FirstTransform

Check what the phase achieves, to be called at any point after it is finished.

A name given to the Phase that can be used to debug the compiler. For instance, it is possible to print trees after a given phase using:

$ ./bin/scalac -Xprint:<phaseNameHere> sourceFile.scala

eliminate self symbol in ClassInfo

Eliminate self in Template Under captureChecking, we keep the self type S around in a type definition

private[this] type $this = S

This is so that the type can be checked for well-formedness in the CaptureCheck phase.

If set, implicit search is enabled

Can this transform change the base types of a type?

Can this transform create or delete non-private members?

Can this transform change the parents of a class?

The sequence position of this phase in the given context where 0 is reserved for NoPhase and the first real phase is at position 1. -1 if the phase is not installed in the context.

Output should be checkable by TreeChecker

Is this phase the standard typerphase? True for TyperPhase, but not for other first phases (such as FromTasty or Parser). The predicate is tested in some places that perform checks and corrections. It's different from ctx.isAfterTyper (and cheaper to test).

The last phase during which the transformed denotations are valid

If set, allow missing or superfluous arguments in applications and type applications.

If set, use relaxed typing for all phases in group

List of names of phases that should precede this phase

List of names of phases that should have finished their processing of all compilation units before this phase starts

Convert a compilation unit's tree to a string; can be overridden

Returns a string representation of the object.

The default representation is platform dependent.

The transformation method

Transform tree using all transforms of current group (including this one)

Transform single node using all transforms following the current one in this group

Transform tree using all transforms following the current one in this group

The validity period of the transformed denotations in the given context
