ClosureRefPass

The AstCreator adds closureBindingIds and ClosureBindings for captured locals, but does not add the required REF edges from the ClosureBinding to the captured node since the captured node may be a Local that is created by the LocalCreationPass and does not exist during AST creation.

This pass attempts to find the captured node in the method containing the MethodRef to the closure method, since that is the scope in which the closure would have originally been created.

WARNING: runOnPart is executed in parallel to committing of graph modifications. The upshot is that it is unsafe to read ANY data from cpg, on pain of bad race conditions

Only use ConcurrentWriterCpgPass if you are very sure that you avoid races.

E.g. adding a CFG edge to node X races with reading an AST edge of node X.

Name of the pass. By default it is inferred from the name of the class, override if needed.

Runs the cpg pass, adding changes to the passed builder. Use with caution -- API is unstable. Returns max(nParts, 1), where nParts is either the number of parallel parts, or the number of iterarator elements in case of legacy passes. Includes init() and finish() logic.

Wraps runWithBuilder with logging, and swallows raised exceptions. Use with caution -- API is unstable. A return value of -1 indicates failure, otherwise the return value of runWithBuilder is passed through.
