Examples of QueryBindings

com.foundationdb.qp.operator.QueryBindings
The bindings associated with the execution of a query. This includes query parameters (? markers) as well as current values for iteration. More than one QueryBindings may be active at the same time if iteration is being done in parallel for pipelining.
