Method Details

getOp

public DDBQueryOp getOp(long cycle)

Description copied from interface: OpDispenser

This method should do all the work of creating an operation that is executable by some other caller. The value produced by the apply method should not require additional processing if a caller wants to execute the operation multiple times, as for retries.

Parameters:

cycle - The cycle number which serves as the seed for any generated op fields to be bound into an operation.

Returns:

an executable operation
