Test two objects for inequality.
true if !(this == that), false otherwise.
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).
true if the receiver object is equivalent to the argument; false otherwise.
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.

ClassCastException if the receiver object is not an instance of the erasure of type T0.
Create a copy of the receiver object.
The default implementation of the clone method is platform dependent.
a copy of the receiver object.
The default reporter simply prints the stack trace of the Throwable to System.err.
the function for error reporting
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.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).
true if the argument is a reference to the receiver object; false otherwise.
The equality method for reference types. Default implementation delegates to eq.
See also equals in scala.Any.
true if the receiver object is equivalent to the argument; false otherwise.
Called by the garbage collector on the receiver object when there are no more references to the object.
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.

Creates an ExecutionContext from the given ExecutorService with the default reporter.
If it is guaranteed that none of the executed tasks are blocking, a single-threaded ExecutorService can be used to create an ExecutionContext as follows:
import java.util.concurrent.Executors val ec = ExecutionContext.fromExecutorService(Executors.newSingleThreadExecutor())

Returns the runtime class representation of the object.
a class object corresponding to the runtime type of the receiver.
The explicit global ExecutionContext. Invoke global when you want to provide the global ExecutionContext explicitly.
The default ExecutionContext implementation is backed by a work-stealing thread pool. It can be configured via the following scala.sys.SystemProperties:
scala.concurrent.context.minThreads = defaults to "1" scala.concurrent.context.numThreads = defaults to "x1" (i.e. the current number of available processors * 1) scala.concurrent.context.maxThreads = defaults to "x1" (i.e. the current number of available processors * 1) scala.concurrent.context.maxExtraThreads = defaults to "256"
The pool size of threads is then numThreads bounded by minThreads on the lower end and maxThreads on the high end.
The maxExtraThreads is the maximum number of extra threads to have at any given time to evade deadlock, see scala.concurrent.BlockContext.

The hashCode method for reference types. See hashCode in scala.Any.
the hash code value for this object.
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.
true if the receiver object is an instance of erasure of type T0; false otherwise.
Equivalent to !(this eq that).
true if the argument is not a reference to the receiver object; false otherwise.
