Description copied from interface: WorkItemExpressionResolver

Resolve an edoras one backend expression to a boolean value.

Specified by:

resolveBooleanExpression in interface WorkItemExpressionResolver

Parameters:

expression - the expression

workObject - the work object to resolve it on

context - additional evaluation context (a map of key/value pairs)

defaultValue - the default value returned if the passed expression is empty

Returns:

the boolean value of the expression

resolveStringExpression

public String resolveStringExpression(String expression,
                                      AnyWorkObject workObject,

Description copied from interface: WorkItemExpressionResolver

Resolve an edoras one backend expression to a String value.

Specified by:

resolveStringExpression in interface WorkItemExpressionResolver

Parameters:

expression - the expression

workObject - the work object to resolve it on

context - additional evaluation context (a map of key/value pairs)

defaultValue - the default value returned if the passed expression is empty

Returns:

the String value of the expression

resolveExpression

public Object resolveExpression(String expression,
                                AnyWorkObject workObject,
                                Map<String,Object> context,

Description copied from interface: WorkItemExpressionResolver

Resolve an edoras one backend expression to an Object value.

Specified by:

resolveExpression in interface WorkItemExpressionResolver

Parameters:

expression - the expression

workObject - the work object to resolve it on

context - additional evaluation context (a map of key/value pairs)

defaultValue - the default value returned if the passed expression is empty

Returns:

the Object value of the expression

getEvaluationContext

public AnyWorkObject getEvaluationContext(PlanItem planItem,
                                          TransitionData transitionData)

Description copied from interface: WorkItemExpressionResolver

Determine the work object for expression evaluation given the passed plan item and transition data.

Specified by:

getEvaluationContext in interface WorkItemExpressionResolver

Parameters:

planItem - the plan item.

transitionData - transition date.

Returns:

the plan item’s work object or, if there is none, the first work object instance encountered when navigating the up the plan item’s parent chain.
