Diagnostics (Source Generator)
TickerQ ships a Roslyn source generator that validates your [TickerFunction] classes and methods. When something is misconfigured, it reports diagnostics in your IDE/build output.
This page lists the diagnostics IDs and what they mean.
TQ001 – ClassAccessibility
Class accessibility issue
The class '{0}' should be public or internal to be used with [TickerFunction]
Make the class containing [TickerFunction] methods public or internal.
TQ002 – MethodAccessibility
Method accessibility issue
The method '{0}' should be public or internal to be used with [TickerFunction]
Make the method with [TickerFunction] public or internal.
TQ003 – InvalidCronExpression
Invalid cron expression
The cron expression '{0}' in function '{1}' is invalid
Fix the cronExpression argument on [TickerFunction] to a valid 6-part expression.
TQ004 – MissingFunctionName
Missing function name
The [TickerFunction] attribute on method '{0}' in class '{1}' must specify a function name
Always provide a functionName in [TickerFunction("Name", ...)].
TQ005 – DuplicateFunctionName
Duplicate function name
The function name '{0}' is already used by another [TickerFunction] method
Ensure each [TickerFunction] has a unique functionName across your assembly.
TQ006 – MultipleConstructors
Multiple constructors detected
The class '{0}' has multiple constructors. Only the first constructor will be used for dependency injection. Consider using [TickerQConstructor] attribute to explicitly mark the preferred constructor.
Add [TickerQConstructor] to the constructor you want TickerQ to use, or reduce to a single constructor.
TQ007 – AbstractClass
Abstract class with TickerFunction
The abstract class '{0}' contains [TickerFunction] methods
Move [TickerFunction] methods to a non-abstract class that can be instantiated.
TQ008 – NestedClass
Nested class with TickerFunction
The nested class '{0}' contains [TickerFunction] methods. TickerFunction methods are only allowed in top-level classes.
Move job handler classes to top level; nested classes are not supported for [TickerFunction].
TQ009 – InvalidMethodParameter
Invalid TickerFunction parameter
The method '{0}' has invalid parameter '{1}' of type '{2}'. TickerFunction methods can only have TickerFunctionContext, TickerFunctionContext<T>, CancellationToken parameters, or no parameters.
Update the method signature so it only uses allowed parameter types:
TickerFunctionContextTickerFunctionContext<T>CancellationToken
TQ010 – MultipleTickerQConstructorAttributes
Multiple TickerQConstructor attributes
The class '{0}' has multiple constructors with [TickerQConstructor] attribute. Only one constructor can be marked with [TickerQConstructor].
Remove extra [TickerQConstructor] attributes so at most one constructor is marked.
