Method Detail

getThumbnailFile

@Nonnull
File getThumbnailFile(@Nonnull
                            Attachment attachment)

Just like the attachments themselves, thumbnails can succumb to file system encoding problems. However we are going to regenerate thumbnails by only using the new naming scheme and not the legacy one. We cant do this for attachments but we can for thumbnails since they are ephemeral objects anyway. http://jira.atlassian.com/browse/JRA-23311

Parameters:

attachment - the attachment for which to get the thumbnail file

Returns:

a non-null file handle (the file itself might not exist)

getThumbnailFile(com.atlassian.jira.issue.Issue, Attachment)

getThumbnailFile

@Nonnull
File getThumbnailFile(@Nonnull
                            Issue issue,
                            @Nonnull
                            Attachment attachment)

Returns the file handle for the given attachment's thumbnail. This method performs better than getThumbnailFile(Attachment) if you already have the issue.

Parameters:

issue - the issue to which the attachment belongs

attachment - the attachment for which to get the thumbnail file

Returns:

a non-null file handle (the file itself might not exist)

Parameters:

attachment - the attachment in play

Returns:

the full legacy thumbnail file name

getThumbnailDirectory

@Nonnull
File getThumbnailDirectory(@Nonnull
                                 Issue issue)

Parameters:

The issue's thumbnail directory.

Returns the physical directory of the thumbnails for the given issue.

Parameters:

issue - the issue whose thumbnail directory you want

createDirectory - If true, and the directory does not currently exist, then the directory is created.

Returns:

The issue's thumbnail directory.
