Detailed Description

Objects of this class represent an exception in the evaluation of an ELAM expression.

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

Constructor & Destructor Documentation

ELAM::Exception::Exception

(

const Exception &

)

instantiates a copy of an exception

ELAM::Exception::Exception

(

const QVariant &

)

instantiate a copy from a matching variant

ELAM::Exception::Exception	(	ErrorType	type = NoError,
		QString	errorText = QString(),
		Position	pos = Position()
	)

instantiates an exception

Parameters

type	the type of exception
errorText	some human readable text describing the problem
pos	the position in the original expression string where the problem occurred

ELAM::Exception::Exception	(	ErrorType	type,
		Position	pos,
		QString	errorText = QString()
	)

instantiates an exception

Parameters

type	the type of exception
errorText	some human readable text describing the problem
pos	the position in the original expression string where the problem occurred
