false if the receiver object is equivalent to the argument; true otherwise.
This method enables the following syntax:
This method enables the following syntax:
result should be < (7)
Note that the less than operator will be invoked on be in this expression, not
on a result of passing be to should, as with most other operators
in the matchers DSL, because the less than operator has a higher precedence than should.
Thus in the above case the first expression evaluated will be be < (7), which results
in a matcher that is passed to should.
This method also enables the following syntax:
result should not (be < (7))
This method enables the following syntax:
This method enables the following syntax:
result should be <= (7)
Note that the less than or equal to operator will be invoked on be in this expression, not
on a result of passing be to should, as with most other operators
in the matchers DSL, because the less than or equal to operator has a higher precedence than should.
Thus in the above case the first expression evaluated will be be <= (7), which results
in a matcher that is passed to should.

This method enables the following syntax:
result should be === (7)
Note that the === operator will be invoked on be in this expression, not
on a result of passing be to should, as with most other operators
in the matchers DSL, because the ===n operator has a higher precedence than should.
Thus in the above case the first expression evaluated will be be === (7), which results
in a matcher that is passed to should.
This method also enables the following syntax:

This method enables the following syntax:
result should be > (7)
Note that the greater than operator will be invoked on be in this expression, not
on a result of passing be to should, as with most other operators

Thus in the above case the first expression evaluated will be be > (7), which results
in a matcher that is passed to should.
This method also enables the following syntax:

This method enables the following syntax:
This method enables the following syntax:

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.

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).

true if the argument is a reference to the receiver object; false otherwise.
This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.
This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.
The default implementations of this method is an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence
relation]:
* It is reflexive: for any instance x of type Any, x.equals(x) should return true.
* It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and
only if y.equals(x) returns true.
* It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and
y.equals(z) returns true, then x.equals(z) should return true.
If you override this method, you should verify that your implementation remains an equivalence relation.
Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects
that are "equal" (o1.equals(o2) returns true) hash to the same
scala.Int
(o1.hashCode.equals(o2.hashCode)).

true if the receiver object is equivalent to the argument; false otherwise.
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.
Returns a representation that corresponds to the dynamic class of the receiver object.

Returns a hash code value for the object.
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.
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.

BeWordcontains anapplymethod that takes aSymbol, which uses reflection to find and access aBooleanproperty and determine if it istrue. If the symbol passed is'empty, for example, theapplymethod will use reflection to look for a public Java field named "empty", a public method named "empty", or a public method named "isEmpty". If a field, it must be of typeBoolean. If a method, it must take no parameters and returnBoolean. If multiple candidates are found, theapplymethod will select based on the following algorithm:TestFailedException, because no candidates foundisEmpty()isEmpty()empty()empty()empty()isEmpty()empty()(this can occur whenBeanPropertyannotation is used)emptyemptyemptyisEmpty()isEmpty()emptyempty()empty()emptyempty()isEmpty()empty()(this can occur whenBeanPropertyannotation is used)
