Constructor Summary public   StringExpr(int code, Expr left, Expr right, Expr third)      Create a StringExpression with three arguments. public   StringExpr(int code, Expr left, Expr right)      public   StringExpr(int code, Expr expr)      public   StringExpr(String value)      public   StringExpr(int code, ArrayList args)      Creates a string expression from a list of arguments. Method Summary public  boolean evalBoolean(Node node, ExprEnvironment env)      Evaluate the expression as a boolean, i.e. public  double evalNumber(Node node, ExprEnvironment env)      Evaluate the expression as a double, i.e. public  Object evalObject(Node node, ExprEnvironment env)      Evaluate the expression as an object, i.e. public  String evalString(Node node, ExprEnvironment env)      Evaluates the expression as an string. Parameters:   node - the current node Parameters:   env - the variable environment. public  String getValue()      public  boolean isString()      The StringExpr returns a string value. public  String toString()      Return the expression as a string. Constructor Detail StringExpr public StringExpr(int code, Expr left, Expr right, Expr third)(Code) Create a StringExpression with three arguments. Parameters:   code - the Expr code of the expression. Parameters:   left - the first argument. Parameters:   right - the second argument. Parameters:   third - the third argument. StringExpr public StringExpr(int code, Expr left, Expr right)(Code) StringExpr public StringExpr(int code, Expr expr)(Code) StringExpr public StringExpr(String value)(Code) StringExpr public StringExpr(int code, ArrayList args)(Code) Creates a string expression from a list of arguments. Parameters:   code - Expr code for the function. Parameters:   args - array list of the arguments. Method Detail evalBoolean public boolean evalBoolean(Node node, ExprEnvironment env) throws XPathException(Code) Evaluate the expression as a boolean, i.e. evaluate it as a string and then convert it to a boolean. Parameters:   node - the current node Parameters:   env - the variable environment. the boolean representation of the expression. evalNumber public double evalNumber(Node node, ExprEnvironment env) throws XPathException(Code) Evaluate the expression as a double, i.e. evaluate it as a string and then convert it to a double. Parameters:   node - the current node Parameters:   env - the variable environment. the numeric representation of the expression. evalObject public Object evalObject(Node node, ExprEnvironment env) throws XPathException(Code) Evaluate the expression as an object, i.e. return the string value. Parameters:   node - the current node Parameters:   env - the variable environment. the boolean representation of the expression. evalString public String evalString(Node node, ExprEnvironment env) throws XPathException(Code) Evaluates the expression as an string. Parameters:   node - the current node Parameters:   env - the variable environment. the string representation of the expression. getValue public String getValue()(Code) isString public boolean isString()(Code) The StringExpr returns a string value. toString public String toString()(Code) Return the expression as a string. toString() returns a valid XPath expression. This lets applications like XSLT use toString() to print the string in the generated Java.
