Method Detail

resolveBooleanExpression

boolean resolveBooleanExpression(String expression,
                                 AnyWorkObject workObject,
                                 Map<String,Object> context,
                                 Boolean defaultValue)

Resolve an edoras one backend expression to a boolean value.

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

String resolveStringExpression(String expression,
                               AnyWorkObject workObject,
                               Map<String,Object> context,
                               String defaultValue)

Resolve an edoras one backend expression to a String value.

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

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

Resolve an edoras one backend expression to an Object value.

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

AnyWorkObject getEvaluationContext(PlanItem planItem,
                                   TransitionData transitionData)

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

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.
