Opens and parses a pack file, loading its directory into memory. Automatically done in VirtualFS from the configuration.

Checks whether the pack contains an entry for the given path.

Parameters

relativePath

Virtual resource path (e.g. "shaders/pbr.vert").

Returns

true if an entry with that path exists, false otherwise.

Checks whether the directory contains any entry whose path starts with the given prefix.

Parameters

prefix

Path prefix to search for.

Returns

true if at least one entry matches, false otherwise.

Iterates over the entries located under a directory prefix.

Directories are implicit in the pack format: they are derived from the stored entry paths and each one is reported exactly once.

Parameters

directoryPath	Directory path inside the pack (empty string for the root).
callback	Called for each entry with isDirectory and the path relative to directoryPath.
recursive	If true, also reports the entries of the sub-directories.

Loads the raw bytes of a resource into a caller-supplied buffer.

The buffer is resized to fit the resource exactly before the data is copied into it.

Subclasses can override this to transform the loaded bytes (e.g. decryption).

Creates a streaming buffer over a resource region without loading the entire resource into memory.

The returned ResourcesPackStreambuf can be wrapped in a std::istream to enable incremental, standard-library-compatible reading.

Parameters

relativePath

Virtual resource path.

Returns

A shared pointer to the streambuf; the underlying file handle is owned by this ResourcesPack instance
