|
|
An unordered iterable collection of key/value pairs that cannot contain two instances of the same key.
|
|
It optionally enforces the type of the key and the type of the associated value.
|
|
<p>
|
|
To create a Map:
|
|
<pre>
|
|
var map = new go.Map("string", "number");
|
|
map.add("one", 1);
|
|
map.add("two", 2);
|
|
map.add("three", 3);
|
|
// now map.count === 3
|
|
// and map.getValue("two") === 2
|
|
// and map.contains("zero") === false
|
|
</pre>
|
|
<p>
|
|
You can iterate over the key/value pairs in a Map:
|
|
<pre>
|
|
var it = aMap.iterator;
|
|
while (it.next()) {
|
|
window.console.log(it.key + ": " + it.value);
|
|
}
|
|
</pre>
|
|
Or:
|
|
<pre>
|
|
aMap.each(function(kvp) {
|
|
window.console.log(kvp.key + ": " + kvp.value);
|
|
});
|
|
</pre>
|
|
But note that there is no guaranteed ordering amongst the key/value pairs.
|
|
<p>
|
|
Call <a href="../symbols/Map.html#toKeySet" class="linkMethod">toKeySet</a> to get a read-only <a href="../symbols/Set.html" class="linkConstructor">Set</a> that holds all of the keys of a Map.
|
|
Iterating over that Set will produce values that are the keys in the Map.
|
|
<p>
|
|
Although not precisely implementing the features and semantics of the EcmaScript 6 <b>Map</b> class,
|
|
this <b>GoJS</b> Map class has synonyms for the following methods and property:
|
|
<ul>
|
|
<li><b>get(key)</b>: <a href="../symbols/Map.html#getValue" class="linkMethod">getValue</a></li>
|
|
<li><b>set(key,val)</b>: <a href="../symbols/Map.html#add" class="linkMethod">add</a></li>
|
|
<li><b>has(key)</b>: <a href="../symbols/Map.html#contains" class="linkMethod">contains</a></li>
|
|
<li><b>delete(key)</b>: <a href="../symbols/Map.html#remove" class="linkMethod">remove</a></li>
|
|
<li><b>clear()</b>: <a href="../symbols/Map.html#clear" class="linkMethod">clear</a></li>
|
|
<li><b>size</b>: <a href="../symbols/Map.html#count" class="linkProperty">count</a></li>
|
|
</ul>
