AttachmentsClassLoader

class AttachmentsClassLoader : SecureClassLoader

A custom ClassLoader that knows how to load classes from a set of attachments. The attachments themselves only need to provide JAR streams, and so could be fetched from a database, local disk, etc. Constructing an AttachmentsClassLoader is somewhat expensive, as every attachment is scanned to ensure that there are no overlapping file paths.



Exceptions

OverlappingAttachments class OverlappingAttachments : Exception
