UnaryOperation

• java.lang.Object
  • com.sun.org.apache.xpath.internal.Expression

Fields Summary
protected Expression	m_right The operand for the operation.

Constructors Summary

Methods Summary
public void	callVisitors(com.sun.org.apache.xpath.internal.ExpressionOwner owner, com.sun.org.apache.xpath.internal.XPathVisitor visitor) see XPathVisitable#callVisitors(XPathVisitor) if(visitor.visitUnaryOperation(owner, this)) { m_right.callVisitors(this, 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. if (null != m_right && m_right.canTraverseOutsideSubtree()) return true; return false;
public boolean	deepEquals(com.sun.org.apache.xpath.internal.Expression expr) see Expression#deepEquals(Expression) if(!isSameClass(expr)) return false; if(!m_right.deepEquals(((UnaryOperation)expr).m_right)) return false; return true;
public com.sun.org.apache.xpath.internal.objects.XObject	execute(com.sun.org.apache.xpath.internal.XPathContext xctxt) Execute the operand and apply the unary operation to the result. param xctxt The runtime execution context. return An XObject that represents the result of applying the unary operation to the evaluated operand. throws javax.xml.transform.TransformerException return operate(m_right.execute(xctxt));
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). m_right.fixupVariables(vars, globalsSize);
public com.sun.org.apache.xpath.internal.Expression	getExpression() see ExpressionOwner#getExpression() return m_right;
public com.sun.org.apache.xpath.internal.Expression	getOperand() return the operand of unary operation, as an Expression. return m_right;
public abstract com.sun.org.apache.xpath.internal.objects.XObject	operate(com.sun.org.apache.xpath.internal.objects.XObject right) Apply the operation to two operands, and return the result. param right non-null reference to the evaluated right operand. return non-null reference to the XObject that represents the result of the operation. throws javax.xml.transform.TransformerException
public void	setExpression(com.sun.org.apache.xpath.internal.Expression exp) see ExpressionOwner#setExpression(Expression) exp.exprSetParent(this); m_right = exp;
public void	setRight(com.sun.org.apache.xpath.internal.Expression r) Set the expression operand for the operation. param r The expression operand to which the unary operation will be applied. m_right = r; r.exprSetParent(this);
