Methods Summary
public void	callArgVisitors(com.sun.org.apache.xpath.internal.XPathVisitor visitor) see com.sun.org.apache.xpath.internal.XPathVisitable#callVisitors(ExpressionOwner, XPathVisitor) super.callArgVisitors(visitor); if(null != m_arg1) m_arg1.callVisitors(new Arg1Owner(), visitor);
public boolean	canTraverseOutsideSubtree() Tell if this expression or it's subexpressions can traverse outside the current subtree. return true if traversal outside the context node's subtree can occur. return super.canTraverseOutsideSubtree() ? true : m_arg1.canTraverseOutsideSubtree();
public void	checkNumberArgs(int argNum) Check that the number of arguments passed to this function is correct. param argNum The number of arguments that is being passed to the function. throws WrongNumberArgsException if (argNum != 2) reportWrongNumberArgs();
public boolean	deepEquals(com.sun.org.apache.xpath.internal.Expression expr) see Expression#deepEquals(Expression) if(!super.deepEquals(expr)) return false; if(null != m_arg1) { if(null == ((Function2Args)expr).m_arg1) return false; if(!m_arg1.deepEquals(((Function2Args)expr).m_arg1)) return false; } else if(null != ((Function2Args)expr).m_arg1) return false; return true;
public void	fixupVariables(java.util.Vector vars, int globalsSize) This function is used to fixup variables from QNames to stack frame indexes at stylesheet build time. param vars List of QNames that correspond to variables. This list should be searched backwards for the first qualified name that corresponds to the variable reference qname. The position of the QName in the vector from the start of the vector will be its position in the stack frame (but variables above the globalsTop value will need to be offset to the current stack frame). super.fixupVariables(vars, globalsSize); if(null != m_arg1) m_arg1.fixupVariables(vars, globalsSize);
public com.sun.org.apache.xpath.internal.Expression	getArg1() Return the second argument passed to the function (at index 1). return An expression that represents the second argument passed to the function. return m_arg1;
protected void	reportWrongNumberArgs() Constructs and throws a WrongNumberArgException with the appropriate message for this function object. throws WrongNumberArgsException throw new WrongNumberArgsException(XSLMessages.createXPATHMessage("two", null));
public void	setArg(com.sun.org.apache.xpath.internal.Expression arg, int argNum) Set an argument expression for a function. This method is called by the XPath compiler. param arg non-null expression that represents the argument. param argNum The argument number index. throws WrongNumberArgsException If the argNum parameter is greater than 1. // System.out.println("argNum: "+argNum); if (argNum == 0) super.setArg(arg, argNum); else if (1 == argNum) { m_arg1 = arg; arg.exprSetParent(this); } else reportWrongNumberArgs();
