List of evaluateSingle() Examples

Examples of evaluateSingle()

net.sf.saxon.query.XQueryExpression.evaluateSingle()
Execute the compiled Query, returning the first item in the result. This is useful where it is known that the expression will only return a singleton value (for example, a single node, or a boolean). @param env Provides the dynamic query evaluation context @return The first item in the sequence returned by the expression. If the expressionreturns an empty sequence, this method returns null. Otherwise, it returns the first item in the result sequence, represented as a Java object using the same mapping as for the {@link XQueryExpression#evaluate evaluate} method
net.sf.saxon.sxpath.XPathExpression.evaluateSingle()
Execute the expression, returning the result as a single {@link net.sf.saxon.om.Item}If the result of the expression is a sequence containing more than one item, items after the first are discarded. If the result is an empty sequence, the method returns null. @param context the XPath dynamic context @return the first item in the result of the expression, or null
net.sf.saxon.xpath.XPathEvaluator.evaluateSingle()
Prepare and execute an XPath expression, supplied as a string, and returning the first item in the result. This is useful where it is known that the expression will only return a singleton value (for example, a single node, or a boolean). @param expression The XPath expression to be evaluated, supplied as a string. @return The first item in the sequence returned by the expression. If the expressionreturns an empty sequence, this method returns null. Otherwise, it returns the first item in the result sequence, represented as a Java object using the same mapping as for the evaluate() method @deprecated since Saxon 8.9 - use the methods defined in the JAXP interface
net.sf.saxon.xpath.XPathExpression.evaluateSingle()
Execute a prepared XPath expression, returning the first item in the result. This is useful where it is known that the expression will only return a singleton value (for example, a single node, or a boolean). @return The first item in the sequence returned by the expression. If the expressionreturns an empty sequence, this method returns null. Otherwise, it returns the first item in the result sequence, represented as a Java object using the same mapping as for the evaluate() method
org.pdf4j.saxon.sxpath.XPathExpression.evaluateSingle()
Execute the expression, returning the result as a single {@link org.pdf4j.saxon.om.Item}If the result of the expression is a sequence containing more than one item, items after the first are discarded. If the result is an empty sequence, the method returns null. @param context the XPath dynamic context @return the first item in the result of the expression, or null
