The modifiers of this symbol
A list of annotations attached to this Symbol.

Note if symbol is a member of a class, one almost always is interested
in asTypeIn
with a site type instead.

The name of the symbol before decoding, e.

Whether this symbol has a "privateWithin" visibility barrier attached.
Does this symbol have given modifier?

The info of the symbol.
The info of the symbol. This is like tpe, except for class symbols where the info
describes the contents of the class whereas the tpe
is a reference to the class.
If symbol is an object definition, its implied associated class, otherwise NoSymbol
The name of the symbol as a member of the Name
type.
A fresh symbol with given name name
, position pos
and flags flags
that has
the current symbol as its owner.
The owner of this symbol.
Set when symbol has a modifier of the form private[X], NoSymbol otherwise.
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: hasFlag(PRIVATE) && !hasAccessBoundary java package: !hasFlag(PRIVATE | PROTECTED) && (privateWithin == enclosing package) java protected: hasFlag(PROTECTED) && (privateWithin == enclosing package) java public: !hasFlag(PRIVATE | PROTECTED) && !hasAccessBoundary

is the current class.
The top-level class containing this symbol.
The type of the symbol
If this symbol is a class or trait, its self type, otherwise the type of the symbol itself
The type signature of this symbol.
The type signature of this symbol.

if !(this == that), false otherwise.
Equivalent to x.hashCode

.
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.
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

Tests whether the argument (arg0

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.
The equality method for reference types.
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.

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.
