|
|
|
|
The C class is used to represent the actual data inside |
|
18
|
|
|
|
|
|
|
a file's C<__DATA__> section. |
|
19
|
|
|
|
|
|
|
|
|
20
|
|
|
|
|
|
|
One C object is used to represent the entire of the data, |
|
21
|
|
|
|
|
|
|
primarily so that it can provide a convenient handle directly to the data. |

|
The C method returns a L handle that allows you |
|
57
|
|
|
|
|
|
|
to do all the normal handle-y things to the contents of the __DATA__ |
|
58
|
|
|
|
|
|
|
section of the file. |
|
59
|
|
|
|
|
|
|
|
|
60
|
|
|
|
|
|
|
Unlike in perl itself, this means you can also do things like C |
|
61
|
|
|
|
|
|
|
new data onto the end of the __DATA__ section, or modify it with |
|
62
|
|
|
|
|
|
|
any other process that can accept an L as input or output. |
|
63
|
|
|
|
|
|
|
|
|
64
|
|
|
|
|
|
|
Returns an L object. |
