Detailed Description

Class for managing status values (like errors or warning)

The RetVal class is used for handling return codes. All classes should use this class. In case an error occurs, only the first error is stored and will not be overridden by potentially subsequent occurring errors. An error is more severe than a warning and will overwrite a warning if it is added to an existing RetVal.

Constructor & Destructor Documentation

ito::RetVal::RetVal ( ito::tRetValue  retValue,
int  retCode,
const char *  pRetMessage 
)

constructor with retValue, retCode and errorMessage

Parameters
[in]retValuetype of RetVal; for possible values see tRetValue
[in]retCodeuser definable return code
[in]pRetMessageerror message to be passed or NULL, string is copied Makes a deep copy of RetVal, i.e. a copy of the error message

Member Function Documentation

int ito::RetVal::containsError ( ) const
inline

check if any error has occurred in this return value (true), else (false)

int ito::RetVal::containsWarning ( ) const
inline

check if any warning has occurred in this return value (true), else (false)

int ito::RetVal::containsWarningOrError ( ) const
inline

check if any warning or error has occurred in this return value (true), else (false)

int ito::RetVal::errorCode ( ) const
inline

return the error code (default: 0)

const char* ito::RetVal::errorMessage ( ) const
inline

return zero-terminated error message or empty, zero-terminated string if no error message has been set

RetVal ito::RetVal::format ( ito::tRetValue  retValue,
int  retCode,
const char *  pRetMessage,
  ... 
)
static

create RetVal with message that may contain placeholders using the formalism of the default sprintf method.

Parameters
retValueis the type of RetVal (retOk, retWarning, retError)
retCodeis the code number of RetVal
pRetMessageis the zero-terminated message string that may contain placeholders like s, i, ... (see sprintf)
...are further arguments. Their number and type must correspond to the placeholders in pRetMessage
Returns
created RetVal
bool ito::RetVal::hasErrorMessage ( ) const
inline

return true if an error or warning message is available

char ito::RetVal::operator!= ( const RetVal rhs)
inline

unequality operator compares retValue with with retValue of rhs RetVal. For possible constant values see tRetValue

char ito::RetVal::operator!= ( const tRetValue  rhs)
inline

unequality operator compares retValue with tRetValue constant. For possible constant values see tRetValue

RetVal ito::RetVal::operator+ ( const RetVal rhs)
inline

Concatenation of RetVal See operator RetVal::operator+=

RetVal & ito::RetVal::operator+= ( const RetVal rhs)

Concatenation of RetVal "Adds" RetVals, i.e. returns the most serious error. In case of equally serious errors the first is retained

RetVal & ito::RetVal::operator= ( const RetVal rhs)

assignment operator, copies values of rhs to current RetVal. Before copiing current errorMessage is freed

char ito::RetVal::operator== ( const RetVal rhs)
inline

equality operator compares retValue with with retValue of rhs RetVal. For possible constant values see tRetValue

char ito::RetVal::operator== ( const tRetValue  rhs)
inline

equality operator compares retValue with tRetValue constant. For possible constant values see tRetValue

Member Data Documentation

int ito::RetVal::m_retCode
private

the error code itself

ByteArray ito::RetVal::m_retMessage
private

message of this RetVal using ByteArray (using implicit sharing)

tRetValue ito::RetVal::m_retValue

can be one of enumeration tLogLevel values or an or-combination of these values
