4) Copy constructor. If *this and other both have dynamic type std::tx_exception<T> then std::strcmp(what(),other.what())==0.
Parameters
value - payload object what_arg - explanatory string other - another exception object to copy Exceptions
1-3) May throw implementation-defined exceptions.
std::tx_exception::operator=
tx_exception&operator=(consttx_exception&other)transaction_safenoexcept;(TM TS)Assigns the contents with those of other. If *this and other both have dynamic type std::tx_exception<T> then std::strcmp(what(),other.what())==0 after assignment.
Parameters
other - another exception object to assign with Return value
*this
std::tx_exception::get
Tget()consttransaction_safe;(TM TS)Returns the payload object held by the exception object.
