# Cache Reader
The entry point to a cache: {ref}`TCacheReader.Create` opens one, and its `Indices` are the
{ref}`TCacheIndex` records everything else is read through.

The global `CacheReader` is what the rest of this library reads from, so assign to it rather
than keeping your own.

## CacheReader.Load
```pascal
procedure TCacheReader.Load();
```
Reads the cache's data file and its master index off disk, then opens one {ref}`TCacheIndex`
per index file listed in the master index.

`Path` must already be set. Call this again to pick up a cache that has changed on disk.

## CacheReader.Create
```pascal
function TCacheReader.Create(path: String): TCacheReader; static;
function TCacheReader.Create(): TCacheReader; static; overload;
```
Opens the cache that a client keeps under `path`, which is the directory holding `jagexcache`
rather than the cache directory itself.

The overload without arguments uses the RuneLite cache in the current user's home directory.

Opening the cache reads every index's reference table, so afterwards you know which archives
exist and what is in them, but no archive's contents have been decompressed yet - that is what
{ref}`TCacheIndex.Cache` is for.

Example:
```pascal
CacheReader := TCacheReader.Create();
CacheReader.Indices[ECacheIndex.CONFIGS].Cache();
```
