Constructor Detail

DefaultUnionExpr

public DefaultUnionExpr(Expr lhs,
                        Expr rhs)
Deprecated. 
Method Detail

getOperator

public String getOperator()
Deprecated. 
Description copied from interface: BinaryExpr
Returns the operator for the binary expression such as "+" or "div".

Specified by:
getOperator in interface BinaryExpr
Returns:
the operator for the expression

toString

public String toString()
Deprecated. 

evaluate

public Object evaluate(Context context)
                throws JaxenException
Deprecated. 
Description copied from interface: Expr
Evaluate the expression in the given context, and return the result. The result will be a java.lang.Double for expressions that return a number, a java.lang.String for expressions that return a string, a java.lang.Boolean for expressions that return a boolean, and a java.util.List for expressions that return a node-set. In the latter case, the elements of the list are the actual objects from the source document model. Copies are not made.

Specified by:
evaluate in interface Expr
Parameters:
context - the context in which the expression is evaluated
Returns:
an object representing the result of the evaluation
Throws:
JaxenException

getLHS

public Expr getLHS()
Description copied from interface: BinaryExpr
Returns the left-hand side of the binary expression.

Specified by:
getLHS in interface BinaryExpr
Returns:
the left hand side expression

getRHS

public Expr getRHS()
Description copied from interface: BinaryExpr
Returns the right-hand side of the binary expression.

Specified by:
getRHS in interface BinaryExpr
Returns:
the right-hand side expression

setLHS

public void setLHS(Expr lhs)

setRHS

public void setRHS(Expr rhs)

getText

public String getText()
Description copied from interface: Expr
Returns a String containing the XPath expression.

Specified by:
getText in interface Expr
Returns:
the text form of this XPath expression

simplify

public Expr simplify()
Description copied from interface: Expr
Simplifies the XPath expression. For example, the expression //para[1 = 1] could be simplified to //para. In practice, this is usually a noop. Jaxen does not currently perform any simplification.

Specified by:
simplify in interface Expr
Overrides:
simplify in class DefaultExpr
Returns:
the simplified expression
