The return type is scala.reflect.io.AbstractFile, which belongs to an experimental part of Scala reflection.
It should not be used unless you know what you are doing. In subsequent releases, this API will be refined
and exposed as a part of scala.reflect.api.

true if !(this == that), false otherwise.
Equivalent to x.hashCode except for boxed numeric types and null.
Equivalent to x.hashCode except for boxed numeric types and null.
For numerics, it returns a hash value which is consistent
with value equality: if two value type instances compare
as true, then ## will produce the same hash value for each
of them.
For null returns a hashcode where null.hashCode throws a
NullPointerException.

The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).

Cast the receiver object to be of type T0.
Cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics.
Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at
runtime, while the expression List(1).asInstanceOf[List[String]] will not.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the requested type.

Tests whether the argument (arg0) is a reference to the receiver object (this).
Tests whether the argument (arg0) is a reference to the receiver object (this).
The eq method implements an equivalence relation on
non-null instances of AnyRef, and has three additional properties:
x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.x of type AnyRef, x.eq(null) and null.eq(x) returns false.null.eq(null) returns true. When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

The details of when and if the finalize method is invoked, as
well as the interaction between finalize and non-local returns
and exceptions, are all platform dependent.

Test whether the dynamic type of the receiver object is T0.
Note that the result of the test is modulo Scala's erasure semantics.
Therefore the expression 1.isInstanceOf[String] will return false, while the
expression List(1).isInstanceOf[List[String]] will return true.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the specified type.

Position tracks the origin of symbols and tree nodes. They are commonly used when displaying warnings and errors, to indicate the incorrect point in the program.
A position indicates the source file and an offset. A position may be undefined, which means it's pointing to the Positions#NoPosition element.
Please note that this trait may be refactored in future versions of the Scala reflection API.
http://docs.scala-lang.org/overviews/reflection/names-exprs-scopes-more.html
The compiler adds more information to positions, such a ranges in the source file and defines different types of positions depending on how a symbol or tree node was generated. The guide fully describes compiler-generated positions.
The following tests are useful on positions:
pos.isDefinedtrue if position is not a NoPosition,pos.isRangetrue if position is a range,pos.isOpaqueRangetrue if position is an opaque range,There are also convenience methods, such as
pos.startOrPoint,pos.endOrPoint,pos.pointOrElse(default). These are less strict about the kind of position on which they can be applied.The following conversion methods are often used:
pos.focusconverts a range position to an offset position, keeping its point; returns all other positions unchanged,pos.makeTransparentconverts an opaque range position into a transparent one. returns all other positions unchanged.
