with default arguments. Defaults are added as named arguments calling the corresponding default getter.Example: given def foo(x: Int = 2, y: String = "def") foo(y = "lt") the argument list (y = "lt") is transformed to (y = "lt", x = foo$default$1())

asInstanceOf[T0]: T0
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 aClassCastException
at runtime, while the expressionList(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.- returns
the receiver object.

eq(arg0: AnyRef): Boolean
Tests whether the argument (
that
) 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
otherwise.

Transform a function application into a Block, and assigns typer.context .namedApplyBlockInfo to the new block as side-effect.
Transform a function application into a Block, and assigns typer.context .namedApplyBlockInfo to the new block as side-effect. If tree has the form Apply(fun, args) first the function "fun" (which might be an application itself!) is transformed into a block of the form { val qual$1 = qualifier_of_fun val x$1 = arg_1_of_fun ... val x$n = arg_n_of_fun qual$1.fun[targs](x$1, ...)...(..., x$n) } then for each argument in args, a value is created and entered into the block. finally the application expression of the block is updated. { val qual$1 = .. ... val x$n = ... > val qual$n+1 = arg(1) > ... > val qual$n+m = arg(m) > qual$1.fun[targs](x$1, ...)...(..., x$n)(x$n+1, ..., x$n+m) }
- typer

- mode

- pt

- returns
the transformed application (a Block) together with the NamedApplyInfo. if isNamedApplyBlock(tree), returns the existing context.namedApplyBlockInfo
