StackDepthException

class StackDepthException extends RuntimeException with StackDepth

Exception class that encapsulates information about the stack depth at which the line of code that failed resides, so that information can be presented to the user that makes it quick to find the failing line of code. (In other words, the user need not scan through the stack trace to find the correct filename and line number of the problem code.) Having a stack depth is more useful in a testing environment in which test failures are implemented as thrown exceptions, as is the case in ScalaTest's built-in suite traits.

  8. def asInstanceOf [T0] : T0

    This method is used to cast the receiver object to be of type T0.

    This method is used to 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 expression1.asInstanceOf[String] will throw a ClassCastException 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 typed.

    returns

    the receiver object.

  12. def eq (arg0: AnyRef) : Boolean

    This method is used to test whether the argument (arg0) is a reference to the receiver object (this).

    This method is used to test whether the argument (arg0) is a reference to the receiver object (this).

    The eq method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on non-null instances of AnyRef: * It is reflexive: for any non-null instance x of type AnyRef, x.eq(x) returns true. * It is symmetric: for any non-null instances x and y of type AnyRef, x.eq(y) returns true if and only if y.eq(x) returns true. * It is transitive: for any non-null instances x, y, and z of type AnyRef if x.eq(y) returns true and y.eq(z) returns true, then x.eq(z) returns true.

    Additionally, the eq method has three other 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).

    arg0

    the object to compare against this object for reference equality.

    returns

    true if the argument is a reference to the receiver object; false otherwise.

  13. def equals (other: Any) : Boolean

    Indicates whether this object is equal to the passed object.

    Indicates whether this object is equal to the passed object. If the passed object is a StackDepthException, equality requires equal message,cause, and failedCodeStackDepth fields, as well as equal return values of getStackTrace.@return true if the receiver object is equivalent to the argument; false otherwise. */

    This method is used to test whether the dynamic type of the receiver object is T0.
