Classes in org.apache.flink.api.common.functions used by org.apache.flink.api.common.functions

Class and Description
AbstractRichFunction An abstract stub implementation for rich user-defined functions.
AggregateFunction The AggregateFunction is a flexible aggregation function, characterized by the following features: The aggregates may use different types for input values, intermediate aggregates, and result type, to support a wide range of aggregation types. Support for distributive aggregations: Different intermediate aggregates can be merged together, to allow for pre-aggregation/final-aggregation optimizations.
BroadcastVariableInitializer A broadcast variable initializer can be used to transform a broadcast variable into another format during initialization.
CoGroupFunction The interface for CoGroup functions.
CrossFunction Interface for Cross functions.
FilterFunction A filter function is a predicate applied individually to each record.
FlatJoinFunction Interface for Join functions.
FlatMapFunction Base interface for flatMap functions.
FoldFunction Deprecated. use AggregateFunction instead
Function The base interface for all user-defined functions.
GroupCombineFunction Generic interface used for combine functions ("combiners").
GroupReduceFunction The interface for group reduce functions.
IterationRuntimeContext A specialization of the RuntimeContext available in iterative computations of the DataSet API.
JoinFunction Interface for Join functions.
MapFunction Base interface for Map functions.
MapPartitionFunction Interface for "mapPartition" functions.
ReduceFunction Base interface for Reduce functions.
RichFunction An base interface for all rich user-defined functions.
RuntimeContext A RuntimeContext contains information about the context in which functions are executed.
