Blocks are pieces of executable code which can be evaluated by sending |
46 |
them a value-message (''value'', ''value:'', ''value:value:'' etc). |
|
1 | 47 |
|
1265 | 48 |
In smalltalk, Blocks provide the basic (and heavily used) mechanism |
49 |
for looping, enumerating collection elements, visitors, exception |
|
50 |
handling, unwinding, delayed execution and processes. |
|
51 |
||
1254 | 52 |
Blocks are never created explicitely; the only creation |
53 |
is done by the compilers, when some sourceCode is compiled to either |
|
54 |
machine or byteCode. |
|
55 |
||
20621 | 56 |
In the code, blocks are written as: |
57 |
[ |
|
58 |
expression1. |
|
59 |
... |
|
60 |
expressionN |
|
61 |
] |
|
62 |
It represents the computation inside the brackets, |
|
63 |
and can be passed around as argument, assigned to variables or returned from a block or method. |
|
64 |
Creation of a block does NOT evaluate its expressions. You have to give the block to someone, |
|
65 |
who asks it to evaluate itself. This is done by sending #value to the block. |
|
66 |
i.e. |
|
67 |
foo := [ Transcript showCR:'Hello World']. |
|
68 |
... |
|
69 |
foo value |
|
70 |
||
71 |
Blocks are used in many many ways; one particular use is as callback: |
|
72 |
|b| |
|
73 |
||
74 |
b := Button label:'Press me'. |
|
75 |
b action:[ Transcript showCR:'Hello']. |
|
76 |
b open. |
|
77 |
||
67 | 78 |
Blocks with arguments need a message of type ''value:arg1 ... value:argn'' |
79 |
for evaluation; the number of arguments passed when evaluating must match |
|
80 |
the number of arguments the block was declared with otherwise an error is |
|
20621 | 81 |
raised. |
82 |
Blocks without args need a ''value'' message for evaluation. |
|
83 |
||
84 |
another use of blocks is in the enumeration protocols: |
|
85 |
|coll| |
|
86 |
||
87 |
coll := #( 'one' 'two' 'three'). |
|
88 |
coll do:[:eachElement | Transcript showCR:eachElement ]. |
|
89 |
||
90 |
Blocks keep a reference to the context where it was declared - |
|
67 | 91 |
this allows blocks to access the methods arguments and/or variables. |
154 | 92 |
This is still true after the method has returned - since the |
67 | 93 |
block keeps this reference, the methods context will NOT die in this case. |
20621 | 94 |
(for experts: Smalltalk blocks are technically lambdas/closures) |
1 | 95 |
|
67 | 96 |
A return (via ^-statement) out of a block will force a return from the |
20621 | 97 |
block's method context (if it is still living). |
98 |
This is effectively a kind of long-jumps out of the method which declared the block |
|
99 |
and makes control structures and loops possible. |
|
100 |
If the method is not alive (i.e. has already returned), a return out of the |
|
101 |
block will trigger an error. |
|
1 | 102 |
|
67 | 103 |
Long-jump is done by defining a catchBlock as ''[^ self]'' |
18252 | 104 |
somewhere up in the calling-tree. Then, to do the long-jump from out of some |
67 | 105 |
deeply nested method, simply do: ''catchBlock value''. |
1 | 106 |

1293 | 107 |
[Instance variables:] |
1 | 108 |
|
222 | 109 |
home <Context> the context where this block was created (i.e. defined) |
20621 | 110 |
this may be a blockContext or a methodContext |
222 | 111 |
nargs <SmallInteger> the number of arguments the block expects |
112 |
sourcePos <SmallInteger> the character position of its source, in chars |
|
20621 | 113 |
relative to methods source beginning |
222 | 114 |
initialPC <SmallInteger> the start position within the byteCode |
20621 | 115 |
for compiled blocks, this is nil. |
222 | 116 |
|
117 |
||
1293 | 118 |
[Class variables:] |
222 | 119 |
|
120 |
InvalidNewSignal raised if a Block is tried to be created |
|
20621 | 121 |
with new (which is not allowed). |
122 |
Only the VM is allowed to create Blocks. |

even here, blocks are involved: |

(although, the compiler optimizes things if possible) |
