ca.ecliptical.emf.xpath.EMFDOMXPath.numberValueOf()
ca.ecliptical.emf.xpath.EMFXPath.numberValueOf()
org.dom4j.Element.numberValueOf()
org.dom4j.XPath.numberValueOf()

numberValueOf evaluates an XPath expression and returns the numeric value of the XPath expression if the XPath expression results is a number, or null if the result is not a number.
@param context is either a node or a list of nodes on which to evalute theXPath @return the numeric result of the XPath expression or null if the resultis not a number.
org.jaxen.BaseXPath.numberValueOf()
Retrieve a number-value interpretation of this XPath expression when evaluated against a given context.
The number-value of the expression is determined per the number(..) core function as defined in the XPath specification. This means that if this expression selects multiple nodes, the number-value of the first node is returned.
@param node The node, nodeset or Context object for evaluation. This value can be null. @return The number-value interpretation of this expression.
org.jaxen.XPath.numberValueOf()
Retrieve a number-value interpretation of this XPath expression when evaluated against a given context.
The number-value of the expression is determined per the number(..) core function as defined in the XPath specification. This means that if this expression selects multiple nodes, the number-value of the first node is returned.
@param The node, nodeset or Context object for evaluation. This value can be null @return The number-value interpretation of this expression.
org.jaxen.dom.DOMXPath.numberValueOf()
org.jdom.xpath.XPath.numberValueOf()
Returns the number value of the first node selected by applying the wrapped XPath expression to the given context. @param context the element to use as context for evaluatingthe XPath expression. @return the number value of the first node selected by applyingthe wrapped XPath expression to the given context, null if no node was selected or the special value {@link java.lang.Double#NaN}(Not-a-Number) if the selected value can not be converted into a number value. @throws JDOMException if the XPath expression is invalid orits evaluation on the specified context failed.
