LongConverter

The LongConverter class allows you to convert arbitrary values into longs using extended conversion rules.

Description

The LongConverter class allows you to convert arbitrary values into longs using the following extended conversion rules:

  • Strings are converted to floats, then to longs
  • DateTime: total number of milliseconds since unix epoch
  • Boolean: 1 for true and 0 for false

Static methods

to_long

Converts value into long or returns 0 when conversion is not possible.

static to_long(value: Any): float

  • value: Any - the value to convert.
  • returns: float - long value or 0 when conversion is not supported.

to_long_with_default

Converts value into integer or returns default when conversion is not possible.

static to_long_with_default(value: Any, defaultValue: float): float

  • value: Any - the value to convert.
  • default_value: float - the default value.
  • returns: float - long value or default when conversion is not supported

to_nullable_long

Converts value into long or returns None when conversion is not possible.

static to_nullable_long(value: Any): Optional[float]

  • value: Any - the value to convert.
  • returns: float - long value or None when conversion is not supported.

Examples

import datetime
value1 = LongConverter.to_nullable_long("ABC"); # Returns None
value2 = LongConverter.to_nullable_long("123.456"); # Returns 123
value3 = LongConverter.to_nullable_long(True); # Returns 1
value4 = LongConverter.to_nullable_long(datetime.datetime.now()); # Returns current milliseconds (E.g. 1619869474907)
