public Interface PartitionAnalyzer

Known Direct Implementers
javax.batch.api.partition.AbstractPartitionAnalyzer
Imports
java.io.Serializable, javax.batch.runtime.BatchStatus
PartitionAnalyzer receives control to process data and final results from each partition. If a PartitionCollector is configured on the step, the PartitionAnalyzer receives control to process the data and results from the partition collector. While a separate PartitionCollector instance is invoked on each thread processing a step partition, a single PartitionAnalyzer instance runs on a single, consistent thread each time it is invoked.
