class pip_services3_commons.convert.IntegerConverter.IntegerConverter

Bases: object

Converts arbitrary values into integers using extended conversion __rules: - Strings are converted to floats, then to integers - DateTime: total number of milliseconds since unix epoсh - Boolean: 1 for true and 0 for false

Example:

value1 = IntegerConverter.to_nullable_integer("ABC")     # Result: None
value2 = IntegerConverter.to_nullable_integer("123.456") # Result: 123
value3 = IntegerConverter.to_nullable_integer(true)      # Result: 1
value4 = IntegerConverter.to_nullable_integer(datetime.datetime.now()) # Result: current milliseconds
