NAME
FileCache::Handle - A FileCache using IO::Handle instances
SYNOPSIS
use FileCache::Handle;
$FileCache::Handle::MAX = 16;
my @a;
for (my $i = 0 ; $i < 100 ; $i++) {
my $o = new FileCache::Handle("/tmp/$i");
binmode($o, ':utf8');
push @a, $o;
}
for (my $i = 0 ; $i < 3 ; $i++) {
foreach my $o (@a) {
print $o "Output ",$o," $i\n";
}
}
DESCRIPTION
FileCache::Handle, like FileCache, avoids OS-imposed limits on the
number of simultaneously open files. Instances behave like file handles
and, behind the scenes, real files are opened and closed as necessary.
FileCache::Handle uses instances of IO::Handle, and so works well with
'use strict'.
NOTES
The only operations supported are 'print' and 'binmode'. To add more,
create a glue method that delegates the call to the handle returned by
'_allocate()'.
Unless MAX is set, this class will open as many files as possible before
closing any. As such, it will monopolise available files, so you should
open any other files beforehand.
