    Selectively activate this analyzer plugin, e.g.

    Selectively activate this analyzer plugin, e.g. according to the compiler phase.

    Note that the current phase can differ from the global compiler phase (look for enteringPhase invocations in the compiler). For instance, lazy types created by the UnPickler are completed at the phase in which their symbol is created. Observations show that this can even be the parser phase. Since symbol completion can trigger subtyping, typing etc, your plugin might need to be active also in phases other than namer and typer.

    Typically, this method can be implemented as

    global.phase.id < global.currentRun.picklerPhase.id

27.  def pluginsPt(pt: Global.Type, typer: Analyzer.Typer, tree: Global.Tree, mode: Mode): Global.Type

    Let analyzer plugins change the expected type before type checking a tree.

28.  def pluginsTypeSig(tpe: Global.Type, typer: Analyzer.Typer, defTree: Global.Tree, pt: Global.Type): Global.Type

    Let analyzer plugins change the types assigned to definitions.

    Let analyzer plugins change the types assigned to definitions. For definitions that have an annotated type, the assigned type is obtained by typing that type tree. Otherwise, the type is inferred by typing the definition's righthand side.

    In order to know if the type was inferred, you can query the wasEmpty field in the tpt TypeTree of the definition (for DefDef and ValDef).

    (*) If the type of a method or value is inferred, the type-checked tree is stored in the analyzer.transformed hash map, indexed by the definition's rhs tree.

    NOTE: Invoking the type checker can lead to cyclic reference errors. For instance, if this method is called from the type completer of a recursive method, type checking the method rhs will invoke the same completer again. It might be possible to avoid this situation by assigning tpe to defTree.symbol (untested) - the final type computed by this method will then be assigned to the definition's symbol by monoTypeCompleter (in Namers).

    The hooks into typeSig allow analyzer plugins to add annotations to (or change the types of) definition symbols. This cannot not be achieved by using pluginsTyped: this method is only called during type checking, so changing the type of a symbol at this point is too late: references to the symbol might already be typed and therefore obtain the original type assigned during naming.

    defTree

    is the definition for which the type was computed. The different cases are outlined below. Note that this type is untyped (for methods and values with inferred type, the typed rhs trees are available in analyzer.transformed). Case defTree: Template

    • tpe : A ClassInfoType for the template
    • typer: The typer for template members, i.e. expressions and definitions of defTree.body
    • pt : WildcardType
    • the class symbol is accessible through typer.context.owner Case defTree: ClassDef
    • tpe : A ClassInfoType, or a PolyType(params, ClassInfoType) for polymorphic classes. The class type is the one computed by templateSig, i.e. through the above case
    • typer: The typer for the class. Note that this typer has a different context than the typer for the template.
    • pt : WildcardType Case defTree: ModuleDef
    • tpe : A ClassInfoType computed by templateSig
    • typer: The typer for the module. context.owner of this typer is the module class symbol
    • pt : WildcardType Case defTree: DefDef
    • tpe : The type of the method (MethodType, PolyType or NullaryMethodType). (*)
    • typer: The typer the rhs of this method
    • pt : If tpt.isEmpty, either the result type from the overridden method, or WildcardType. Otherwise the type obtained from typing tpt.
    • Note that for constructors, pt is the class type which the constructor creates. To type check the rhs of the constructor however, the expected type has to be WildcardType (see Typers.typedDefDef) Case defTree: ValDef
    • tpe : The type of this value. (*)
    • typer: The typer for the rhs of this value
    • pt : If tpt.isEmpty, WildcardType. Otherwise the type obtained from typing tpt.
    • Note that pluginsTypeSig might be called multiple times for the same ValDef since it is used to compute the types of the accessor methods (see pluginsTypeSigAccessor) Case defTree: TypeDef
    • tpe : The type obtained from typing rhs (PolyType if the TypeDef defines a polymorphic type)
    • typer: The typer for the rhs of this type
    • pt : WildcardType

29.  def pluginsTypeSigAccessor(tpe: Global.Type, typer: Analyzer.Typer, tree: Global.ValDef, sym: Global.Symbol): Global.Type

    Modify the types of field accessors.

    Modify the types of field accessors. The namer phase creates method types for getters and setters based on the type of the corresponding field.

    Note: in order to compute the method type of an accessor, the namer calls typeSig on the ValDef tree of the corresponding field. This implies that the pluginsTypeSig method is potentially called multiple times for the same ValDef tree.

    tpe

    The method type created by the namer for the accessor

    typer

    The typer for the ValDef (not for the rhs)

    tree

    The ValDef corresponding to the accessor

    sym

    The accessor method symbol (getter, setter, beanGetter or beanSetter)
