    Class TermTypeError

    Error thrown when the type of a term is unexpected.

    Code working with RDF might expect that a term (e.g. the object of a statement is of a specific term type (e.g. Literal}). When unmet, code might be strict and throw an error representing the failed expectation.

    The underlying error's term is the one whose type was unexpected.

    Consider the following mapping class, which expects a numeric literal:

    class Class extends TermWrapper {
        public get property(): number {
            return RequiredFrom.subjectPredicate(this, "p", LiteralAs.number)
        }
    }

    Given the following RDF, which does not meet the above expectation:

    <s> <p> <o> .

    Invoking the mapping code in the following manner:

    new Class("s", dataset, factory).property

    Will result in this error being throw with the following message.
