Is this context in all modes in the given mask?

A bitmask containing all the boolean flags in a context, e.g. are implicit views enabled

The next outer context whose tree is a template or package definition

The next enclosing context (potentially this) that is owned by a class or method

The next (logical) outer context whose tree is a method.

NOTE: this is the "logical" enclosing method, which may not be the actual enclosing method when we synthesize a nested method, such as for lazy val getters (scala/bug#8245) or the methods that implement a PartialFunction literal (scala/bug#10291).

...or an Apply.

The next enclosing context (potentially this) that has a CaseDef as a tree

Return the closest enclosing context that defines a subclass of clazz or a companion object thereof, or NoContext if no such context exists.

Issue/throw the given error message according to the current mode for error reporting.

Return and clear the undetermined type parameters

Equivalent to imports.headOption, but more efficient

The currently visible imports

Use reporter (possibly buffered) for errors/warnings and enable implicit conversion *

Is sym accessible as a member of pre in current context?

Must sym defined in package object of package pkg, if it selected from a prefix with pkg as its type symbol?

Construct a child context. The parent and child will share the report buffer. Compare with makeSilent, in which the child has a fresh report buffer.

If tree is an Import, that import will be available at the head of Context#imports.

A context for typing constructor parameter ValDefs, super or self invocation arguments and default getters of constructors. These expressions need to be type checked in a scope outside the class, cf. spec 5.3.1.

This method is called by namer / typer where this is the context for the constructor DefDef. The owner of the resulting (new) context is the outer context for the Template, i.e. the context for the ClassDef. This means that class type parameters will be in scope. The value parameters of the current constructor are also entered into the new constructor scope. Members of the class however will not be accessible.

Make a silent child context does not allow implicits. Used to prevent chaining of implicit views.

Make a child context that represents a new nested scope

Make a child context that buffers errors and warnings into a fresh report buffer.

Types for which implicit arguments are currently searched

Saved type bounds for type parameters which are narrowed in a GADT.

Run body with this context with no undetermined type parameters, restore the original the original list afterwards.

Set all modes in the mask enable to true, and all in disable to false.

Undetermined type parameters. See Infer#{inferExprInstance, adjustTypeArgs}. Not inherited to child contexts

Update all modes in mask to value

Issue/throw the given error message according to the current mode for error reporting.

TypeConstructorAllowed is enabled when we are typing a higher-kinded type. adapt should then check kind-arity based on the prototypical type's kind arity. Type arguments should not be inferred.
