Referring to AndFilterOperator, all child FilterOperators are invoked on each call of nextBlock() invocation of the parent operator, hence each child operator generates a block on a single call of getNextBlock() for the parent. Isn't that exactly what this operator is doing as well? -- This is an automated message from the Apache Git Service.
