FNValidate
public FNValidate(InputInfo ii,
Function f,
Expr... e)
- Constructor.
- Parameters:
ii
- input infof
- function definitione
- arguments
iter
public Iter iter(QueryContext ctx)
throws QueryException
- Description copied from class:
Expr
- Evaluates the expression and returns an iterator on the resulting items.
If this method is not overwritten,
Expr.item(org.basex.query.QueryContext, org.basex.util.InputInfo)
must be implemented
by an expression, as it may be called by this method.
- Overrides:
iter
in class ParseExpr
- Parameters:
ctx
- query context
- Returns:
- resulting item
- Throws:
QueryException
- query exception
value
public Value value(QueryContext ctx)
throws QueryException
- Description copied from class:
Expr
- Evaluates the expression and returns the resulting value.
- Overrides:
value
in class ParseExpr
- Parameters:
ctx
- query context
- Returns:
- iterator
- Throws:
QueryException
- query exception
item
public Item item(QueryContext ctx,
InputInfo ii)
throws QueryException
- Description copied from class:
Expr
- Evaluates the expression and returns the resulting item or
a
null
reference, if the expression yields an empty sequence.
If this method is not overwritten, Expr.iter(org.basex.query.QueryContext)
must be implemented
by an expression, as it may be called by this method.
- Overrides:
item
in class ParseExpr
- Parameters:
