Overload:

__init__(self, in_0: IMSWeights) → None

Methods

`__init__`	Overload:
`back`(self)	Gets a last weight
`divideByGCD`(self)	Divides the integer weights by their gcd.
`getAlphabetMass`(self, i)	Gets an original (double) alphabet mass by index
`getMaxRoundingError`(self)
`getMinRoundingError`(self)
`getParentMass`(self, decomposition)	Returns a parent mass for a given decomposition
`getPrecision`(self)	Gets precision.
`getWeight`(self, i)	Gets a scaled integer weight by index
`setPrecision`(self, precision)	Sets a new precision to scale double values to integer
`size`(self)	Gets size of a set of weights
`swap`(self, index1, index2)	Exchanges weight and mass at index1 with weight and mass at index2

back(self) → int#: Gets a last weight

divideByGCD(self) → bool#: Divides the integer weights by their gcd. The precision is also adjusted

getAlphabetMass(self, i: int) → float#: Gets an original (double) alphabet mass by index

getMaxRoundingError(self) → float#

getMinRoundingError(self) → float#

getParentMass(self, decomposition: List[int]) → float#: Returns a parent mass for a given decomposition

getPrecision(self) → float#: Gets precision.

getWeight(self, i: int) → int#: Gets a scaled integer weight by index

setPrecision(self, precision: float) → None#: Sets a new precision to scale double values to integer

size(self) → int#: Gets size of a set of weights

swap(self, index1: int, index2: int) → None#: Exchanges weight and mass at index1 with weight and mass at index2
