Example 1 with Transform

the class GistValidator method validateField.

private void validateField(Field f, RelativePropertyContext context) {
    String path = f.getPropertyPath();

        if (head.isCollection() && head.isPersisted()) {
            throw createIllegalProperty(field, "Property `%s` computes to many values and therefore cannot be used as a field.");
        }
    }
    Transform transformation = f.getTransformation();
    String transArgs = f.getTransformationArgument();
    if (transformation == Transform.PLUCK && transArgs != null) {
        Property plucked = context.switchedTo(getBaseType(field)).resolveMandatory(transArgs);
