Documentation

A trigger parameter dictionary holds a list of parameters and their values. Each parameter can be of type int, double, or string.

TrigPar(void)

Parameter dictionary default constructor.

TrigPar(const char *FileName)

Make a dictionary and add parameters as described by the file.

TrigPar(std::istream& file)

Make a dictionary and add parameters as described by the file.

~TrigPar(void)

Dictionary destructor.

bool exists(const std::string& ParName) const

Test whether the named parameter is defined.

Param& operator[](const std::string &Name)

The named parameter may be assigned a value (e.g. Dict["MyPar"] = 5;) or accessed (e.g. int = int(Dict["MyPar"]);) using the [] operator. If an undefined name is used on the left-hand-side of an assignment, the specified parameter is created with the type of the rhs of the assignment.

const Param& operator[](const std::string &Name) const

The named parameter may be assigned a value (e.g. Dict["MyPar"] = 5;) or accessed (e.g. int = int(Dict["MyPar"]);) using the [] operator. Referencing an undefined parameter will cause an exception.
