/**
|
44 |
|
|
* Array holds static helper functions that allow you to create and
|
45 |
|
|
* manipulate arrays by reflection. Operations know how to perform widening
|
46 |
|
|
* conversions, but throw {@link IllegalArgumentException} if you attempt
|
47 |
|
|
* a narrowing conversion. Also, when accessing primitive arrays, this
|
48 |
|
|
* class performs object wrapping and unwrapping as necessary.<p>
|
49 |
|
|
*
|
50 |
|
|
* <B>Note:</B> This class returns and accepts types as Classes, even
|
51 |
|
|
* primitive types; there are Class types defined that represent each
|
52 |
|
|
* different primitive type. They are <code>java.lang.Boolean.TYPE,
|
53 |
|
|
* java.lang.Byte.TYPE,</code>, also available as <code>boolean.class,
|
54 |
|
|
* byte.class</code>, etc. These are not to be confused with the
|
55 |
|
|
* classes <code>java.lang.Boolean, java.lang.Byte</code>, etc., which are
|
56 |
|
|
* real classes. Note also that the shorthand <code>Object[].class</code>
|
57 |
|
|
* is a convenient way to get array Classes.<p>
|
58 |
|
|
*
|
59 |
|
|
* <B>Performance note:</B> This class performs best when it does not have
|
60 |
|
|
* to convert primitive types. The further along the chain it has to convert,
|
61 |
|
|
* the worse performance will be. You're best off using the array as whatever
|
62 |
|
|
* type it already is, and then converting the result. You will do even
|
63 |
|
|
* worse if you do this and use the generic set() function.
