Description

The parser of PDFBox uses the current implementation of ScratchFile/ScratchFileBuffer exclusively as cache for streams when creating/writing COSStreams.

Using an interface to handle those caches

• makes the parser code of PDFBox independent of a specific implementation of that cache
• gives any user the opportunity to implement some other kind of a cache
• the current implementation of ScratchFile/ScratchFileBuffer can still be used as default
