Method Detail

init

public void init(ProcessorContext context)

Deprecated.

Description copied from interface: Processor

Initialize this processor with the given context. The framework ensures this is called once per processor when the topology that contains it is initialized. When the framework is done with the processor, Processor.close() will be called on it; the framework may later re-use the processor by calling #init() again.

The provided context can be used to access topology and record meta data, to schedule a method to be called periodically and to access attached StateStores.

Specified by:

init in interface Processor<K,V>

Parameters:

context - the context; may not be null

close

public void close()

Deprecated.

Close this processor and clean up any resources.

This method does nothing by default; if desired, subclasses should override it with custom functionality.

Specified by:

close in interface Processor<K,V>
