__init__()

__init__(param0: Decompressor)

decompress(source_file: Filename) → bool

Performs a foreground decompression of the named file; does not return until the decompression is complete.

decompress(source_and_dest_file: Ramfile) → bool

Does an in-memory decompression of the indicated Ramfile. The decompressed contents are written back into the same Ramfile on completion.

get_progress() → float

Returns the ratio through the decompression step in the background.

initiate(source_file: Filename) → int

Begins a background decompression of the named file (whose filename must end in “.pz”) to a new file without the .pz extension. The source file is removed after successful completion.

initiate(source_file: Filename, dest_file: Filename) → int

Begins a background decompression from the named source file to the named destination file. The source file is removed after successful completion.

property progress → float

Returns the ratio through the decompression step in the background.

run() → int

Called each frame to do the next bit of work in the background task. Returns EU_ok if a chunk is completed but there is more to go, or EU_success when we’re all done. Any other return value indicates an error.
