evaluate
public Object evaluate(Context context)
throws JaxenException
Evaluates this predicate's expression and returns 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.
- evaluate in interface Predicate
context
- the context in which the expression is evaluated
- an object representing the result of the evaluation
getExpr
public Expr getExpr()
Returns the expression in this predicate.
- getExpr in interface Predicate
- the expression between the brackets
getText
public String getText()
Returns the string form of the predicate,
including the square brackets.
- getText in interface Predicate
- the bracketed form of this predicate
setExpr
public void setExpr(Expr expr)
Change the expression used by this predicate.
- setExpr in interface Predicate
expr
- the new expression
simplify
public void simplify()
Simplify the expression in this predicate.
- simplify in interface Predicate
