Package org.apache.flink.streaming.api.functions.source

Interface Summary

Interface	Description
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.
TimestampedInputSplit	An extended InputSplit that also includes information about: The modification time of the file this split belongs to.

Class Summary

Class	Description
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,T extends TimestampedInputSplit>	The operator that reads the splits received from the preceding ContinuousFileMonitoringFunction.
ContinuousFileReaderOperatorFactory<OUT,T extends TimestampedInputSplit>	ContinuousFileReaderOperator factory.
FileMonitoringFunction	Deprecated Internal class deprecated in favour of ContinuousFileMonitoringFunction.
FileReadFunction	Deprecated 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	A FileInputSplit with TimestampedInputSplit.

Enum Summary

Enum	Description
FileMonitoringFunction.WatchType	The watch type of the FileMonitoringFunction.
FileProcessingMode	The mode in which the ContinuousFileMonitoringFunction operates.
