Blocks are pieces of executable code which can be evaluated by sending |
40 |
them a value-message (''value'', ''value:'', ''value:value:'' etc). |
|
1 | 41 |
|
1265 | 42 |
In smalltalk, Blocks provide the basic (and heavily used) mechanism |
43 |
for looping, enumerating collection elements, visitors, exception |
|
44 |
handling, unwinding, delayed execution and processes. |
|
45 |
||
1254 | 46 |
Blocks are never created explicitely; the only creation |
47 |
is done by the compilers, when some sourceCode is compiled to either |
|
48 |
machine or byteCode. |
|
49 |
||
67 | 50 |
Blocks with arguments need a message of type ''value:arg1 ... value:argn'' |
51 |
for evaluation; the number of arguments passed when evaluating must match |
|
52 |
the number of arguments the block was declared with otherwise an error is |
|
53 |
raised. Blocks without args need a ''value'' message for evaluation. |
|
1 | 54 |
|
154 | 55 |
Blocks keep a reference to the context where the block was declared - |
67 | 56 |
this allows blocks to access the methods arguments and/or variables. |
154 | 57 |
This is still true after the method has returned - since the |
67 | 58 |
block keeps this reference, the methods context will NOT die in this case. |
222 | 59 |
(i.e. Blocks are closures in Smalltalk/X) |
1 | 60 |
|
67 | 61 |
A return (via ^-statement) out of a block will force a return from the |
62 |
blocks method context (if it is still living) - this make the implementation |
|
63 |
of long-jumps and control structures possible. |
|
154 | 64 |
(If the method is not alive (i.e. has already returned), a return out of the |
65 |
block will trigger an error) |
|
1 | 66 |
|
67 | 67 |
Long-jump is done by defining a catchBlock as ''[^ self]'' |
68 |
somewhere up in the calling-tree. Then, to do the long-jump from out of some |
|
69 |
deeply nested method, simply do: ''catchBlock value''. |

[Instance variables:] |
1 | 72 |

222 | 73 |
home <Context> the context where this block was created (i.e. defined) |
2238 | 74 |
this may be a blockContext or a methodContext |
222 | 75 |
nargs <SmallInteger> the number of arguments the block expects |
76 |
sourcePos <SmallInteger> the character position of its source, in chars |
|
2238 | 77 |
relative to methods source beginning |
222 | 78 |
initialPC <SmallInteger> the start position within the byteCode |
2238 | 79 |
for compiled blocks, this is nil. |
