Method Detail

open

public void open(org.apache.flink.configuration.Configuration configuration)
          throws Exception

Deprecated.

Specified by:

open in interface org.apache.flink.api.common.functions.RichFunction

Overrides:

open in class org.apache.flink.api.java.operators.translation.WrappingFunction<AllWindowFunction<ACC,R,W extends Window>>

Throws:

Exception

apply

public void apply(W window,
                  Iterable<T> values,
                  org.apache.flink.util.Collector<R> out)
           throws Exception

Deprecated.

Description copied from interface: AllWindowFunction

Evaluates the window and outputs none or several elements.

Specified by:

apply in interface AllWindowFunction<T,R,W extends Window>

Parameters:

window - The window that is being evaluated.

values - The elements in the window being evaluated.

out - A collector for emitting elements.

Throws:

Exception - The function may throw exceptions to fail the program and trigger recovery.

setOutputType

public void setOutputType(org.apache.flink.api.common.typeinfo.TypeInformation<R> outTypeInfo,
                          org.apache.flink.api.common.ExecutionConfig executionConfig)

Deprecated.

Description copied from interface: OutputTypeConfigurable

Is called by the org.apache.flink.streaming.api.graph.StreamGraph#addOperator(Integer, String, StreamOperator, TypeInformation, TypeInformation, String) method when the StreamGraph is generated. The method is called with the output TypeInformation which is also used for the StreamTask output serializer.

Specified by:

setOutputType in interface OutputTypeConfigurable<R>

Parameters:

outTypeInfo - Output type information of the StreamTask

executionConfig - Execution configuration
