| <p> |
| Care and attention to detail was given, painstakingly, to the design and implementation |
| of Phoenix. |
| </p> |
| <p> |
| The library is organized in four layers: |
| </p> |
| <div class="orderedlist"><ol class="orderedlist" type="1"> |
| <li class="listitem"> |
| Actor |
| </li> |
| <li class="listitem"> |
| Value, Reference, Arguments |
| </li> |
| <li class="listitem"> |
| Function, Operator, Object, Statement, Scope |
| </li> |
| <li class="listitem"> |
| STL, Fusion, Bind |
| </li> |
| </ol></div> |
| <p> |
| The modules are orthogonal, with no cyclic dependencies. Lower layers do not |
| depend on higher layers. Modules in a layer do not depend on other modules |
| in the same layer. This means, for example, that Bind can be completely discarded |
| if it is not required; or one could perhaps take out Operator and Statement |
| and just use Function, which may be desirable in a pure FP application. |
| </p> |
| <p> |
| The library has grown from the original Phoenix but still comprises only header |
| files. There are no object files to link against. |
| </p> |
| <h3> |
| <a name="phoenix.organization.h0"></a> |
| <span class="phrase"><a name="phoenix.organization.core"></a></span><a class="link" href="organization.html#phoenix.organization.core">Core</a> |
| </h3> |
| <p> |
| The lowest two layers comprise the core. |
| </p> |
| <p> |
| The <a class="link" href="actor.html" title="Actor"><code class="computeroutput"><span class="identifier">Actor</span></code></a> |
| is the main concept behind the library. Lazy functions are abstracted as actors. |
| </p> |
| <p> |
| Terminals provide the basic building blocks of functionality within Phoenix. |
| Expressions are used to combine these terminals together to provide more powerful |
| functionality. |
| </p> |
| <p> |
| Expressions are composed of zero or more actors. Each actor in a composite |
| can again be another expression. |
