48
- *
49
- * $traversableInfo
50
- * @define mutability
51
- * @define traversableInfo
52
- * This is a base trait of all kinds of $mutability Scala collections. It
53
- * implements the behavior common to all collections, in terms of a method
54
- * `foreach` with signature:
55
- * {{{
56
- * def foreach[U](f: Elem => U): Unit
57
- * }}}
58
- * Collection classes mixing in this trait provide a concrete
59
- * `foreach` method which traverses all the
60
- * elements contained in the collection, applying a given function to each.
61
- * They also need to provide a method `newBuilder`
62
- * which creates a builder for collections of the same kind.
63
- *
64
- * A traversable class might or might not have two properties: strictness
65
- * and orderedness. Neither is represented as a type.
66
- *
67
- * The instances of a strict collection class have all their elements
68
- * computed before they can be used as values. By contrast, instances of
69
- * a non-strict collection class may defer computation of some of their
70
- * elements until after the instance is available as a value.
71
- * A typical example of a non-strict collection class is a
72
- * <a href="../immutable/Stream.html" target="ContentFrame">
73
- * `scala.collection.immutable.Stream`</a>.
74
- * A more general class of examples are `TraversableViews`.
75
- *
76
- * If a collection is an instance of an ordered collection class, traversing
77
- * its elements with `foreach` will always visit elements in the
78
- * same order, even for different runs of the program. If the class is not
79
- * ordered, `foreach` can visit elements in different orders for
80
- * different runs (but it will keep the same order in the same run).'
81
- *
82
- * A typical example of a collection class which is not ordered is a
83
- * `HashMap` of objects. The traversal order for hash maps will
84
- * depend on the hash codes of its elements, and these hash codes might
85
- * differ from one run to the next. By contrast, a `LinkedHashMap`
86
- * is ordered because it's `foreach` method visits elements in the
87
- * order they were inserted into the `HashMap`.

- JavaScript mode supports several configuration options:

- <ul>
94
- <li><code>json</code> which will set the mode to expect JSON
95
- data rather than a JavaScript program.</li>
96
- <li><code>jsonld</code> which will set the mode to expect
97
- <a href="http://json-ld.org">JSON-LD</a> linked data rather
98
- than a JavaScript program (<a href="json-ld.html">demo</a>).</li>
99
- <li><code>typescript</code> which will activate additional
100
- syntax highlighting and some other things for TypeScript code
101
- (<a href="typescript.html">demo</a>).</li>
102
- <li><code>statementIndent</code> which (given a number) will
103
- determine the amount of indentation to use for statements
104
- continued on a new line.</li>
105
- <li><code>wordCharacters</code>, a regexp that indicates which
106
- characters should be considered part of an identifier.
107
- Defaults to <code>/[\w$]/</code>, which does not handle
108
- non-ASCII identifiers. Can be set to something more elaborate
109
- to improve Unicode support.</li>
