Code::TidyAll::CacheModel - caching model for Cody::TidyAll

SYNOPSIS

my $cache_model = Cody::TidyAll::CacheModel->new(
   cache_engine => Code::TidyAll::Cache->new(...),
   path => "/path/to/file/to/cache",
);

# check cache
print "Yes!" if $cache_model->is_cached;

# update cache
$cache_model->clear_file_contents;
$cache_model->update;

# update the cache when you know the file contents
$cache_model->file_contents( $new_content );
$cache_model->update;

# force removal from cache
$cache_model->remove;

DESCRIPTION

A cache model for Code::TidyAll. Different subclasses can employ different caching techniques.

The basic model implemented here is simple; It stores in the cache a hash key of the file contents keyed by a hash key of the file's path.

Attributes

full_path (required, ro)

The full path to the file on disk

path (required, ro)

The local path to the file (i.e. what the cache system will consider the canonical name of the file)

cache_engine (optional, default undef, ro)

A Code::TidyAll::Cache compatible instance, or, if no caching is required undef.

base_sig (optional, default empty string, ro)

A base signature.

file_contents (optional, default loads file contents from disk, rw)

is_cached (optional, default computed, rw)

A flag indicating if this is cached. By default checks that the cache key and cache value match the cache.

Methods

cache_key

The computed cache key for the file

cache_value

The computed cache value for the file

update

Updates the cache

remove

Attempts to remove the value from the cache
