ExplicitOuter

Can this transform create or delete non-private members?

Denotations with a symbol where infoMayChange is false are guaranteed to be unaffected by this transform, so transformInfo need not be run. This can save time, and more importantly, can help avoid forcing symbol completers.

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

Add outer accessors if a class always needs an outer pointer

First, add outer accessors if a class does not have them yet and it references an outer this. If the class has outer accessors, implement them. Furthermore, if a parent trait might have an outer accessor, provide an implementation for the outer accessor by computing the parent's outer from the parent type prefix. If the trait ends up not having an outer accessor after all, the implementation is redundant, but does not harm. The same logic is not done for non-trait parent classes because for them the outer pointer is passed in the super constructor, which will be implemented later in a separate phase which needs to run after erasure. However, we make sure here that the super class constructor is indeed a New, and not just a type.

If set, implicit search is enabled

Do not run if compile progress has been cancelled

Can this transform change the base types of a type?

Can this transform change the parents of a class?

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

True for all phases except NoPhase

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

This property is queried when phases are first assembled. If it is false, the phase will be dropped from the set of phases to traverse.

This property is queried before a phase is run. If it is false, the phase is skipped.

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

Cancellable region, if not cancelled, run the body in the context of the current compilation unit. Enrich crash messages.

A hook that allows to transform the usual context passed to the function that prints a compilation unit after a phase

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

If set, use relaxed typing for all phases in group

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

skip the phase for a Java compilation unit, may depend on -Yjava-tasty

for purposes of progress tracking, overridden in TyperPhase

Returns a string representation of the object.

The default representation is platform dependent.
