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)
getOperator
public abstract java.lang.String getOperator()
- 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
getText
public java.lang.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
toString
public java.lang.String toString()
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.
