Class FileNameBasedVersionedAttachmentsList

java.lang.Object
  com.atlassian.jira.bc.issue.attachment.FileNameBasedVersionedAttachmentsList

All Implemented Interfaces:

VersionedAttachmentsList

public class FileNameBasedVersionedAttachmentsList
extends Object
implements VersionedAttachmentsList

This implementation wraps a list of attachments and adds the concept of attachment 'versions' by grouping attachments that have the same filename as versions of the same file. It stores this 'version' information when constructed by building up a Map with keys for every distinct file name in the underlying List of attachments. Then, each key's value is a TreeSet of attachments which have that filename.

Since:

v4.2
