Class Method Details

.to_avro ⇒ Object 



57
 
# File 'lib/wukong/schema.rb', line 57

def to_avro() 'int'           end

.to_pig ⇒ Object 



28
 
# File 'lib/wukong/schema.rb', line 28

def to_pig() 'int'           end

.to_sql ⇒ Object 



8
 
# File 'lib/wukong/schema.rb', line 8

def to_sql() 'INT'                              end

.unbooleanize(bool) ⇒ Object

Express boolean as 1 (true) or 0 (false). In contravention of typical ruby semantics (but in a way that is more robust for wukong-like batch processing), the number 0, the string ‘0’, nil and false are all considered false. (This also makes the method idempotent: repeated calls give same result.)
