Class InputInfo provides methods to retrieve the metadata for a table operator. InputInfo provides access to the Map containing the Custom clause information and can use standard Map methods to retrieve items by index or name. Similarly, the columns that participate in the Hash or Ordering of the input are available from lists with the getHashBy and getOrderBy methods. A Map of function information is also available so you can retrieve the function name and any other attributes.
