Test two objects for inequality.
Test two objects for inequality.
true if !(this == that), false otherwise.
Equivalent to x.hashCode except for boxed numeric types and null.
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.
a hash value consistent with ==
The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).
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.
Generate exception handlers for the body.
Generate exception handlers for the body. Body is evaluated with a context where all the handlers are active. Handlers are evaluated in the 'outer' context.
It returns the resulting context, with the same active handlers as before the call. Use it like:
ctx.Try( ctx => {
ctx.bb.emit(...) // protected block
}, (ThrowableClass,
ctx => {
ctx.bb.emit(...); // exception handler
}), (AnotherExceptionClass,
ctx => {...
} ))
The resulting structure will look something like
outer: // this 'useless' jump will be removed later, // for now it separates the try body's blocks from previous // code since the try body needs its own exception handlers JUMP body
body: [ try body ] JUMP normalExit
catch[i]: [ handler[i] body ] JUMP normalExit
catchAll: STORE exception [ finally body ] THROW exception
normalExit: [ finally body ]
each catch[i] will cover body. catchAll will cover both body and each catch[i] Additional finally copies are created on the emission of every RETURN in the try body and exception handlers.
This could result in unreachable code which has to be cleaned up later, e.g. if the try and all the exception handlers always end in RETURN then there will be no "normal" flow out of the try/catch/finally. Later reachability analysis will remove unreachable code.
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 (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 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 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.

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.
