DtSimCondExpr is an abstract base class representing various Conditional Expressions used by the Plan engine and triggers.

For those conditional expressions that can use a modifier for determining whether or not the conditional expression can apply to a pattern (DtCeCheckEntityIdentificationLevel, DtCeEntDestroyed, etc.) the pattern is defined as follows as a comma delimited text that must have the following format:

PATTERN,[ANY],[INVERT],<EXCLUDEDESTROYED|LOOKATALL>,[force number],[super type],[kind],[domain],[country],[category],[subcategory],[specific],[extra]

Once the keyword PATTERN is seen by the conditional expression it will know to look for the specific format supplied above to fill out the pattern match. Any item in a [] can be filled in or left blank. Any item in a <> must have one of the options selected.

If the keyword ANY is supplied it means that it will also apply to any subordinate of the entity this conditional is applied to also meets the requirement of the conditional If the keyword INVERT is supplied it means it will search for any pattern that is not the pattern specified If EXCLUDEDESTROYED is given destroyed objects will be excluded from the search Force number may be omitted to ignore force in a search. Examples:

Match only non-destroyed friendly M1A2s: PATTERN,,,EXCLUDEDESTROYED,1,1,1,1,225,1,1,3,0

Match all humans of any force: PATTERN,,,LOOKATALL,,1,3,-1,-1,-1,-1,-1,-1

virtual bool DtSimCondExpr::init ( )

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

DtSimCondExpr& DtSimCondExpr::operator= ( const DtSimCondExpr & orig )

virtual void DtSimCondExpr::setEvaluator ( DtEvaluator * evaluator )

virtual

Set the evaluator object to be used in our evaluate() function. Takes over responsiblity for deleting the memory associated with the DtEvaluator. You must set an evaluator if you intend to call evaluate() on the conditional expression.

DtEvaluator* DtSimCondExpr::evaluator ( )

inline

virtual bool DtSimCondExpr::evaluate	(	DtLocalObject *	owner,
		const DtSimulationServices *	simManager,
		const DtPlan *	= `0`
	)		const

virtual

Evaluate this conditional expression for the entity with the given object object plan (which will have the same UUID as the owner).

Uses the DtEvaluator object set in setEvaluator() to actually perform the evaluation. An evaluator must be set before this function is called. Evaluation is expected to be performed by back-ends only (remote-control applications such as GUIs will not typically call this function).

If issued from a plan, the owner is the owner of that plan

virtual int DtSimCondExpr::subExprCount ( ) const

virtual

Get the number of sub-expressions nested inside this expression.

Reimplemented in DtCeNot, and DtLogicalOperatorCondition.

virtual DtSimCondExpr* DtSimCondExpr::subExpr ( int index )

virtual

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

Reimplemented in DtCeNot, and DtLogicalOperatorCondition.

virtual DtString DtSimCondExpr::modifierStringRep ( const DtString & ) const

virtual

Given the modifier string, come up with a human readable name for it.

virtual DtString DtSimCondExpr::stringRep ( int subExprIndex = DtSR_EXPR ) const

pure virtual

Get a readable string representation of this level of this expression.

The subExprIndex argument indicates which stringRep to get if this expression can have sub-expressions. If a sub-expression index >= 0 is given, the string returned will be the one that should precede that sub-expression. A sub-expression index of DtSimCondExpr::DtSR_EXPR requests the string that should follow any and all sub-expressions, this is the value that should be used for expressions that have no subExprs (i.e. subExprCount() == 0).

Implemented in DtCeResourceOperator, DtCeAltitude, DtCeSimTime, DtCeNot, DtCeConstant, DtCeEntInArea, DtCeSurrender, DtCeCheckEntityIdentificationLevel, DtCeEntLeftOfLine, DtCeEntEmbarkationStateChange, DtCeRandom, DtCeEntDiGuyAnimation, DtCeEntDiGuyAppearance, vrfAddConditionalExample::MyConditionalExpression, DtCeEntHasTarget, DtCeEntUnderFire, DtCeEntDestroyed, DtCeScenarioEvent, DtCeEntIndependentlyTasked, DtCeReceiveTextMessage, DtCeBreached, DtCeEntityCreated, DtCeMissileApproachWarning, DtCeSimDateTime, DtCeEnvironmentalActive, DtCeSimTimeOfDay, DtCeAnd, DtCeOr, and DtCeSyncMatrixPlansCompleted.

DtString DtSimCondExpr::stringRepFull ( ) const

Get a readable string representation of this full expression. This calls stringRep and stringRepFull recursively for each subExpr and combines them into a single string.

virtual char* DtSimCondExpr::netRep ( )

virtual const DtUUID& DtSimCondExpr::simulationObject ( ) const

virtual

Static functions.

If there is a simulation object that has satisfied the requirement of this conditional expression it is returned from this statement. Calls down to evaluator to return the simulation object that was found during evaluation

static DtSimCondExpr* DtSimCondExpr::createCondExpr ( DtlObjPtr mtlStream )

static

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

static void DtSimCondExpr::addCondExprCreatorFcn	(	const DtString &	type,
		const int	intType,
		DtCondExprCreatorFcn	fcn

static

Adds a conditional expression creator member function to the conditional expression factory.
