Here is a link to its current documentation . AD Output Stream Operator
Syntax
os << x

See Also
PrintFor

Purpose
Writes the Base value, corresponding to x , to the output stream os .

Assumption
If b is a Base object,



    os << b

returns a reference to os .

os
The operand os has prototype



    std::ostream& os

x
The operand x has one of the following prototypes



    const AD<Base>&               x

    const VecAD<Base>::reference& x

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



    AD<Base> y

then the syntax



    os << x << y

will output the value corresponding to x followed by the value corresponding 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_output.cpp contains an example and test of this operation.
