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.traversal.TreeWalker.firstChild.

Doc from org.w3c.dom.traversal.TreeWalker.firstChild.

Moves the TreeWalker to the first visible child of the current node, and returns the new node. If the current node has no visible children, returns null, and retains the current node.

Returns:Node

The new node, or null if the current node has no visible children in the TreeWalker's logical view.

Implements org.w3c.dom.traversal.TreeWalker.getCurrentNode.

Doc from org.w3c.dom.traversal.TreeWalker.getCurrentNode.

The node at which the TreeWalker is currently positioned.
Alterations to the DOM tree may cause the current node to no longer be accepted by the TreeWalker's associated filter. currentNode may also be explicitly set to any node, whether or not it is within the subtree specified by the root node or would be accepted by the filter and whatToShow flags. Further traversal occurs relative to currentNode even if it is not part of the current view, by applying the filters in the requested direction; if no traversal is possible, currentNode is not changed.

Implements org.w3c.dom.traversal.TreeWalker.getExpandEntityReferences.

Doc from org.w3c.dom.traversal.TreeWalker.getExpandEntityReferences.

The value of this flag determines whether the children of entity reference nodes are visible to the TreeWalker. If false, these children and their descendants will be rejected. Note that this rejection takes precedence over whatToShow and the filter, if any.
To produce a view of the document that has entity references expanded and does not expose the entity reference node itself, use the whatToShow flags to hide the entity reference node and set expandEntityReferences to true when creating the TreeWalker. To produce a view of the document that has entity reference nodes but no entity expansion, use the whatToShow flags to show the entity reference node and set expandEntityReferences to false.

Implements org.w3c.dom.traversal.TreeWalker.getFilter.

Doc from org.w3c.dom.traversal.TreeWalker.getFilter.

The filter used to screen nodes.

Implements org.w3c.dom.traversal.TreeWalker.getRoot.

Doc from org.w3c.dom.traversal.TreeWalker.getRoot.

The root node of the TreeWalker, as specified when it was created.

Implements org.w3c.dom.traversal.TreeWalker.getWhatToShow.

Doc from org.w3c.dom.traversal.TreeWalker.getWhatToShow.

This attribute determines which node types are presented via the TreeWalker. The available set of constants is defined in the NodeFilter interface. Nodes not accepted by whatToShow will be skipped, but their children may still be considered. Note that this skip takes precedence over the filter, if any.

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.traversal.TreeWalker.lastChild.

Doc from org.w3c.dom.traversal.TreeWalker.lastChild.

Moves the TreeWalker to the last visible child of the current node, and returns the new node. If the current node has no visible children, returns null, and retains the current node.

Returns:Node

The new node, or null if the current node has no children in the TreeWalker's logical view.

Implements org.w3c.dom.traversal.TreeWalker.nextNode.

Doc from org.w3c.dom.traversal.TreeWalker.nextNode.

Moves the TreeWalker to the next visible node in document order relative to the current node, and returns the new node. If the current node has no next node, or if the search for nextNode attempts to step upward from the TreeWalker's root node, returns null, and retains the current node.

Returns:Node

The new node, or null if the current node has no next node in the TreeWalker's logical view.

Implements org.w3c.dom.traversal.TreeWalker.nextSibling.

Doc from org.w3c.dom.traversal.TreeWalker.nextSibling.

Moves the TreeWalker to the next sibling of the current node, and returns the new node. If the current node has no visible next sibling, returns null, and retains the current node.

Returns:Node

The new node, or null if the current node has no next sibling. in the TreeWalker's logical view.

Implements org.w3c.dom.traversal.TreeWalker.parentNode.

Doc from org.w3c.dom.traversal.TreeWalker.parentNode.

Moves to and returns the closest visible ancestor node of the current node. If the search for parentNode attempts to step upward from the TreeWalker's root node, or if it fails to find a visible ancestor node, this method retains the current position and returns null.

Returns:Node

The new parent node, or null if the current node has no parent in the TreeWalker's logical view.

Implements org.w3c.dom.traversal.TreeWalker.previousNode.

Doc from org.w3c.dom.traversal.TreeWalker.previousNode.

Moves the TreeWalker to the previous visible node in document order relative to the current node, and returns the new node. If the current node has no previous node, or if the search for previousNode attempts to step upward from the TreeWalker's root node, returns null, and retains the current node.

Returns:Node

The new node, or null if the current node has no previous node in the TreeWalker's logical view.

Implements org.w3c.dom.traversal.TreeWalker.previousSibling.

Doc from org.w3c.dom.traversal.TreeWalker.previousSibling.

Moves the TreeWalker to the previous sibling of the current node, and returns the new node. If the current node has no visible previous sibling, returns null, and retains the current node.

Returns:Node

The new node, or null if the current node has no previous sibling. in the TreeWalker's logical view.

Implements org.w3c.dom.traversal.TreeWalker.setCurrentNode.

Doc from org.w3c.dom.traversal.TreeWalker.setCurrentNode.

The node at which the TreeWalker is currently positioned.
Alterations to the DOM tree may cause the current node to no longer be accepted by the TreeWalker's associated filter. currentNode may also be explicitly set to any node, whether or not it is within the subtree specified by the root node or would be accepted by the filter and whatToShow flags. Further traversal occurs relative to currentNode even if it is not part of the current view, by applying the filters in the requested direction; if no traversal is possible, currentNode is not changed.

Exceptions

DOMException:

NOT_SUPPORTED_ERR: Raised if an attempt is made to set currentNode to null.
