Constructor & Destructor Documentation

DtSimStatement::DtSimStatement

(

)

Default constructor.

DtSimStatement::DtSimStatement	(	const DtString &	name,
		DtReaderWriterRegistry *	parentRegistry = NULL
	)

Usual constructor NOTE: "name" should be the statement type string.

DtSimStatement::DtSimStatement	(	const DtSimStatement &	orig,
		DtReaderWriterRegistry *	parentRegistry = NULL
	)

Copy constructor.

virtual DtSimStatement::~DtSimStatement ( )

virtual

Destructor.

Member Function Documentation

virtual bool DtSimStatement::init ( )

virtual

Base class init does nothing, but this will be called by create, in case any other deriving class needs to do virtual allocation.

DtSimStatement& DtSimStatement::operator=

(

const DtSimStatement &

orig

)

Assignment operator (protected because this is an abstract base class).

virtual DtSimStatement* DtSimStatement::clone ( DtReaderWriterRegistry *  parentRegistry = NULL ) const

pure virtual

virtual copy constructor A typical clone function. It must be overridden by derived classes to return an exact copy of the object.

Implemented in DtUnregisterTriggerStatement, DtTriggerStmt, DtIfStmt, DtTaskStmt, DtRegisterTriggerStatement, DtDoUntilStmt, DtSimCommandStmt, DtSetDataRequestStmt, DtWhileStmt, and DtWaitUntilStmt.

virtual int DtSimStatement::type ( ) const

pure virtual

Returns the type of statement Type (defined in simStmtTypes.h)

Implemented in DtUnregisterTriggerStatement, DtRegisterTriggerStatement, DtTriggerStmt, DtIfStmt, DtTaskStmt, DtDoUntilStmt, DtSimCommandStmt, DtSetDataRequestStmt, DtWhileStmt, and DtWaitUntilStmt.

virtual bool DtSimStatement::validate ( )

virtual

Checks the statement for validity, and potentially fixes the statement to be valid.

Returns

True if the statement is valid.

Reimplemented in DtDoUntilStmt, and DtWhileStmt.

virtual void DtSimStatement::execute ( DtPlan &  planContext )

pure virtual

Execute the current statement and make any changes to the Plan state as appropriate. Tells the statement to activate its own behavior. Each kind of statement implements this function differently. It is passed a reference to the executing DtPlan object as a “context of execution”.

Implemented in DtTriggerStmt, DtRegisterTriggerStatement, DtDoUntilStmt, DtIfStmt, DtWhileStmt, DtTaskStmt, DtSimCommandStmt, DtSetDataRequestStmt, and DtWaitUntilStmt.

virtual void DtSimStatement::step ( DtPlan &  planContext, bool  forceStep = false  )

virtual

Asks the statement to step the context DtPlan to the next statement. The default implementation steps to the next statement in the same parent DtSimBlock. If this is the last statement in the Block, step() calls the block’s exitFromBlock() member function.

forceStep is unused

Reimplemented in DtSimCommandStmt, DtWaitUntilStmt, and DtIfStmt.

DtSimStatement * DtSimStatement::nextStmt ( ) const

inline

Return next (previous) statements in the block, or NULL if hit the end (beginning) of the list. Statement objects are derived from DtRwListedObj and these functions are wrappers for the base class next() and prev() member functions, which cast their return values to DtSimStatement pointers.

Inline functions.

References DtRwListedObj::next().

DtSimStatement * DtSimStatement::prevStmt ( ) const

inline

References DtRwListedObj::prev().

virtual DtStmtIdType DtSimStatement::statementId ( ) const

virtual

Statement Id accessors.

virtual void DtSimStatement::setStatementId ( DtStmtIdType  arg )

virtual

virtual DtSimBlock* DtSimStatement::parentBlock ( ) const

virtual

The parent statement Block. Returns a pointer to the surrounding DtSimBlock.

virtual void DtSimStatement::setParentBlock ( DtSimBlock *  arg )

virtual

virtual int DtSimStatement::subBlockCount ( ) const

virtual

Get the number of blocks nested inside this statement.

Reimplemented in DtTriggerStmt, DtIfStmt, DtRegisterTriggerStatement, DtDoUntilStmt, DtWhileStmt, and DtWaitUntilStmt.

virtual DtSimBlock* DtSimStatement::subBlock ( int  index )

virtual

Get a pointer to any particular block nested inside this statement. Sub-blocks are indexed as C arrays are (i.e. starting with block #0).

Reimplemented in DtTriggerStmt, DtIfStmt, DtDoUntilStmt, DtRegisterTriggerStatement, DtWhileStmt, and DtWaitUntilStmt.

virtual DtRecursiveSimStatementIterator* DtSimStatement::spawnRecursiveIterator ( ) const

virtual

Spawns an iterator that iterates over the subblocks in this statement, and all their children, sub children, etc.. The caller MUST DELETE the iterator when doen using it!

virtual DtSimStatement* DtSimStatement::lookupStatement ( DtStmtIdType  statementId )

virtual

If statementId matches our statement, returns a pointer to us. Otherwise calls lookupStatement() for each of our subblocks, if any.

virtual void DtSimStatement::setStatementDescription ( const DtString &  )

virtual

If supported for display a description of this statement that can be used for display.

virtual const DtString& DtSimStatement::statementDescription ( ) const

virtual

virtual DtString DtSimStatement::stringRep ( int  subBlockIndex = DtSR_STMT ) const

pure virtual

Get a readable string representation of this statement.

