More information may be added in the future to enable more elaborate inlinine heuristics.
Some(tp)
if this InlineInfo describes a trait, and the self
parameter type of the methods in the implementation class is not
the trait itself. Example:
trait T { self: U => def f = 1 }
Generates something like:
class T$class { static def f(self: U) = 1 }
In order to inline a trat method call, the INVOKEINTERFACE is
rewritten to an INVOKESTATIC of the impl class, so we need the
self type (U) to get the right signature.
None
if the self type is the interface type, or if this
InlineInfo does not describe a trait.
True if the class cannot have subclasses: final classes, module classes, trait impl classes.
The MethodInlineInfos for the methods declared in this class. The map is indexed by the string s"$name$descriptor" (to disambiguate overloads).
Contains an warning message if an error occured when building this InlineInfo, for example if some classfile could not be found on the classpath. This warning can be reported later by the inliner.
A marker for strings that represent class internal names.
A marker for strings that represent class internal names. Ideally the type would be incompatible with String, for example by making it a value class. But that would create overhead in a Collection[InternalName].

True if the method cannot be overridden (in Scala)
True if the method is an interface method method of a trait method and has a static counterpart in the implementation class.

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

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

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
).
