Interface DmnDecisionResult

All Superinterfaces:

Collection<DmnDecisionResultEntries>, Iterable<DmnDecisionResultEntries>, List<DmnDecisionResultEntries>, Serializable

All Known Implementing Classes:

DmnDecisionResultImpl

public interface DmnDecisionResult
extends List<DmnDecisionResultEntries>, Serializable

The result of one decision evaluation. It can be composed of multiple DmnDecisionResultEntriess which represents the output entries (i.e., pairs of output name and value).

In case of a decision with a decision table, the result has one DmnDecisionResultEntries for each matched rule that contains the output entries of this rule.

Method Summary

<T> List<T>	collectEntries(String outputName)	Collects the entries for a output name.
DmnDecisionResultEntries	getFirstResult()	Returns the first DmnDecisionResultEntries.
List<Map<String,Object>>	getResultList()	Returns the entries of all decision results.
<T> T	getSingleEntry()	Returns the value of the single entry of the decision result.
<T extends TypedValue> T	getSingleEntryTyped()	Returns the typed value of the single entry of the decision result.
DmnDecisionResultEntries	getSingleResult()	Returns the single DmnDecisionResultEntries of the result.

Method Detail

getFirstResult

DmnDecisionResultEntries getFirstResult()

Returns the first DmnDecisionResultEntries.

Returns:

the first decision result or null if none exits

getSingleResult

DmnDecisionResultEntries getSingleResult()

Returns the single DmnDecisionResultEntries of the result. Asserts that only one decision result exist.

Returns:

the single decision result or null if none exists

Throws:

DmnEngineException - if more than one decision result exists

collectEntries

<T> List<T> collectEntries(String outputName)

Collects the entries for a output name. The list will contain entries for the output name of every DmnDecisionResultEntries. Note that the list may contains less entries than decision results if an output does not contain a value for the output name.

Type Parameters:

T - the type of the result entry

Parameters:

outputName - the name of the output to collect

Returns:

the list of collected output values

getResultList

List<Map<String,Object>> getResultList()

Returns the entries of all decision results. For every decision result a map of the output names and corresponding entries is returned.

Returns:

the list of all entry maps

DmnDecisionResultEntries.getEntryMap()

getSingleEntry

<T> T getSingleEntry()

Returns the value of the single entry of the decision result. Asserts that only one decision result with a single entry exist.

Type Parameters:

T - the type of the result entry

Returns:

the value of the single result entry or null if none exists

Throws:

DmnEngineException - if more than one decision result or more than one result entry exists

See Also:

getSingleEntryTyped()

getSingleEntryTyped

<T extends TypedValue> T getSingleEntryTyped()

Returns the typed value of the single entry of the decision result. Asserts that only one decision result with a single entry exist.

Type Parameters:

T - the type of the result entry

Returns:

the typed value of the single result entry or null if none exists

Throws:

DmnEngineException - if more than one decision result or more than one result entry exists
