33 | // Operators | |
34 | // | |
35 | // Lazy operators | |
36 | // | |
37 | // This class provides a mechanism for lazily evaluating operators. | |
38 | // Syntactically, a lazy operator looks like an ordinary C/C++ | |
39 | // infix, prefix or postfix operator. The operator application | |
40 | // looks the same. However, unlike ordinary operators, the actual | |
41 | // operator execution is deferred. (see actor.hpp, primitives.hpp | |
42 | // and composite.hpp for an overview). Samples: | |
43 | // | |
44 | // arg1 + arg2 | |
45 | // 1 + arg1 * arg2 | |
46 | // 1 / -arg1 | |
47 | // arg1 < 150 | |
48 | // | |
49 | // T1 set of classes implement all the C++ free operators. Like | |
50 | // lazy functions (see functions.hpp), lazy operators are not | |
51 | // immediately executed when invoked. Instead, a composite (see | |
52 | // composite.hpp) object is created and returned to the caller. | |
53 | // Example: | |
54 | // | |
55 | // (arg1 + arg2) * arg3 | |
56 | // | |
57 | // does nothing more than return a composite. T1 second function | |
58 | // call will evaluate the actual operators. Example: | |
59 | // | |
60 | // int i = 4, j = 5, k = 6; | |
61 | // cout << ((arg1 + arg2) * arg3)(i, j, k); | |
62 | // | |
63 | // will print out "54". | |
64 | // | |
65 | // Arbitrarily complex expressions can be lazily evaluated | |
66 | // following three simple rules: | |
67 | // | |
68 | // 1) Lazy evaluated binary operators apply when at least one | |
69 | // of the operands is an actor object (see actor.hpp and | |
70 | // primitives.hpp). Consequently, if an operand is not an actor | |
71 | // object, it is implicitly converted to an object of type | |
72 | // actor<value<T> > (where T is the original type of the | |
73 | // operand). | |
74 | // | |
75 | // 2) Lazy evaluated unary operators apply only to operands | |
76 | // which are actor objects. | |
77 | // | |
78 | // 3) The result of a lazy operator is a composite actor object | |
79 | // that can in turn apply to rule 1. | |
80 | // | |
81 | // Example: | |
82 | // | |
83 | // arg1 + 3 | |
84 | // | |
85 | // is a lazy expression involving the operator+. Following rule 1, | |
86 | // lazy evaluation is triggered since arg1 is an instance of an | |
87 | // actor<argument<N> > class (see primitives.hpp). The right | |
88 | // operand <3> is implicitly converted to an actor<value<int> >. | |
89 | // The result of this binary + expression is a composite object, | |
90 | // following rule 3. | |
91 | // | |
92 | // Take note that although at least one of the operands must be a | |
93 | // valid actor class in order for lazy evaluation to take effect, | |
94 | // if this is not the case and we still want to lazily evaluate an | |
95 | // expression, we can use var(x), val(x) or cref(x) to transform | |
96 | // the operand into a valid action object (see primitives.hpp). | |
97 | // Example: | |
98 | // | |
99 | // val(1) << 3; | |
100 | // | |
101 | // Supported operators: | |
102 | // | |
103 | // Unary operators: | |
104 | // | |
105 | // prefix: ~, !, -, +, ++, --, & (reference), * (dereference) | |
106 | // postfix: ++, -- | |
107 | // | |
108 | // Binary operators: | |
109 | // | |
110 | // =, [], +=, -=, *=, /=, %=, &=, |=, ^=, <<=, >>= | |
111 | // +, -, *, /, %, &, |, ^, <<, >> | |
112 | // ==, !=, <, >, <=, >= | |
113 | // &&, || | |
114 | // | |
115 | // Each operator has a special tag type associated with it. For | |
116 | // example the binary + operator has a plus_op tag type associated | |
117 | // with it. This is used to specialize either the unary_operator or | |
118 | // binary_operator template classes (see unary_operator and | |
119 | // binary_operator below). Specializations of these unary_operator | |
120 | // and binary_operator are the actual workhorses that implement the | |
121 | // operations. The behavior of each lazy operator depends on these | |
122 | // unary_operator and binary_operator specializations. 'preset' | |
123 | // specializations conform to the canonical operator rules modeled | |
124 | // by the behavior of integers and pointers: | |
125 | // | |
126 | // Prefix -, + and ~ accept constant arguments and return an | |
127 | // object by value. | |
128 | // | |
129 | // The ! accept constant arguments and returns a boolean | |
130 | // result. | |
131 | // | |
132 | // The & (address-of), * (dereference) both return a reference | |
133 | // to an object. | |
134 | // | |
135 | // Prefix ++ returns a reference to its mutable argument after | |
136 | // it is incremented. | |
137 | // | |
138 | // Postfix ++ returns the mutable argument by value before it | |
139 | // is incremented. | |
140 | // | |
141 | // The += and its family accept mutable right hand side (rhs) | |
142 | // operand and return a reference to the rhs operand. | |
143 | // | |
144 | // Infix + and its family accept constant arguments and return | |
145 | // an object by value. | |
146 | // | |
147 | // The == and its family accept constant arguments and return a | |
148 | // boolean result. | |
149 | // | |
150 | // Operators && and || accept constant arguments and return a | |
151 | // boolean result and are short circuit evaluated as expected. | |
