/**
|
|
* Tests amount of time taken to invoke Class methods
|
|
*
|
|
* The expected results are as follows:
|
|
* - Method invocations are expected to be slower than invoking a method on a
|
|
* conventional constructor instance. This is because of the method wrapper
|
|
* used by ease.js.
|
|
* - Public methods externally should be invoked very quickly. They are part
|
|
* of the class's prototype and therefore easily accessible.
|
|
* - Public methods /internally/ are likely to be invoked slightly more
|
|
* slowly. This is because it takes one extra step down the prototype chain
|
|
* to access them. The difference should be minute.
|
|
* - Protected and private methods internally should be accessed fairly
|
|
* quickly since, like public methods externally, they are first on the
|
|
* prototype chain.
|
|
* - Protected members will be accessed more slowly than private members,
|
|
* because they are one step lower on the prototype chain. Future versions
|
|
* will remove this performance hit if the Class contains no private
|
|
* members.
