Class Description

CIndexSet encapsulates an index set for indexing CDataArray object types for the current evaluation.

Example:

        XSIPLUGINCALLBACK CStatus YPosFilter_Evaluate( ICENodeContext& in_ctxt )
        {
                // The current output port being evaluated...
                ULONG out_portID = in_ctxt.GetEvaluatedOutputPortID( );

                switch( out_portID )
                {
                        case OutPort200:
                        {
                                CDataArrayVector3f inputData( ctxt, InPort0 );
                                CDataArrayVector3f outData( ctxt );

                                // We need a CIndexSet to iterate over the data
                                CIndexSet indexSet( in_ctxt );

                                for(CIndexSet::Iterator it = indexSet.Begin(); it.HasNext(); )
                                {
                                        outData[ it ] = inputData[ it ];

                                        if ( inputData[it].GetY() < 0.0 )
                                        {
                                                it.Remove( );
                                        }
                                        else
                                        {
                                                it.Next( );
                                        }
                                }
                        }
                        break;
                };

                return CStatus::OK;
        }

Constructor & Destructor Documentation

SICPPSDK_INLINE CIndexSet

(

const ICENodeContext &

in_ctxt

)

Constructor.

Parameters:

in_ctxt

ICENode evaluation context.

SICPPSDK_INLINE CIndexSet	(	const ICENodeContext &	in_ctxt,
		ULONG	in_nInputPortID,
		ULONG	in_nInstanceIndex = 0
	)

Constructor. Creates the index set for a specific port.

Note:

The CIndexSet created can not be used to set the output port data array and is only valid when the underlying custom ICENode is set with the siICENodeSingleThreading or siICENodeMultiEvaluationPhase mode. The object created is read-only, indices cannot be removed with CIndexSet::Iterator::Remove.

Parameters:

in_ctxt	ICENode evaluation context.
in_nInputPortID	Input port identifier.
in_nInstanceIndex	The group instance of the port.

SICPPSDK_INLINE ~CIndexSet

)
