org.scalatest.matchers.DeprecatedMatchers
This class is part of the ScalaTest matchers DSL. Please see the documentation for DeprecatedShouldMatchers or DeprecatedMustMatchers for an overview of
the matchers DSL.
This class is used as the result of an implicit conversion from class Symbol, to enable symbols to be
used in have ('author ("Dickens")) syntax. The name of the implicit conversion method is
convertSymbolToHavePropertyMatcherGenerator.
Class HavePropertyMatcherGenerator's primary constructor takes a Symbol. The
apply method uses reflection to find and access a property that has the name specified by the
Symbol passed to the constructor, so it can determine if the property has the expected value
passed to apply.
If the symbol passed is 'title, for example, the apply method
will use reflection to look for a public Java field named
"title", a public method named "title", or a public method named "getTitle".
If a method, it must take no parameters. If multiple candidates are found,
the apply method will select based on the following algorithm:
| Field | Method | "get" Method | Result |
|---|---|---|---|
Throws TestFailedException, because no candidates found | |||
getTitle() | Invokes getTitle() | ||
title() | Invokes title() | ||
title() | getTitle() | Invokes title() (this can occur when BeanProperty annotation is used) | |
title | Accesses field title | ||
title | getTitle() | Invokes getTitle() | |
title | title() | Invokes title() | |

This method enables the following syntax:

This class has an apply method that will produce a HavePropertyMatcher[AnyRef, Any].
The implicit conversion method, convertSymbolToHavePropertyMatcherGenerator, will cause the
above line of code to be eventually transformed into:
book should have (convertSymbolToHavePropertyMatcherGenerator('title).apply("A Tale of Two Cities"))
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 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 typed.

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

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

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)).
the object to compare against this object for equality.
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 finalize
and non-local returns and exceptions, are all platform dependent.

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 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 requested typed.
