Module /fusion/lob
Operations on arrays of octets, also known as "lobs" (blob and clob).
(is_blob value)
Determines whether a value is of type blob, returning true or false.
(is_clob value)
Determines whether a value is of type clob, returning true or false.
(lob_digest lob algorithm)
Generates a message digest for the content of a lob, using
the given algorithm. The lob must be a non-null blob or clob containing the
bytes to be digested. The algorithm must be a string such as "SHA-256".
The result is a non-null blob.
Supported algorithms are "SHA-256" and "SHA-512".
(lob_to_hex lob)
Converts a lob to its hex encoding as a string. Returns null.string
when given null.clob or null.blob. The returned hex string does not
contain a '0x' prefix, and will only contain the characters [0-9a-f].
