  15. def resolveClassTag(pos: Global.Position, tp: Global.Type, allowMaterialization: Boolean = true): Global.Tree

    Finds in scope or materializes a ClassTag.

    Finds in scope or materializes a ClassTag. Should be used instead of ClassManifest every time compiler needs to persist an erasure.

    Once upon a time, we had an ErasureTag which was to ClassTag the same that WeakTypeTag is for TypeTag. However we found out that we don't really need this concept, so it got removed.

    pos

    Position for error reporting. Please, provide meaningful value.

    tp

    Type we're looking a ClassTag for, e.g. resolveClassTag(pos, IntTpe) will look for ClassTag[Int].

    allowMaterialization

    If true (default) then the resolver is allowed to launch materialization macros when there's no class tag in scope. If false then materialization macros are prohibited from running.

    returns

    Tree that represents an scala.reflect.ClassTag for tp if everything is okay. EmptyTree if the result contains unresolved (i.e. not spliced) type parameters and abstract type members. EmptyTree if allowMaterialization is false, and there is no class tag in scope.

  16. def resolveTypeTag(pos: Global.Position, pre: Global.Type, tp: Global.Type, concrete: Boolean, allowMaterialization: Boolean = true): Global.Tree

    Finds in scope or materializes an WeakTypeTag (if concrete is false) or a TypeTag (if concrete is true).

    Finds in scope or materializes an WeakTypeTag (if concrete is false) or a TypeTag (if concrete is true).

    pos

    Position for error reporting. Please, provide meaningful value.

    pre

    Prefix that represents a universe this type tag will be bound to. If pre is set to NoType, then any type tag in scope will do, regardless of its affiliation. If pre is set to NoType, and tag resolution involves materialization, then mkRuntimeUniverseRef will be used.

    tp

    Type we're looking a TypeTag for, e.g. resolveTypeTag(pos, mkRuntimeUniverseRef, IntTpe, false) will look for scala.reflect.runtime.universe.TypeTag[Int].

    concrete

    If true then the result must not contain unresolved (i.e. not spliced) type parameters and abstract type members. If false then the function will always succeed (abstract types will be reified as free types).

    allowMaterialization

    If true (default) then the resolver is allowed to launch materialization macros when there's no type tag in scope. If false then materialization macros are prohibited from running.

    returns

    Tree that represents a scala.reflect.TypeTag for tp if everything is okay. EmptyTree if concrete is true and the result contains unresolved (i.e. not spliced) type parameters and abstract type members. EmptyTree if allowMaterialization is false, and there is no array tag in scope.
