  • public class SpinFunctionMapper
    extends FunctionMapper
    A FunctionMapper which resolves the Spin functions for Expression Language.

    Lazy loading: This implementation supports lazy loading: the Java Methods are loaded upon the first request.

    Caching: once the methods are loaded, they are cached in a Map for efficient retrieval.
