class CoreBTypes[BTFS <: BTypesFromSymbols[_ <: Global]] extends AnyRef
Core BTypes and some other definitions. The initialization of these definitions requires access to symbols / types (global).
The symbols used to initialize the ClassBTypes may change from one compiler run to the next. To
make sure the definitions are consistent with the symbols in the current run, the
intializeCoreBTypes
method in BTypesFromSymbols creates a new instance of CoreBTypes in each
compiler run.
The class BTypesFromSymbols does not directly reference CoreBTypes, but CoreBTypesProxy. The
reason is that having a var bTypes: CoreBTypes
would not allow import bTypes._
. Instead, the
proxy class holds a CoreBTypes
in a variable field and forwards to this instance.
The definitions in CoreBTypes
need to be lazy vals to break an initialization cycle. When
creating a new instance to assign to the proxy, the classBTypeFromSymbol
invoked in the
constructor will actually go through the proxy. The lazy vals make sure the instance is assigned
in the proxy before the fields are initialized.
Note: if we did not re-create the core BTypes on each compiler run, BType.classBTypeFromInternalNameMap could not be a perRunCache anymore: the classes defined here need to be in that map, they are added when the ClassBTypes are created. The per run cache removes them, so they would be missing in the second run.

eq(arg0: AnyRef): Boolean
Tests whether the argument (

) is a reference to the receiver object (this
).Tests whether the argument (
that
) is a reference to the receiver object (this
).The
eq
method implements an equivalence relation on non-null instances ofAnyRef
, and has three additional properties:- It is consistent: for any non-null instances
x
andy
of typeAnyRef
, multiple invocations ofx.eq(y)
consistently returnstrue
or consistently returnsfalse
. - For any non-null instance
x
of typeAnyRef
,x.eq(null)
andnull.eq(x)
returnsfalse
. null.eq(null)
returnstrue
.
When overriding the
equals
orhashCode
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
).- returns
true
if the argument is a reference to the receiver object;false
