|
45
|
|
|
|
|
|
|
This is a container for lists of file name entries. It modifies the |
46
|
|
|
|
|
|
|
definition of hash to to be the file name portion of the absolute path. For |
47
|
|
|
|
|
|
|
instance: |
48
|
|
|
|
|
|
|
|
49
|
|
|
|
|
|
|
/my/directory/foo.jpg |
50
|
|
|
|
|
|
|
|
51
|
|
|
|
|
|
|
would be hashed as foo.jpg so that all instances of that name will be |
52
|
|
|
|
|
|
|
added to the same bucket. |
53
|
|
|
|
|
|
|
|
54
|
|
|
|
|
|
|
Other than the hash key definition, it inherits its behavior from FileHash::Base. |
