LeftProjection

o != arg0 is the same as !(o == (arg0)).

o == arg0 is the same as if (o eq null) arg0 eq null else o.equals(arg0).

o == arg0 is the same as o.equals(arg0).

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.

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.

This method creates and returns a copy of the receiver object .

The default implementation of the clone method is platform dependent.

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).

The equality method defined in AnyRef.@return true if the receiver object is equivalent to the argument; false otherwise. */

Returns false if Right or returns the result of the application of the given function to the Left value .

Returns None if this is a Right or if the given predicate p does not hold for the left value, otherwise, returns a Left .

This method is called by the garbage collector on the receiver object when garbage collection determines that there are no more references to the object .

The details of when and if the finalize method are invoked, as well as the interaction between finalizeand non-local returns and exceptions, are all platform dependent.

Binds the given function across Left .

Returns true if Right or returns the result of the application of the given function to the Left value .

Executes the given side-effect if this is a Left .

Returns the value from this Left or throws Predef . NoSuchElementException if this is a Right.

Returns a representation that corresponds to the dynamic class of the receiver object .

The nature of the representation is platform dependent.

Returns the value from this Left or the given argument if this is a Right .

Returns 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.

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

Note that the test result of the test is modulo Scala's erasure semantics. Therefore the expression1.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 requested typed.

Maps the function argument through Left .

o.ne(arg0) is the same as !(o.eq(arg0)).

Wakes up a single thread that is waiting on the receiver object's monitor .

Wakes up all threads that are waiting on the receiver object's monitor .

return k for a product A(x_1, . ..,x_k)

For a product A(x_1, . ..,x_k), returns x_(n+1) for 0 <= n < k

Returns the name of the field at the given index from the definition of the class .

An iterator that returns all fields of this product

By default the empty string . Implementations may override this method in order to prepend a string prefix to the result of the toString methods.

Returns a Some containing the Left value if it exists or a None if this is a Right .

Returns a Seq containing the Left value if it exists or an empty Seq if this is a Right .

Returns a string representation of the object .

The default representation is platform dependent.
