SequenceMapper

java.lang.Object
- net.sf.saxon.expr.SequenceMapper

All Implemented Interfaces:

MappingFunction
```
public class SequenceMapper
extends java.lang.Object
implements MappingFunction
```
SequenceMapper is an implementation of MappingFunction that wraps a function typically supplied as a lambda expression.
NOTE: Java allows a lambda expression to be used wherever a MappingFunction is needed, but C# does not (it's not possible in C# to have a class implementing a delegate). So if a lambda expression is wanted, use an SequenceMapper as a wrapper.
