Detailed Description

Class for blinding and unblinding a number based on a blinding string.

Numbers are blinded by applying an offset. The blinding string is converted to an integer using TMath::Hash and this integer is used to seed a TRandom3. The offset is sampled from a Gaussian of defined width using the seeded TRandom3.

Constructor & Destructor Documentation

LauBlind() [1/2]

LauBlind::LauBlind	(	const TString &	blindingStr,
		const Double_t	width
	)

Constructor.

Parameters

[in]	blindingStr	the blinding string
[in]	width	the width of the Gaussian for sampling the offset

Definition at line 41 of file LauBlind.cc.

LauBlind() [2/2]

LauBlind::LauBlind

(

)

Default constructor.

This is purely to allow I/O to succeed, should not generally be used

Definition at line 34 of file LauBlind.cc.
