final def ##(): Int

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.
returns
a hash value consistent with ==

If the ACC_INTERFACE flag is set, the ACC_ABSTRACT flag must also be set (ch. 2.13.1).
A class file cannot have both its ACC_FINAL and ACC_ABSTRACT flags set (ch. 2.8.2).
A field may have at most one of its ACC_PRIVATE, ACC_PROTECTED, ACC_PUBLIC flags set (ch. 2.7.4).
A field may not have both its ACC_FINAL and ACC_VOLATILE flags set (ch. 2.9.1).
If a method has its ACC_ABSTRACT flag set it must not have any of its ACC_FINAL, ACC_NATIVE, ACC_PRIVATE, ACC_STATIC, ACC_STRICT, or ACC_SYNCHRONIZED flags set (ch. 2.13.3.2).
All interface methods must have their ACC_ABSTRACT and ACC_PUBLIC flags set.

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.

final def eq(arg0: AnyRef): Boolean

Tests whether the argument (arg0) is a reference to the receiver object (this).
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:
- It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
- For any non-null instance 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).
returns
true if the argument is a reference to the receiver object; false otherwise.
