Here is an attempt at an implementation (untested):
Change
XMLStandardFileStream[Read|Write]StreamFactory class>>isSupportedImplementation
^ (XMLClassFinder hasClassNamed: #StandardFileStream)
and: [ (XMLClassFinder classNamed: #StandardFileStream)
isDeprecated not ]
New
subclasses XMLPharoFile[Read|Write]StreamFactory
XMLPharoFile[Read|Write]StreamFactory class>>#isSupportedImplementation
^ (XMLClassFinder hasClassNamed: #File)
and: [ (XMLClassFinder classNamed: #FileStream) isDeprecated ]
XMLPharoFileReadStreamFactory class>>basicOnPath: aPathString
^ aPathString asFileReference binaryReadStream
XMLPharoFileWriteStreamFactory class>>basicOnPath: aPathString
^ aPathString asFileName ensureDelete binaryWriteStream
File and FileStream have existed in Pharo for quite a while, it is only after
FileStream and subclasses where deprecated that we can speak of a real switch.
You also have XMLFileSystemFileHandle that could be used directly, I guess. But
you pass on paths as strings, so if you want to keep that, the above should
work AFAIKT.
