Members list

Value members

Abstract methods

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

Attributes

Concrete methods

If set, implicit search is enabled

Attributes

Do not run if compile progress has been cancelled

Attributes

Can this transform change the base types of a type?

Attributes

Can this transform create or delete non-private members?

Attributes

Can this transform change the parents of a class?

Attributes

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

Attributes

True for all phases except NoPhase

Attributes

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.

Attributes

Output should be checkable by TreeChecker

Attributes

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.

Attributes

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

Attributes

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).

Attributes

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

Attributes

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

Attributes

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

Attributes

List of names of phases that should precede this phase

Attributes

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

Attributes

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

Attributes

for purposes of progress tracking, overridden in TyperPhase

Attributes

Returns a string representation of the object.

The default representation is platform dependent.

Attributes

Returns: a string representation of the object.
