Member Enumeration Documentation

enum ELAM::Exception::ErrorType

Type of Exception.

Enumerator:

NoError	not an exception
ParserError	error while parsing the expression
UnknownOperatorError	the operator is not known
UnknownFunctionError	the function is not known
UnknownValueError	unknown variable or constant
TypeMismatchError	the operator or function is known, but the type of one of the arguments is not supported
ArgumentListError	the amount of arguments to a function is wrong or the syntax of arguments
OperationError	the operation itself failed, e.g. division by zero