The subBlockIndex argument indicates which stringRep to get if this statement can have sub-blocks. If a sub-block index >= 0 is given, the string returned will be the one that should precede that sub-block. A sub-block index of DtSimStatement::DtSR_STMT requests the string that should follow any and all sub-blocks, this is the value that should be used for statements that have no subBlocks (i.e. subBlockCount() == 0).

Implemented in DtTriggerStmt, DtIfStmt, DtRegisterTriggerStatement, DtDoUntilStmt, DtWhileStmt, DtWaitUntilStmt, DtTaskStmt, DtSimCommandStmt, and DtSetDataRequestStmt.

virtual char* DtSimStatement::netRep ( )

virtual

virtual int DtSimStatement::netRepSize ( ) const

virtual

Returns sizeof(DtNetSimStatement). Derived classes should add this size to the size of their net representation (dervied class net reps should always put the DtNetSimStatement at the start of their buffer, and put their class specific data immediately following that).

Reimplemented in DtTriggerStmt, DtIfStmt, DtDoUntilStmt, DtWhileStmt, DtTaskStmt, DtRegisterTriggerStatement, DtSetDataRequestStmt, DtSimCommandStmt, and DtWaitUntilStmt.

virtual bool DtSimStatement::setFromNet ( const char *  contentBuffer, unsigned  contentSize  )

virtual

Extracts statement Id from buffer. First 16 bytes are a DtNetSimStatement structure. Derived class data should immediately follow this. Derived classes should call down to this one to make sure statement id gets set.

Reimplemented in DtTriggerStmt, DtIfStmt, DtDoUntilStmt, DtWhileStmt, DtTaskStmt, DtRegisterTriggerStatement, DtSetDataRequestStmt, DtSimCommandStmt, and DtWaitUntilStmt.

virtual bool DtSimStatement::setToNet ( )

virtual

Casts myNetRep to DtNetSimStatement* and fills in structure. Derived classes should always call down to this base class version to set the DtNetSimStatement structure at the beginning of the buffer. Any dervied data should immediately follow the DtNetSimStatement structure.

Reimplemented in DtTriggerStmt, DtIfStmt, DtDoUntilStmt, DtWhileStmt, DtRegisterTriggerStatement, DtTaskStmt, DtSetDataRequestStmt, DtSimCommandStmt, and DtWaitUntilStmt.

static DtStmtIdType DtSimStatement::generateNewStmtId ( )

static

static DtSimStatement* DtSimStatement::createStatement ( DtlObjPtr  mtlStream, DtReaderWriterRegistry *  parentRegistry = NULL  )

static

Static functions.

Construct an empty conditional expression of the appropriate type. Creates a new statement, given a pointer to an MTL stream. It parses the stream to extract the type of statement to create. Then it calls the statement factory’s create() member function with the statement type. This returns a new instance of the statement type. The statement’s getData() member function is then called to retrieve the statement from the stream. The pointer to the new statement is returned.

static DtSimStatement* DtSimStatement::createStatement ( int  statementType, DtReaderWriterRegistry *  parentRegistry = NULL  )

static

static void DtSimStatement::addStatementCreatorFcn ( const DtString &  type, int  intType, DtStatementCreatorFcn  fcn  )

static

Decodes a legacy stealth statement (VRF 3.9 and previous) and returns the proper statement for the current version. static DtSimStatement* createLegacyStealthStatement(DtlObjPtr mtlStream, DtReaderWriterRegistry* parentRegistry = NULL);.

Adds a statement creator member function to the statement factory.

static void DtSimStatement::setFactory ( DtStatementFactory *  factory )

static

static DtStatementFactory* DtSimStatement::factory ( )

static

static bool DtSimStatement::getStatementNameFromStatementType ( int  statementType, DtString &  statementName  )

static

static bool DtSimStatement::getStatementTypeFromStatementName ( const DtString &  statementName, int &  statementType  )

static

static bool DtSimStatement::addStatementTypeMapping ( const DtString &  statementName, int  taskType  )

static

static bool DtSimStatement::removeStatementTypeMapping ( const DtString &  statementName, int  statementType  )

static

virtual bool DtSimStatement::isSameStatement ( DtSimStatement *  )

virtual

Returns true if statements are equivalent. Will not check statementId.

virtual void DtSimStatement::upgradeTriggerUUID ( const boost::unordered_map< DtUUID, DtUUID > &  )

virtual

For those statements that need to, map from the old to new trigger UUID.

Reimplemented in DtTriggerStmt, DtIfStmt, DtRegisterTriggerStatement, DtDoUntilStmt, and DtWhileStmt.

virtual void DtSimStatement::reset ( )

virtual

Called when the plan is reset, will iterate over all statements to reset as well.

Reimplemented from DtReaderWriter.

Reimplemented in DtTriggerStmt, DtIfStmt, DtDoUntilStmt, and DtWhileStmt.

virtual char* DtSimStatement::createNetworkBuffer ( )

protectedvirtual

virtual bool DtSimStatement::compare ( DtSimStatement *  )

protectedvirtual

Called from isSameStatement. Compares net reps to see if they are the same. Override to do different comparrison.

Reimplemented in DtTriggerStmt, DtIfStmt, DtDoUntilStmt, DtWhileStmt, and DtWaitUntilStmt.
