Extract from input stream
Restores the distribution parameters and any other internal data into distr from the textual representation provided by is.
distr will generate the same sequence of random numbers as if equivalent invocations of operator() were performed on the object of the same type from which the provided text was obtained.
- istream object from which the representation is extracted.
The textual representation provided by is shall have been obtained by a previous call to operator<< on an ostream object of the same type with the same locale imbued.
- Distribution object whose state and parameters are changed.
The same as parameter is.
A call to this function may set any of the internal state flags of is if:
(see ios_base::iostate for more info on these)
|eofbit||The end of the source of characters is reached during its operations.|
|failbit||The input obtained could not be interpreted as a valid textual representation of an object of this type.|
In this case, distr preserves the parameters and internal data it had before the call.
Notice that some eofbit cases will also set failbit.
|badbit||An error other than the above happened.|
Additionally, in any of these cases, if the appropriate flag has been set with is's member function ios::exceptions, an exception of type ios_base::failure is thrown.
