abstract def canEqual(that: Any): Boolean

A method that should be called from every well-designed equals method that is open to be overridden in a subclass. See Programming in Scala, Chapter 28 for discussion and design.

that: the value being probed for possible equality
returns: true if this instance can possibly equal that, otherwise false

Definition Classes: Equals

abstract def getClass(): Class[_ <: AnyRef]

Returns the runtime class representation of the object.

returns: a class object corresponding to the runtime type of the receiver.

Definition Classes: Any

Concrete Value Members

final def !=(arg0: Any): Boolean

Test two objects for inequality.

returns: true if !(this == that), false otherwise.

Definition Classes: Any

final def ##(): Int

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 ==

Implicit: This member is added by an implicit conversion from Product18[T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, T16, T17, T18] toany2stringadd[Product18[T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, T16, T17, T18]] performed by method any2stringadd in scala.Predef.

final def ==(arg0: Any): Boolean

Test two objects for equality. The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).

returns: true if the receiver object is equivalent to the argument; false otherwise.

Definition Classes: Any

final def asInstanceOf[T0]: 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.

returns: the receiver object.

Definition Classes: Any
Exceptions thrown: ClassCastException if the receiver object is not an instance of the erasure of type T0.

Definition Classes: Ensuring

def equals(arg0: Any): Boolean

Compares the receiver object (this) with the argument object (that) for equivalence.

Any implementation of this method should be an equivalence relation:

x

Any

x.equals(x)

true

x

y

Any

x.equals(y)

true

y.equals(x)

true

x

y

z

Any

x.equals(y)

true

y.equals(z)

true

x.equals(z)

true

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).

returns: true if the receiver object is equivalent to the argument; false otherwise.

Definition Classes: Any

def formatted(fmtstr: String): String

Returns string formatted according to given format string. Format strings are as for String.format (@see java.lang.String.format).

Implicit: This member is added by an implicit conversion from Product18[T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, T16, T17, T18] toStringFormat[Product18[T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, T16, T17, T18]] performed by method StringFormat in scala.Predef.
Definition Classes: StringFormat
Annotations: @inline()

def hashCode(): Int

Calculate a hash code value for the object.

The default hashing algorithm is platform dependent.

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

returns: the hash code value for this object.

Definition Classes: Any

final def isInstanceOf[T0]: Boolean

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.

returns: true if the receiver object is an instance of erasure of type T0; false otherwise.

Definition Classes: Any

def productArity: Int

The arity of this product.

returns: 18

Definition Classes: Product18 → Product

def productElement(n: Int): Any

Returns the n-th projection of this product if 0 <= n < productArity, otherwise throws an IndexOutOfBoundsException.

n: number of the projection to be returned
returns: same as ._(n+1), for example productElement(0) is the same as ._1.

Definition Classes: Product18 → Product
Annotations: @throws(classOf[IndexOutOfBoundsException])
Exceptions thrown: IndexOutOfBoundsException if the n is out of range(n < 0 || n >= 18).

def productElementName(n: Int): String

The name of the n^th element of this product, 0-based. In the default implementation, an empty string.

n: the index of the element name to return
returns: the name of the specified element

Definition Classes: Product
Exceptions thrown: IndexOutOfBoundsException if the n is out of range(n < 0 || n >= productArity).

def productElementNames: Iterator[String]

An iterator over the names of all the elements of this product.

Definition Classes: Product

def productIterator: Iterator[Any]

An iterator over all the elements of this product.

returns: in the default implementation, an Iterator[Any]

Definition Classes: Product

def productPrefix: String

A string used in the toString methods of derived classes. Implementations may override this method to prepend a string prefix to the result of toString methods.

returns: in the default implementation, the empty string

Definition Classes: Product

def toString(): String

Returns a string representation of the object.

The default representation is platform dependent.

returns: a string representation of the object.
