- All Implemented Interfaces:
public class CallableDelegate extends java.lang.Object implements CallableAn implementation of
Callablethat allows the logic to be supplied as a lambda expression.
On Java, it's possible to assign a lambda expression directly to a Callable. But on C#, a Callable isn't a delegate, so lambda expressions can't be used directly; instead, this class is provided as a proxy.

call(XPathContext context, Sequence arguments)Call the Callable.
public Sequence call(XPathContext context, Sequence arguments) throws XPathExceptionDescription copied from interface:
CallableCall the Callable.
- Specified by:
context- the dynamic evaluation context
arguments- the values of the arguments, supplied as Sequences.
Generally it is advisable, if calling iterate() to process a supplied sequence, to call it only once; if the value is required more than once, it should first be converted to a
GroundedValueby calling the utility method SequenceTool.toGroundedValue().
It is the caller's responsibility to perform any type conversions required to convert arguments to the type expected by the callee. An exception is where this Callable is explicitly an argument-converting wrapper around the original Callable.
- the result of the evaluation, in the form of a Sequence. It is the responsibility of the callee to ensure that the type of result conforms to the expected result type.
XPathException- if a dynamic error occurs during the evaluation of the expression
