.SH "NAME"
Cache::CacheSizer \-\- component object for managing the size of caches
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The CacheSizer class is used internally in SizeAware caches such as
SizeAwareFileCache to encapsulate the logic of limiting cache size.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&  use Cache::CacheSizer;
\&
\&  my $sizer = new Cache::CacheSizer( $cache, $max_size );
\&
\&  $sizer\->limit_size( $new_size );

.SH "METHODS"
.IX Header "METHODS"
.IP "\fBnew( \f(CB$cache\fB, \f(CB$max_size\fB )\fR" 4
.IX Item "new( $cache, $max_size )"
Construct a new Cache::CacheSizer object for the cache \fI\f(CI$cache\fI\fR with
a maximum size of \fI\f(CI$max_size\fI\fR.
.IP "\fBupdate_access_time( \f(CB$key\fB )\fR" 4
.IX Item "update_access_time( $key )"
Inform the cache that the object specified by \fI\f(CI$key\fI\fR has been accessed.
.IP "\fBlimit_size( \f(CB$new_size\fB )\fR" 4
.IX Item "limit_size( $new_size )"
Use the sizing algorithms to get the cache down under \fI\f(CI$new_size\fI\fR if
possible.
.SH "PROPERTIES"
.IX Header "PROPERTIES"
.IP "\fBget_max_size\fR" 4
.IX Item "get_max_size"
