PPI::Cache(3)						User Contributed Perl Documentation					     PPI::Cache(3)

NAME
PPI::Cache - The PPI Document Caching Layer
SYNOPSIS
# Set the cache use PPI::Cache path => '/var/cache/ppi-cache'; # Manually create a cache my $Cache = PPI::Cache->new( path => '/var/cache/perl/class-PPI', readonly => 1, );
DESCRIPTION
"PPI::Cache" provides the default caching functionality for PPI. It integrates automatically with PPI itself. Once enabled, any attempt to load a document from the filesystem will be cached via cache. Please note that creating a PPI::Document from raw source or something other object will not be cached. Using PPI::Cache The most common way of using "PPI::Cache" is to provide parameters to the "use" statement at the beginning of your program. # Load the class but do not set a cache use PPI::Cache; # Use a fairly normal cache location use PPI::Cache path => '/var/cache/ppi-cache'; Any of the arguments that can be provided to the "new" constructor can also be provided to "use".
METHODS
new param => $value, ... The "new" constructor creates a new standalone cache object. It takes a number of parameters to control the cache. path The "path" param sets the base directory for the cache. It must already exist, and must be writable. readonly The "readonly" param is a true/false flag that allows the use of an existing cache by a less-privileged user (such as the web user). Existing documents will be retrieved from the cache, but new documents will not be written to it. Returns a new "PPI::Cache" object, or dies on error. path The "path" accessor returns the path on the local filesystem that is the root of the cache. readonly The "readonly" accessor returns true if documents should not be written to the cache. get_document $md5sum | $source The "get_document" method checks to see if a Document is stored in the cache and retrieves it if so. store_document $Document The "store_document" method takes a PPI::Document as argument and explicitly adds it to the cache. Returns true if saved, or "undef" (or dies) on error. FIXME (make this return either one or the other, not both)
TO DO
- Finish the basic functionality - Add support for use PPI::Cache auto-setting $PPI::Document::CACHE
