getDataLayoutIndex()

virtual int32_t getDataLayoutIndex ( ) const

pure virtual

get the index of attribute within the data layout

For import classes that provide configurable attribute import, the layout index can only be access AFTER prepareForReading was called, since the actual data layout and the corresponding indices are typcially constructed/collected there.
