Detailed Description

Class Message_Algorithm is intended to be the base class for classes implementing algorithms or any operations that need to provide extended information on its execution to the caller / user.

It provides generic mechanism for management of the execution status, collection and output of messages.

The algorithm uses methods SetStatus() to set an execution status. It is possible to associate a status with a number or a string (second argument of SetStatus() methods) to indicate precisely the item (object, element etc.) in the input data which caused the problem.

Each execution status generated by the algorithm has associated text message that should be defined in the resouce file loaded with call to Message_MsgFile::LoadFile().

The messages corresponding to the statuses generated during the algorithm execution are output to Message_Messenger using methods SendMessages(). If status have associated numbers or strings, they are included in the message body in place of "%s" placeholder which should be present in the message text.

The name of the message text in the resource file is constructed from name of the class and name of the status, separated by dot, for instance:

.TObj_CheckModel.Alarm2 Error: Some objects (s) have references to dead object(s)

If message for the status is not found with prefix of the current class type, the same message is searched for the base class(es) recursively.

Message can be set explicitly for the status; in this case the above procedure is not used and supplied message is used as is.

The messages are output to the messenger, stored in the field; though messenger can be changed, it is guaranteed to be non-null. By default, Message::DefaultMessenger() is used.

◆ AddStatus() [2/2]

void Message_Algorithm::AddStatus ( const Message_ExecStatus theStatus,
const Handle< Message_Algorithm > &  theOther

Add statuses to this algorithm from other algorithm, but only those items are moved that correspond to statuses set in theStatus.

◆ ChangeStatus()

Message_ExecStatus& Message_Algorithm::ChangeStatus ( )

Returns exec status of algorithm.

◆ ClearStatus()

void Message_Algorithm::ClearStatus ( )

Clear exec status of algorithm.

◆ GetMessageNumbers()

Handle< TColStd_HPackedMapOfInteger > Message_Algorithm::GetMessageNumbers ( const Message_Status theStatus) const

Return the numbers associated with the indicated status; Null handle if no such status or no numbers associated with it.

◆ GetMessageStrings()

Handle< TColStd_HSequenceOfHExtendedString > Message_Algorithm::GetMessageStrings ( const Message_Status theStatus) const

Return the strings associated with the indicated status; Null handle if no such status or no strings associated with it.

◆ GetMessenger()

Handle< Message_Messenger > Message_Algorithm::GetMessenger ( ) const

Returns messenger of algorithm. The returned handle is always non-null and can be used for sending messages.

◆ GetStatus()

const Message_ExecStatus& Message_Algorithm::GetStatus ( ) const

Returns copy of exec status of algorithm.

◆ PrepareReport() [1/2]

static TCollection_ExtendedString Message_Algorithm::PrepareReport ( const Handle< TColStd_HPackedMapOfInteger > &  theError,
const Standard_Integer  theMaxCount 
)
static

Prepares a string containing a list of integers contained in theError map, but not more than theMaxCount.

◆ PrepareReport() [2/2]

static TCollection_ExtendedString Message_Algorithm::PrepareReport ( const TColStd_SequenceOfHExtendedString theReportSeq,
const Standard_Integer  theMaxCount 
)
static

Prepares a string containing a list of names contained in theReportSeq sequence, but not more than theMaxCount.

◆ SendMessages()

void Message_Algorithm::SendMessages ( const Message_Gravity  theTraceLevel = Message_Warning,
const Standard_Integer  theMaxCount = 20 
) const

Convenient variant of SendStatusMessages() with theFilter having defined all WARN, ALARM, and FAIL (but not DONE) status flags.

◆ SendStatusMessages()

virtual void Message_Algorithm::SendStatusMessages ( const Message_ExecStatus theFilter,
const Message_Gravity  theTraceLevel = Message_Warning,
const Standard_Integer  theMaxCount = 20 
) const
virtual

Print messages for all status flags that have been set during algorithm execution, excluding statuses that are NOT set in theFilter.

The messages are taken from resource file, names being constructed as {dynamic class type}.{status name}, for instance, "Message_Algorithm.Fail5". If message is not found in resources for this class and all its base types, surrogate text is printed.

For the statuses having number or string parameters, theMaxCount defines maximal number of numbers or strings to be included in the message

Note that this method is virtual; this allows descendant classes to customize message output (e.g. by adding messages from other sub-algorithms)

Sets status with string parameter If noRepetitions is True, the parameter will be added only if it has not been yet recorded for the same status flag.

◆ SetStatus() [8/8]

void Message_Algorithm::SetStatus ( const Message_Status theStat,
