Representation of a transformer function that will be applied to the result set returned by the named query. Null values returned from the transformation will be filtered out.

Example usage:

• Kotlin:

  
  class MyVaultNamedQueryTransformer : VaultNamedQueryTransformer<ContractState, MyPojo> {
  
      override fun transform(state: ContractState, parameters: Map<String, Any>): MyPojo {
          return MyPojo(1)
      }
  }
  

• Java:

  
  public class MyVaultNamedQueryTransformer implements VaultNamedQueryTransformer<ContractState, MyPojo> {
  
      
      public MyPojo transform(ContractState state, Map<String, Object> parameters) {
          return new MyPojo(1);
      }
  }
