Function Import
I had requested this feature along time ago and the new function objects have made it possible now.
This will create function pointers in an object. Variable list:
fromobj - Object, The object you want to import functions from.
toobj - Object, The object you want to import functions to.
fromprefix - String, Only import functions starting with this text. If null, all functions imported.
toprefix - String, Imported functions will be prefixed with this.
events - Boolean, Should functions starting with "on" be included in the operations?
PHP Code:
public function import(fromobj, toobj, fromprefix, toprefix, events) {
temp.vars = 0;
temp.i = 0;
if (fromobj.type() != 2 || toobj.type() != 2) {
echo("System: Import Error");
return;
}
vars = fromobj.getFunctions();
if (fromprefix != null) {
for (i: vars) {
if (i.starts("on") && events == false)
continue;
if (fromobj.(@ i).starts(fromprefix)) {
if (toprefix == null) {
toobj.(@ i) = fromobj.(@ i);
toobj.importedfunctions.add(i);
}
else {
toobj.(@ toprefix @ i) = fromobj.(@ i);
toobj.importedfunctions.add(toprefix @ i);
}
}
}
}
else {
for (i: vars) {
if (i.starts("on") && events == false)
continue;
if (toprefix == null) {
toobj.(@ i) = fromobj.(@ i);
toobj.importedfunctions.add(i);
}
else {
toobj.(@ toprefix @ i) = fromobj.(@ i);
toobj.importedfunctions.add(toprefix @ i);
}
}
}
}
public function deport(obj) {
temp.vars = 0;
temp.i = 0;
vars = obj.importedfunctions;
for (i: vars) {
obj.(@ i) = null;
}
}
Example:
PHP Code:
// WEAPON: InverTest
function testf(text) {
echo("TESTF: " @ text);
}
function test2(text) {
echo("Test2: " @ text);
}
PHP Code:
// WEAPON: InverTest2
function onCreated() {
System.import(InverTest, this, "test", null, false); // importing functions that start with 'test'
testf("ZOMG");
test2("RAWR");
System.deport(this); // removes imported functions
}
PHP Code:
// Example script
function onCreated() {
System.import(MudControl, this, null, "mud_", false);
// Importing all functions from MudControl and prefixing with mud_ to remove conflict.
}
I've also noted that using this method can be used even if the imported functions are not public. |
