All known Subclasses: com.caucho.xpath.functions.ResolveURI, com.caucho.xpath.functions.Trace, com.caucho.xpath.functions.BaseURI,
AbstractStringExpr | abstract public class AbstractStringExpr extends Expr (Code) | | Implements the builtin XPath string expressions.
|
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 | abstract 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. |
isString | public boolean isString()(Code) | | The StringExpr returns a string value.
|
normalize | protected static String normalize(String string)(Code) | | Normalize the string, converting all whitespace to a space and
eliminating consecutive spaces.
