Execution Conditions

→ represents the conditions under which a processor is executed by the traverser

• every processor has exactly one defined execution condition

There are two levels of checks:

1. A list of valid AST node types for which the processor should be executed
   • used as a fast pre-check by traversers
2. A generic function that may perform more complex checks against the current processing context
