The position type of this attachment
The position indicates a column and the line in the source file.
The end of the position's range, error if not a range position.
The end of the position's range, or point if not a range position.
If this is a range position, the offset position of its point.

Does this position include the given position pos?
This holds if this is a range position and its range [start.
Does this position include the given position pos?
This holds if this is a range position and its range [start..end]
is the same or covers the range of the given position, which may or may not be a range position.
Is this position neither a NoPosition nor a FakePosition? If isDefined is true, offset and source are both defined.
Is this position a non-transparent range position?
Is this position a range position?
Is this position a transparent position?
The position indicates a column and the line in the source file.
The content of the line this Position refers to.
If opaque range, make this position transparent.
Does this position overlap with that position? This holds if both positions are ranges and there is an interval of non-zero length that is shared by both position ranges.
The point (where the ^ is) of the position, which is easiest to access using the line and column values. The line content is also available.
The point (where the ^ is) of the position, or else default if undefined.
The underlying position
The underlying position
Does this position precede that position? This holds if both positions are defined and the end point of this position is not larger than the start point of the given position.
Does this position properly include the given position pos ("properly" meaning their
ranges are not the same)?
Does this position properly precede the given position pos ("properly" meaning their ranges
do not share a common point).
Does this position cover the same range as that position? Holds only if both position are ranges
Show a textual representation of the position.

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.
The start of the position's range, error if not a range position.
The start of the position's range, or point if not a range position.
Convert this to a position around point that spans a single source line
If this is a range, the union with the other range, with the point of this position.
If this is a range, the union with the other range, with the point of this position. Otherwise, this position
The same position with a different end value (if a range).
The same position with a different point value (if a range or offset).

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.

Test two objects for equality.
The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).
true if the receiver object is equivalent to the argument; false otherwise.

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.

Create a copy of the receiver object.
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).
true if the argument is a reference to the receiver object; false otherwise.

Called by the garbage collector on the receiver object when there are no more references to the object.

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.

Format strings are as for String.format

The hashCode method for reference types.
Test whether the dynamic type of the receiver object is T0.
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.
true if the receiver object is an instance of erasure of type T0; false otherwise.

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.
Please note that this trait may be refactored in future versions of the Scala reflection API.
