Parameters:
in - where we read the expression from
Parameters:
messages - where to write syntax errors
Parameters:
item - becomes the context item while evaluating the expression
Parameters:
position - becomes the context position
Parameters:

out - where to send the result of the expression |
| eval_with_focus$X | | public void eval_with_focus$X(String expr, Object values, CallContext ctx) throws Throwable(Code) | | Evaluate an expression with a given focus (context).
Similar to evalWithFocus(String, Object, Consumer).
The "$X" in the method name tells the Kawa compiler that the CallContext
argument is implicit, so it can be invoked from XQuery code thus:
XQuery:eval-with-focus($xquery, "expr", $sequence)
|
| eval_with_focus$X | | public void eval_with_focus$X(String expr, Object item, int position, int size, CallContext ctx) throws Throwable(Code) | | Evaluate an expression with a given focus (context).
Similar to evalWithFocus(String, Object, int, int, Consumer).
The "$X" in the method name tells the Kawa compiler that the CallContext
argument is implicit, so it can be invoked from XQuery code thus:
XQuery:eval-with-focus($xquery, "expr", $item, $pos, $size)
