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.

Annotations

@Override

Implements org.w3c.dom.xpath.XPathResult.getBooleanValue.

Doc from org.w3c.dom.xpath.XPathResult.getBooleanValue.

The value of this boolean result.

Implements org.w3c.dom.xpath.XPathResult.getInvalidIteratorState.

Doc from org.w3c.dom.xpath.XPathResult.getInvalidIteratorState.

Signifies that the iterator has become invalid. True if resultType is UNORDERED_NODE_ITERATOR_TYPE or ORDERED_NODE_ITERATOR_TYPE and the document has been modified since this result was returned.

Implements org.w3c.dom.xpath.XPathResult.getNumberValue.

Doc from org.w3c.dom.xpath.XPathResult.getNumberValue.

The value of this number result. If the native double type of the DOM binding does not directly support the exact IEEE 754 result of the XPath expression, then it is up to the definition of the binding binding to specify how the XPath number is converted to the native binding number.

Implements org.w3c.dom.xpath.XPathResult.getResultType.

Doc from org.w3c.dom.xpath.XPathResult.getResultType.

A code representing the type of this result, as defined by the type constants.

Implements org.w3c.dom.xpath.XPathResult.getSingleNodeValue.

Doc from org.w3c.dom.xpath.XPathResult.getSingleNodeValue.

The value of this single node result, which may be null.

Implements org.w3c.dom.xpath.XPathResult.getSnapshotLength.

Doc from org.w3c.dom.xpath.XPathResult.getSnapshotLength.

The number of nodes in the result snapshot. Valid values for snapshotItem indices are 0 to snapshotLength-1 inclusive.

Implements org.w3c.dom.xpath.XPathResult.getStringValue.

Doc from org.w3c.dom.xpath.XPathResult.getStringValue.

The value of this string result.

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

Annotations

@Override

Implements org.w3c.dom.xpath.XPathResult.iterateNext.

Doc from org.w3c.dom.xpath.XPathResult.iterateNext.

Iterates and returns the next node from the node set or nullif there are no more nodes.

Returns:Node

Returns the next node.

Exceptions

DOMException:

INVALID_STATE_ERR: The document has been mutated since the result was returned.

Implements org.w3c.dom.xpath.XPathResult.snapshotItem.

Doc from org.w3c.dom.xpath.XPathResult.snapshotItem.

Returns the indexth item in the snapshot collection. If index is greater than or equal to the number of nodes in the list, this method returns null. Unlike the iterator result, the snapshot does not become invalid, but may not correspond to the current document if it is mutated.

Parameters

index:int

Index into the snapshot collection.

Returns:Node

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