XPathStaticContext.declareVariable介绍

[英]Declare a variable. A variable must be declared before an expression referring to it is compiled. The initial value of the variable will be the empty sequence. This method backs up the XPathEvaluator#declareVariable method.
[中]声明一个变量。在编译引用变量的表达式之前，必须声明变量。变量的初始值将是空序列。此方法支持XPathEvaluator#declareVariable方法。

代码示例

代码示例来源：origin: pmd/pmd

final String name = propertyDescriptor.name();
if (!"xpath".equals(name)) {
  final XPathVariable xpathVariable = xpathStaticContext.declareVariable(null, name);
  xpathVariables.add(xpathVariable);

代码示例来源：origin: net.sourceforge.saxon/saxon

/**
 * Declare a variable, making it available for use within a subsequently-compiled XPath expression.
 * The variable may subsequently be assigned a value using the method
 * {@link XPathDynamicContext#setVariable(XPathVariable, net.sf.saxon.om.ValueRepresentation)}.
 * Any external variable used in an XPath expression must be declared before the XPath expression
 * is compiled.
 * @param uri The namespace URI of the variable name. Use "" for the null namespace.
 * @param localName The local part of the variable name.
 * @return an object representing the variable
 */
public XPathVariable declareVariable(String uri, String localName) {
  return staticContext.declareVariable(uri, localName);
}
