boolean function ( ) { return isBernoulli ; }
indicates whether bernoulli or system sampling should be performed . bernoulli sampling requires the decision whether to include each row in the the sample to be independent across rows . system sampling allows implementation-dependent behavior . concode_field_sep boolean isRepeatable concode_elem_sep int repeatableSeed concode_elem_sep float samplingPercentage concode_elem_sep boolean isBernoulli concode_field_sep int getRepeatableSeed concode_elem_sep boolean isRepeatable concode_elem_sep float getSamplingPercentage
