The type of the symbol name.
The type of the symbol name.
Can be either TermName
or TypeName
depending on whether this is a TermSymbol
or a TypeSymbol
.
Type name namespaces do not intersect with term name namespaces.
This fact is reflected in different types for names of TermSymbol
and TypeSymbol
.
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.

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.

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

well as the interaction between finalize

and exceptions, are all platform dependent.

Note that the result of the test is modulo Scala's erasure semantics.
Therefore the expression 1.isInstanceOf[String]

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.
