PairStore (TIBCO Patterns - Search Deduplication Library)

All Known Implementing Classes:

FileSystemPairStore
```
public interface PairStore
```
Interface to access a keyed storage of batches of pairs. Batches are identified by batch Id. Batch size is also available. Some implementations may need to protect against a different Deduplicator with a different batch size from corrupting the store.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`boolean`	`isStored(java.lang.String batchId, int deduplicatorBatchSize)`	Checks if the pairs of a batch have been stored yet.
`void`	`store(java.lang.String batchId, int deduplicatorBatchSize, java.util.List<Pair> pairs)`	Store a set of pairs against a batch id.

void store(java.lang.String batchId,
           int deduplicatorBatchSize,
           java.util.List<Pair> pairs)
    throws java.lang.Exception
```
    Store a set of pairs against a batch id. Any pairs previously stored against the batch id should be removed.
    
    Parameters:
    
    batchId - The batch id to store them against
    
    deduplicatorBatchSize - The batch size assigned in the Deduplicator that produced this batch.
    
    pairs - The pairs to store
    
    Throws:
    
    java.lang.Exception - if an error occurs. Deduplicators will report this exception back through the event handler.
  - isStored
```
boolean isStored(java.lang.String batchId,
                 int deduplicatorBatchSize)
          throws java.lang.Exception
```
    Checks if the pairs of a batch have been stored yet.
    
    Parameters:
    
    batchId - Identifies the batch.
    
    deduplicatorBatchSize - The batch size assigned in the Deduplicator that produced the batch.
    
    Returns:
    
    true if the pairs are stored, false otherwise.
    
    Throws:
    
    java.lang.Exception - if an error occurs.
