  • Method Details

    • getDependencies

      public Set<ObjectLocation> getDependencies()
      Gets an unmodifiable set of database object dependencies found in this expression.
      Returns:
      set of ObjectLocation representing dependencies

    • findReference

      public Map.Entry<String,ObjectReference> findReference(String schema, String name, String column)
      Parameters:
      schema - optional schema qualification of name, may be null
      name - alias of the referenced object
      column - optional referenced column alias, may be null
      Returns:
      a pair of (Alias, Dealiased name) where Alias is the given name. Dealiased name can be null if the name is internal to the query and is not a reference to external table.
      null if the name is not found
