| lfuns |
| |
| DESCRIPTION |
| A lfun is a LPC function within an object which is public and can |
| be called by other objects. In OO terms, lfuns are "methods" |
| which you can send "messages" to. |
| |
| Calling lfuns is done by using the efun call_other(), which |
| takes as arguments the object in which the lfun is to be called, |
| the name of the lfun to be called in the object, and additional |
| and optional arguments. |
| |
| An example looks like this: |
| |
| call_other(drink, "QueryShort"); |
| |
| This call may also be written as |
| |
| drink->QueryShort(); |
| |
| This means call_other(object, "function", args...) can also be |
| written as object->function(args...). The second form is |
| preferred as it is easier to read. |
| |
| Some lfuns have a special meaning for the LPC driver, because |
| they are applied by the interpreter instead from an LPC object. |
| To distinguish those, they are called ``applied lfuns''. |
