Type Parameters:

INDIVIDUAL_DECISION_REQUEST - type of individual decision request.

OUTPUT_DECISION_RESPONSE - type of output decision response. Usually serializable, e.g. XACML-schema-derived JAXB Result for XML.

All Known Implementing Classes:

BaseXacmlJaxbResultPostprocessor
```
public interface DecisionResultPostprocessor<INDIVIDUAL_DECISION_REQUEST extends DecisionRequest,OUTPUT_DECISION_RESPONSE>
```
XACML Decision Result post-processor, i.e. a PDP extension that processes decision Results after policy evaluation. Each Result corresponds to an Individual Decision Request. Besides, a typical Result post-processor may combine multiple individual decision results into a single decision Result if and only if the XACML Request's 'CombinedDecision' is set to true, as defined in XACML Multiple Decision Profile specification, section 3.
Note: this interface is meant to be generic enough to be independent of the Result data serialization format (XML, JSON...).

- Method Detail
  - getRequestType
```
Class<INDIVIDUAL_DECISION_REQUEST> getRequestType()
```
    Gets the class of supported individual decision request objects
    
    Returns:
    
    (individual decision) request type parameter
  - getResponseType
```
Class<OUTPUT_DECISION_RESPONSE> getResponseType()
```
    Gets the class of output decision response
    
    Returns:
    
    result type parameter
  - getFeatures
```
default Set<String> getFeatures()
```
    Get supported features, e.g. "urn:oasis:names:tc:xacml:3.0:profile:multiple:combined-decision" for Combined Decision
    
    Returns:
    
    list of identifiers of supported features
  - process
```
OUTPUT_DECISION_RESPONSE process(Collection<Map.Entry<INDIVIDUAL_DECISION_REQUEST,? extends DecisionResult>> resultsByRequest)
```
    Process multiple individual decision results (e.g. combine them if CombinedDecision=true)
    
    Parameters:
    
    resultsByRequest - results mapped to corresponding individual decision requests for correlation
    
    Returns:
    
    output response
  - processClientError
```
OUTPUT_DECISION_RESPONSE processClientError(IndeterminateEvaluationException error)
```
    Process an indeterminate result, i.e. evaluation error, in case of client request error.
    
    Parameters:
    
    error - client request error
    
    Returns:
    
    error result
  - processInternalError
```
OUTPUT_DECISION_RESPONSE processInternalError(IndeterminateEvaluationException error)
```
    Process an indeterminate result, i.e. evaluation error, in case of PDP engine's internal error, as opposed to client request errors.
    For security reasons, error details should not be included in this case as they may disclose PDP internal issues (e.g. bad configuration) to clients.
    
    Parameters:
    
    error - internal error
    
    Returns:
    
    error Result
