Its inputs are several 00049 | multi-valued fields (automatic field conversion will do the 00050 | right thing, so you can attach single-valued fields) of the 00051 | same type, output is a multi-value field of the same type. 00052 | 00053 | If you need to concatenate more than 10 fields together, 00054 | concatenate the outputs of several of these into yet another 00055 | concatenate engine. 00056 | 00057 | Classes: 00058 | SoConcatenate 00059 | 00060 | Author(s) : Ronen Barzel, Gavin Bell 00061 | 00062 ______________ S I L I C O N G R A P H I C S I N C . ____________ 00063 _______________________________________________________________________ 00064 */ 00065 00066 #ifndef _SO_CONCATENATE_ 00067 #define _SO_CONCATENATE_ 00068 00069 #include <Inventor/system/SbSystem.h> 00070 #include <Inventor/engines/SoSubEngine.h> 00071 #include <Inventor/fields/SoSFName.h> 00072 00073 00074 class SoMField; 00075 00078 00107 00108 00109 class INVENTOR_API SoConcatenate : public SoEngine { 00110 00111 SO_ENGINE_HEADER(SoConcatenate); 00112 00113 public: 00114 00116 SoConcatenate(SoType mfInputType); 00117 00122 SoMField *input[10]; 00123 00126 SoEngineOutput *output; 00127 00128 SoINTERNAL public: 00130 static void initClass(); 00131 00132 protected: 00133 00134 virtual SoFieldContainer * copyThroughConnection() const; 00135 00136 private: 00139 SoConcatenate(); 00140 ~SoConcatenate(); 00141 00144 virtual SbBool readInstance(SoInput *in, unsigned short flags); 00145 virtual void writeInstance(SoOutput *out); 00146 00147 void setup(SoType); 00148 virtual void evaluate(); 00149 00150 int conversionCase; 00151 00152 SoFieldData *myInputData; 00153 SoEngineOutputData *myOutputData; 00154 00155 SoSFName typeField; 00156 }; 00157 00158 #endif /* _SO_CONCATENATE_ */
