Example 4 with SequencerType

use of io.nosqlbench.engine.api.activityapi.planning.SequencerType in project nosqlbench by nosqlbench.

the class SimpleActivity method createOpSequence.

/**
 * Given a function that can create an op of type <O> from an OpTemplate, generate
 * an indexed sequence of ready to call operations.
 *
 * This method uses the following conventions to derive the sequence:
 *
 * <OL>
 * <LI>If an 'op', 'stmt', or 'statement' parameter is provided, then it's value is
 * taken as the only provided statement.</LI>
 * <LI>If a 'yaml, or 'workload' parameter is provided, then the statements in that file
 * are taken with their ratios </LI>
 * <LI>Any provided tags filter is used to select only the statements which have matching
 * tags. If no tags are provided, then all the found statements are included.</LI>
 * <LI>The ratios and the 'seq' parameter are used to build a sequence of the ready operations,
 * where the sequence length is the sum of the ratios.</LI>
 * </OL>
 *
 * @param opinit A function to map an OpTemplate to the executable operation form required by
 *               the native driver for this activity.
 * @param <O>    A holder for an executable operation for the native driver used by this activity.
 * @return The sequence of operations as determined by filtering and ratios
