keys - return an array of the keys from the (key, value) pairs in a mapping
|
|
|
|
array keys( mapping m );
|
|
|
|
keys() returns an array of keys (indices) corresponding to the keys in
|
|
the (key, value) pairs stored in the mapping m.
|
|
|
|
For example, if:
|
|
|
|
<pre>
|
|
mapping m;
|
|
m = (["hp" : 35, "sp" : 42, "mass" : 100]);
|
|
</pre>
|
|
|
|
then
|
|
|
|
<pre>
|
|
keys(m) == ({"hp", "sp", "mass"})
|
|
</pre>
|
|
|
|
Note: the keys will not be returned in any apparent order. However, they
|
|
will be returned in the same order as the corresponding values (returned
|
|
by the values() efun).
