and exposed as a part of scala.reflect.api.

The owner of this symbol.
The owner of this symbol. This is the symbol
that directly contains the current symbol's definition.
The NoSymbol symbol does not have an owner, and calling this method
on one causes an internal error.
The owner of the Scala root class scala.reflect.api.Mirror.RootClass
and the Scala root object scala.reflect.api.Mirror.RootPackage is NoSymbol.
Every other symbol has a chain of owners that ends in
scala.reflect.api.Mirror.RootClass.

Set when symbol has a modifier of the form private[X], NoSymbol otherwise.
Access level encoding: there are three scala flags (PRIVATE, PROTECTED, and LOCAL) which combine with value privateWithin (the "foo" in private[foo]) to define from where an entity can be accessed. The meanings are as follows:
PRIVATE access restricted to class only. PROTECTED access restricted to class and subclasses only. LOCAL can only be set in conjunction with PRIVATE or PROTECTED. Further restricts access to the same object instance.
In addition, privateWithin can be used to set a visibility barrier. When set, everything contained in the named enclosing package or class has access. It is incompatible with PRIVATE or LOCAL, but is additive with PROTECTED (i.e. if either the flags or privateWithin allow access, then it is allowed.)
The java access levels translate as follows:
java private: isPrivate && (privateWithin == NoSymbol) java package: !isPrivate && !isProtected && (privateWithin == enclosingPackage) java protected: isProtected && (privateWithin == enclosingPackage) java public: !isPrivate && !isProtected && (privateWithin == NoSymbol)

The type signature of this symbol.
The type signature of this symbol.
This method always returns signatures in the most generic way possible, even if the underlying symbol is obtained from an
instantiation of a generic type. For example, signature
of the method def map[B](f: (A) ⇒ B): List[B], which refers to the type parameter A of the declaring class List[A],
will always feature A, regardless of whether map is loaded from the List[_] or from List[Int]. To get a signature
with type parameters appropriately instantiated, one should use typeSignatureIn.

Note that every symbol is either a term or a type.
So for every symbol sym (except for NoSymbol),
either sym.isTerm is true or sym.isType is true.
