Classes

class Pyjo.Asset.File.Pyjo_Asset_File(**kwargs)

Pyjo.Asset.File inherits all attributes and methods from Pyjo.Asset and implements the following new ones.

add_chunk(chunk='')

asset_file = asset_file.add_chunk(b'foo bar baz')

Add chunk of data.

cleanup = None

boolean = asset_file.cleanup
asset_file.cleanup = boolean

Delete path automatically once the file is not used anymore.

close()

asset_file.close()

Close asset immediately and free resources.

contains(bstring)

position = asset_file.contains(b'bar')

Check if asset contains a specific string.

get_chunk(offset, maximum=131072)

bstream = asset.get_chunk(offset)
bstream = asset.get_chunk(offset, maximum)

Get chunk of data starting from a specific position, defaults to a maximum chunk size of 131072 bytes (128KB).

handle

handle = asset_file.handle
asset_file.handle = open('/home/pyjo/foo.txt', 'rb')

Filehandle, created on demand.

is_file

true = asset_file.is_file

True.

move_to(dst)

asset_file = asset_file.move_to('/home/pyjo/bar.txt')

Move asset data into a specific file and disable cleanup.

mtime

mtime = asset_file.mtime

Modification time of asset.

path = None

path = asset_file.path
asset_file.path = '/home/pyjo/foo.txt'

File path used to create handle, can also be automatically generated if necessary.

size

size = asset_file.size

Size of asset data in bytes. Reading the size flushes writing buffer.

slurp()

bstring = asset_file.slurp()

Read all asset data at once.

tmpdir = None

tmpdir = asset_file.tmpdir
asset_file.tmpdir = '/tmp'

Temporary directory used to generate path, defaults to the value of the PYJO_TMPDIR environment variable or auto detection.
