Method Details

readFile

public byte[] readFile(String path)
                throws IOException

Description copied from interface: IFileReader

Reads a file from disk.

Specified by:

readFile in interface IFileReader

Throws:

IOException

getCacheLock

public ReentrantLock getCacheLock()

Returns the lock used to prevent concurrent modification exceptions when mutating the LRU cache data.
This may be useful if you need to access the LRU cache, which, owing to how a least-recently-used cache works, will cause the data to mutate, and which requires to be protected with locks.

Specified by:

getCacheLock in interface IFileReader

getLruCache

public Map<String,byte[]> getLruCache()

Description copied from interface: IFileReader

Returns the LRU (least-recently-used) cache that is filled when using IFileReader.readFile(String)

Specified by:
