Methods
Apply(RuleApplication, ParseContext, TSemanticElement, TReference, bool)
Applies the given value to the provided context element
protected override void Apply(RuleApplication ruleApplication, ParseContext context, TSemanticElement contextElement, TReference propertyValue, bool initial)
Parameters
ruleApplicationRuleApplicationthe rule application which should be applied
contextParseContextthe parse context in which this operation is performed
contextElementTSemanticElementthe element to which the value should be applied
propertyValueTReferencethe value to apply
initialboolA flag indicating whether the apply was called due to initial parse
CanSynthesize(object, ParseContext, SynthesisPlan)
Determines whether the current rule can synthesize rule applications for the given semantic element

Parameters
semanticElementobjectthe semantic element
contextParseContextthe context in which the rule is synthesized
synthesisPlanSynthesisPlanthe plan of the synthesis
Returns
- bool
true, if a rule application can be synthesized, otherwise false
