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) Ads 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.

Uses of SourceFunction in org.apache.flink.streaming.api.functions.source

Subinterfaces of SourceFunction in org.apache.flink.streaming.api.functions.source

Modifier and Type	Interface and Description
interface	ParallelSourceFunction<OUT> A stream data source that is executed in parallel.

Classes in org.apache.flink.streaming.api.functions.source that implement SourceFunction

Modifier and Type	Class and Description
class	ConnectorSource<OUT>
class	ContinuousFileMonitoringFunction<OUT> This is the single (non-parallel) task which takes a FileInputFormat and is responsible for i) monitoring a user-provided path, ii) deciding which files should be further read and processed, iii) creating the FileInputSplits corresponding to those files, and iv) assigning them to downstream tasks for further reading and processing.
class	FileMonitoringFunction Deprecated.
class	FromElementsFunction<T> A stream source function that returns a sequence of elements.
class	FromIteratorFunction<T>
class	FromSplittableIteratorFunction<T>
class	InputFormatSourceFunction<OUT>
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.
class	StatefulSequenceSource A stateful streaming source that emits each number from a given interval exactly once, possibly in parallel.
