All Superinterfaces:

Map<String,Object>, Serializable

All Known Implementing Classes:

DmnDecisionRuleResultImpl

public interface DmnDecisionRuleResult
extends Map<String,Object>, Serializable

The result of one decision rule. This represents the output entry values of a matching decision rule. It is a mapping from the output name attribute to the output value. If no name was given the key is null.

Method Detail

getFirstEntry

<T> T getFirstEntry()

Returns the value of the first rule result entry.

Type Parameters:

T - the type of the rule result entry

Returns:

the value of the first rule result entry or null if none exists

See Also:

getFirstEntryTyped()

getFirstEntryTyped

<T extends TypedValue> T getFirstEntryTyped()

Returns the typed value of the first rule result entry.

Type Parameters:

T - the type of the rule result entry

Returns:

the typed value of the first rule result entry or null if none exists

getFirstEntry()

getSingleEntry

<T> T getSingleEntry()

Returns the value of the single entry of the decision rule result. Which asserts that the decision rule result only has one entry.

Type Parameters:

T - the type of the rule result entry

Returns:

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

Throws:

DmnEngineException - if more than one rule result entry exists

See Also:

getSingleEntryTyped()

getSingleEntryTyped

<T extends TypedValue> T getSingleEntryTyped()

Returns the typed value of the single entry of the decision rule result. Which asserts that the decision rule result only has one entry.

Type Parameters:

T - the type of the rule result entry

Returns:

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

Throws:

DmnEngineException - if more than one rule result entry exists
