by itself has no effect.

Parameters

node:Node

A node to store in this map. The node will later be accessible using the value of its namespaceURI and localName attributes.

Returns:Node

If the new Node replaces an existing node the replaced Node is returned, otherwise null is returned.
