ParallelSourceFunction<OUT> |
A stream data source that is executed in parallel.
|
SourceFunction<T> |
Base interface for all stream data sources in Flink.
|
SourceFunction.SourceContext<T> |
Interface that source functions use to emit elements, and possibly watermarks.
|
类 | 说明 |

ContinuousFileMonitoringFunction<OUT> |
This is the single (non-parallel) monitoring task which takes a
FileInputFormat
and, depending on the FileProcessingMode and the FilePathFilter , it is responsible for:
Monitoring a user-provided path. |
ContinuousFileReaderOperator<OUT> |
The operator that reads the
splits received from the preceding
ContinuousFileMonitoringFunction . |
FileMonitoringFunction | 已过时
Internal class deprecated in favour of
ContinuousFileMonitoringFunction . |
FileReadFunction | 已过时
Internal class deprecated in favour of
ContinuousFileMonitoringFunction . |
FromElementsFunction<T> |
A stream source function that returns a sequence of elements.
|
FromIteratorFunction<T> |
A
SourceFunction that reads elements from an Iterator and emits them. |
FromSplittableIteratorFunction<T> |
A
SourceFunction that reads elements from an SplittableIterator and emits them. |
InputFormatSourceFunction<OUT> |
A
SourceFunction that reads data using an InputFormat . |
MessageAcknowledgingSourceBase<Type,UId> |
Abstract base class for data sources that receive elements from a message queue and
acknowledge them back by IDs.
|
MultipleIdsMessageAcknowledgingSourceBase<Type,UId,SessionId> |
Abstract base class for data sources that receive elements from a message queue and
acknowledge them back by IDs.
|
RichParallelSourceFunction<OUT> |
Base class for implementing a parallel data source.
|
RichSourceFunction<OUT> |
Base class for implementing a parallel data source that has access to context information
(via
AbstractRichFunction.getRuntimeContext() ) and additional life-cycle methods
(AbstractRichFunction.open(org.apache.flink.configuration.Configuration) and AbstractRichFunction.close() . |
SocketTextStreamFunction |
A source function that reads strings from a socket.
|
StatefulSequenceSource |
A stateful streaming source that emits each number from a given interval exactly once,
possibly in parallel.
|
TimestampedFileInputSplit |
An extended
FileInputSplit that also includes information about:
The modification time of the file this split belongs to. |
枚举 | 说明 |
---|---|
FileMonitoringFunction.WatchType |
The watch type of the
FileMonitoringFunction . |
FileProcessingMode |
The mode in which the
ContinuousFileMonitoringFunction operates. |
