Uses of SourceFunction in org.apache.flink.streaming.api.checkpoint

Subinterfaces of SourceFunction in org.apache.flink.streaming.api.checkpoint

Modifier and Type	Interface and Description
interface	ExternallyInducedSource<T,CD> Sources that implement this interface do not trigger checkpoints when receiving a trigger message from the checkpoint coordinator, but when their input data/events indicate that a checkpoint should be triggered.

Methods in org.apache.flink.streaming.api.environment with parameters of type SourceFunction

Modifier and Type	Method and Description
<OUT> DataStreamSource<OUT>	StreamExecutionEnvironment.addSource(SourceFunction<OUT> function) Adds a Data Source to the streaming topology.
<OUT> DataStreamSource<OUT>	StreamExecutionEnvironment.addSource(SourceFunction<OUT> function, String sourceName) Adds a data source with a custom type information thus opening a DataStream.
<OUT> DataStreamSource<OUT>	StreamExecutionEnvironment.addSource(SourceFunction<OUT> function, String sourceName, org.apache.flink.api.common.typeinfo.TypeInformation<OUT> typeInfo) Ads a data source with a custom type information thus opening a DataStream.
<OUT> DataStreamSource<OUT>	StreamExecutionEnvironment.addSource(SourceFunction<OUT> function, org.apache.flink.api.common.typeinfo.TypeInformation<OUT> typeInfo) Ads a data source with a custom type information thus opening a DataStream.

class	InputFormatSourceFunction<OUT> A SourceFunction that reads data using an InputFormat.
class	MessageAcknowledgingSourceBase<Type,UId> Abstract base class for data sources that receive elements from a message queue and acknowledge them back by IDs.
class	MultipleIdsMessageAcknowledgingSourceBase<Type,UId,SessionId> Abstract base class for data sources that receive elements from a message queue and acknowledge them back by IDs.
class	RichParallelSourceFunction<OUT> Base class for implementing a parallel data source.
class	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().
class	SocketTextStreamFunction A source function that reads strings from a socket.
