Package com.orchestranetworks.addon.daqa.crosswalk Description

Provides classes and interfaces required for crosswalk operations.

CrosswalkOperationsFactory

• Gets CrosswalkOperations and calls a crosswalk operation. For example:

          AdaptationTable sourceTable = ...;
          TableContext context = new TableContext(sourceTable, procedureContext);
          CrosswalkOperations operations = CrosswalkOperationsFactory.getCrosswalkOperations();
          CrosswalkExecutionResult crosswalkResult = operations
                  .executeCrosswalk(context, new ArrayList<AdaptationTable>());
  
          RequestResult result = crosswalkResult.getCrosswalkResults();
          try
          {
                  Adaptation record;
                  while ((record = result.nextAdaptation()) != null)
                  {
                          String crosswalkPolicy = record
                                  .getString(CrosswalkResultPaths._Crosswalk._CrosswalkMatchingPolicy);
                  }
  
          }
          finally
          {
                  result.close();
          }
          
  

CrosswalkOperations

• Provides operations for Crosswalk. For example:

  Example 1:

          AdaptationTable sourceTable = ...;
          TableContext context = new TableContext(sourceTable, procedureContext);
          
          AdaptationFilter sourceFilterClass = ...;
          List<String> targetDataspaces = new ArrayList<String>();
          List<String> targetDatasets = new ArrayList<String>(
                  Arrays.asList("Crosswalk1", "Crosswalk2"));
                  
          CrosswalkContext crosswalkContext = new CrosswalkContext(
                  null,
                  sourceFilterClass,
                  targetDataspaces,
                  targetDatasets);
          
          CrosswalkOperations operations = CrosswalkOperationsFactory.getCrosswalkOperations();
          CrosswalkExecutionResult crosswalkResult = operations
                  .executeCrosswalk(context, crosswalkContext);
  
          RequestResult result = crosswalkResult.getCrosswalkResults();
          try
          {
                  Adaptation record;
                  while ((record = result.nextAdaptation()) != null)
                  {
                          BigDecimal firstScore = (BigDecimal) record
                                  .get(CrosswalkResultPaths._Crosswalk._MatchingDetail01_Score);
                  }
  
          }
          finally
          {
                  result.close();
          }
          
  

  Example 2:

          AdaptationTable sourceTable = ...;
          TableContext context = new TableContext(sourceTable, procedureContext);
          //Do not write the result into Crosswalk table.
          tableContext.setCrosswalkResultPersistenceActivated(false);
          
          CrosswalkOperations operations = CrosswalkOperationsFactory.getCrosswalkOperations();
          CrosswalkExecutionResult crosswalkResult = operations
                  .executeCrosswalk(tableContext, new ArrayList<AdaptationTable>());
                  
          RequestResult result = sourceTable.createRequestResult(null);
          try
          {
                  Adaptation record;
                  while ((record = result.nextAdaptation()) != null)
                  {
                          List<CrosswalkTableResult> tableResults = crosswalkResult
                                  .getResults(record.getOccurrencePrimaryKey());
                          for (CrosswalkTableResult tableResult : tableResults)
                          {
                                  List<CrosswalkRecordResult> recordResults = tableResult.getResults();
                                  for (CrosswalkRecordResult recordResult : recordResults)
                                  {
                                          //do something
                                  }
                          }
                  }
          }
          finally
          {
                  result.close();
          }
