Verify that the Class Type of an object is DatasetMeta with warnings

This function that is a wrapper to the functions is_metacore and is_DatasetMeta.

This function is not intended to be called directly by the user.

If either of the wrapped functions return FALSE then execution is stopped and an appropriate error message is displayed.

Usage

verify_DatasetMeta(metacore)

Arguments

metacore

An object whose class type needs to be checked.

Value

Logical: TRUE if the class type of metacore is DatasetMeta, otherwise abort with errors.

adsl <- select_dataset(metacore, "ADSL", quiet = TRUE)
if (FALSE) { # \dontrun{
verify_DatasetMeta("DUMMY")   # Expect error
verify_DatasetMeta(metacore)  # Expect error
} # }
verify_DatasetMeta(adsl)      # Expect valid, i.e., return TRUE
