The main interface that needs to be implemented by the named ledger queries. Implementing this interface will define how the named query will be built and stored.

Example usage:

• Kotlin:

  
  class MyVaultNamedQueryFactory : VaultNamedQueryFactory {
  
      override fun create(vaultNamedQueryBuilderFactory: VaultNamedQueryBuilderFactory) {
          vaultNamedQueryBuilderFactory.create("FIND_WITH_CORDA_COLUMNS")
              .whereJson(
                  "WHERE custom ->> 'TestUtxoState.testField' = :testField " +
                          "AND custom ->> 'Corda.participants' IN :participants " +
                          "AND custom ? :contractStateType " +
                          "AND custom ->> 'Corda.createdTimestamp' > :created_timestamp"
              )
              .filter(MyVaultNamedQueryFilter())
              .map(MyVaultNamedQueryTransformer())
              .collect(MyVaultNamedQueryCollector())
              .register()
  
      }
  }
  

• Java:

  
  public class MyVaultNamedQueryFactory implements VaultNamedQueryFactory {
      
      public void create(@NotNull VaultNamedQueryBuilderFactory vaultNamedQueryBuilderFactory) {
          vaultNamedQueryBuilderFactory.create("FIND_WITH_CORDA_COLUMNS")
                  .whereJson(
                          "WHERE custom ->> 'TestUtxoState.testField' = :testField " +
                                  "AND custom ->> 'Corda.participants' IN :participants " +
                                  "AND custom ? :contractStateType " +
                                  "AND custom ->> 'Corda.createdTimestamp' > :created_timestamp"
                  )
                  .filter(new MyVaultNamedQueryFilter())
                  .map(new MyVaultNamedQueryTransformer())
                  .collect(new MyVaultNamedQueryCollector())
                  .register();
      }
  }
