In memory limited systems (as my 8Mb 386 is) all seldom-used classes are made |
|
2662 | 41 |
subclasses of this class. |
42 |
Autoload catches all messages and files-In the corresponding code |
|
43 |
when first used. |
|
2689 | 44 |
Then the caught message is resent to the (now existing) class. |
2662 | 45 |
|
46 |
Class files are searched along the searchPath (see Smalltalk), |
|
47 |
and any of binary-classFile, byteCode-classFile or sourceFile are |
|
48 |
loaded, whichever is found first. For binaries to be loaded, |
|
49 |
these must be found in the 'bin' directory. Sources must be found |
|
50 |
in the 'source' directory. |
|
51 |
(Usually, Autoload classes finds the source file and loads that one). |
|
52 |

When started, the patches startup script arranges for the abbreviation |
|
54 |
file 'include/abbrev.stc' to be read and installs autoload stubs for |

all classes listed in that file, which do not exist already. |
2662 | 56 |
The abbreviation file is maintained by the production environment |
57 |
and updated by makefile rules - therefore, it should not be edited |
|
58 |
manually. |

Late addition: above comment is no longer true - I have made now almost |
