Example: Loading using CfsFileDescriptor

Migration Guide : Migrating from VisualAge Smalltalk V3.0 or earlier : Swapper : Dumping, loading, and the Common File System subsystem : Example: Loading using CfsFileDescriptor

The file handle parameter required by the ObjectLoader must also be an instance of CfsFileDescriptor. This example shows how loadFromFileHandle:atOffset: is used.

| aCfsFileDescriptor someObject |

aCfsFileDescriptor := CfsFileDescriptor

open: 'someobj.swp'

oflag: ORDONLY.

aCfsFileDescriptor isCfsError

ifTrue: [^self error: 'Cannot open file'].

someObject := ObjectLoader new

loadFromFileHandle: aCfsFileDescriptor

atOffset: 0.

aCfsFileDescriptor close.

someObject inspect.
