applies a coflatmap transformation on a connectedstreams andmaps the output to a common type . the transformation calls a coflatmapfunction #flatmap1 for each element of the first inputand coflatmapfunction #flatmap2 for each element of the secondinput . each coflatmapfunction call returns any number of elements including none . concode_field_sep StreamExecutionEnvironment environment concode_elem_sep DataStream<IN2> inputStream2 concode_elem_sep DataStream<IN1> inputStream1 concode_field_sep DataStream<IN2> getSecondInput concode_elem_sep StreamExecutionEnvironment getExecutionEnvironment concode_elem_sep DataStream<IN1> getFirstInput concode_elem_sep SingleOutputStreamOperator<R> transform concode_elem_sep ConnectedStreams<IN1,IN2> keyBy concode_elem_sep ConnectedStreams<IN1,IN2> keyBy concode_elem_sep ConnectedStreams<IN1,IN2> keyBy concode_elem_sep ConnectedStreams<IN1,IN2> keyBy concode_elem_sep ConnectedStreams<IN1,IN2> keyBy concode_elem_sep TypeInformation<IN1> getType1 concode_elem_sep TypeInformation<IN2> getType2 concode_elem_sep SingleOutputStreamOperator<R> map
