Here is a link to its current documentation . AD Input Stream Operator
Syntax
is >> x

Purpose
Sets x to a parameter with value b corresponding to



    is >> b

where b is a Base object. It is assumed that this Base input operation returns a reference to is .

is
The operand is has prototype



    std::istream& is

x
The operand x has one of the following prototypes



    AD<Base>&               x

Result
The result of this operation can be used as a reference to is . For example, if the operand y has prototype



    AD<Base> y

then the syntax



    is >> x >> y

will first read the Base value of x from is , and then read the Base value to y .

Operation Sequence
The result of this operation is not an AD of Base object. Thus it will not be recorded as part of an AD of Base operation sequence .

Example
The file ad_input.cpp contains an example and test of this operation.
