    Description copied from interface: Table
    
    Returns this table's row type.
    This is a struct type whose fields describe the names and types of the columns in this table.
    
    The implementer must use the type factory provided. This ensures that the type is converted into a canonical form; other equal types in the same query will use the same object.
    
    Specified by:
    
    getRowType in interface Table
    
    Parameters:
    
    typeFactory - Type factory with which to create the type
    
    Returns:
    
    Row type
