Description

Get the operation that is using this object as its output

Syntax

OperationBase & GetIncomingOperation( BOOL bDirect, int & nOuputIndex )

Parameters

bDirect: [input] TRUE if this object is one of the direct output from the operation that we are trying to get,; and FALSE if this object may or may not be the direct output, it could be one of the children of the direct output object
nOuputIndex: [input] optional index for bDirect = FALSE case where multiple output objects are linked to the incoming operation, This index; can be used in other commands in OperationBase to identify the particular output.

Return

a valid operation wrapper that represent the internal operation object

Examples

EX1

// Example requires a graph on which some operation object analyses have been preformed.
// The code lists all the analyses
