public class RAMDirectory : Directory

Name	Description
RAMDirectory()	Constructs an empty Directory.
RAMDirectory(Directory)	Creates a new `RAMDirectory` instance from a different `Directory` implementation. This can be used to load a disk-based index into memory. This should be used only with indices that can fit into memory. Note that the resulting `RAMDirectory` instance is fully independent from the original `Directory` (it is a complete copy). Any subsequent changes to the original `Directory` will not be visible in the `RAMDirectory` instance.

Name	Description
CreateOutput(String)	Creates a new, empty file in the directory with the given name. Returns a stream writing this file.
DeleteFile(String)	Removes an existing file in the directory.
Dispose(Boolean)	Closes the store to future operations, releasing associated memory.
FileExists(String)	Returns true iff the named file exists in this directory.
FileLength(String)	Returns the length in bytes of a file in the directory.
FileModified(String)	Returns the time the named file was last modified.
ListAll()
OpenInput(String)	Returns a stream reading an existing file.
SizeInBytes()	Return total size in bytes of all files in this directory. This is currently quantized to RAMOutputStream.BUFFER_SIZE.
TouchFile(String)	Set the modified time of an existing file to now.
