Method Detail

getThumbnailDirectory

public File getThumbnailDirectory(Issue issue)

Returns the physical directory of the thumbnails for the given issue, creating if necessary.

Specified by:

getThumbnailDirectory in interface AttachmentStore

Parameters:

issue - the issue whose thumbnail directory you want.

Returns:

The issue's thumbnail directory.

getAttachmentDirectory

public File getAttachmentDirectory(Issue issue)

Returns the physical directory of the attachments for the given issue. This will create it if necessary.

Parameters:

issue - the issue whose attachment directory you want.

Returns:

The issue's attachment directory.

getAttachmentDirectory

public File getAttachmentDirectory(Issue issue,
                                   boolean createDirectory)

Returns the physical directory of the attachments for the given issue. This will create it if necessary.

Specified by:

getAttachmentDirectory in interface AttachmentStore

Parameters:

issue - the issue whose attachment directory you want.

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

Returns:

The issue's attachment directory.

getTemporaryAttachmentDirectory

public File getTemporaryAttachmentDirectory()

Specified by:

getTemporaryAttachmentDirectory in interface AttachmentStore

getAttachmentDirectory

public File getAttachmentDirectory(String attachmentDirectory,
                                   String projectKey,
                                   String issueKey)

Get the attachment directory for the given attachment base directory, project key, and issue key.

The idea is to encapsulate all of the path-joinery magic to make future refactoring easier if we ever decide to move away from attachment-base/project-key/issue-ket

Specified by:

getAttachmentDirectory in interface AttachmentStore

Parameters:

attachmentDirectory - base of attachments

projectKey - the project key the issue belongs to

issueKey - the issue key for the issue

Returns:

the directory attachments for this issue live in

computeIssueKeyForOriginalProjectKey

public static String computeIssueKeyForOriginalProjectKey(String originalProjectKey,
                                                          String issueKey)

getAttachmentFile

public File getAttachmentFile(Issue issue,
                              Attachment attachment)
                       throws DataAccessException

Returns the physical File for the given Attachment. This method performs better as it does not need to look up the issue object.

Specified by:

getAttachmentFile in interface AttachmentStore

Parameters:

issue - the issue the attachment belongs to.

attachment - the attachment.

Returns:

the file.

Throws:

DataAccessException - on failure getting required attachment info.

getAttachmentFile

public File getAttachmentFile(Attachment attachment)
                       throws DataAccessException

Returns the physical File for the given Attachment. If you are calling this on multiple attachments for the same issue, consider using the overridden method that passes in the issue. Else, this goes to the database for each call.

Specified by:

getAttachmentFile in interface AttachmentStore

Parameters:

attachment - the attachment.

Returns:

the file.

Throws:

DataAccessException - on failure getting required attachment info.

getAttachmentFile

public File getAttachmentFile(AttachmentStore.AttachmentAdapter attachment,
                              File attachmentDir)

This is intended for cases where you want more control over where the attachment actually lives and you just want something to handle the look up logic for the various possible filenames an attachment can have.

In practice, this is just used during Project Import

Specified by:

getAttachmentFile in interface AttachmentStore

Parameters:

attachment - it's not an attachment but it acts like one for our purposes.

attachmentDir - the directory the attachments live in. This is different that the system-wide attachment directory. i.e. this would "attachments/MKY/MKY-1" and not just "attachments"

Returns:

the actual attachment

getThumbnailFile

public File getThumbnailFile(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 epheral objects anyway. http://jira.atlassian.com/browse/JRA-23311

Specified by:

getThumbnailFile in interface AttachmentStore

Parameters:

attachment - the attacment in play

Returns:

the full thumbnail file name

getThumbnailFile

public File getThumbnailFile(Issue issue,
                             Attachment attachment)

Specified by:

getThumbnailFile in interface AttachmentStore

getLegacyThumbnailFile

public File getLegacyThumbnailFile(Attachment attachment)

Returns the old legacy file name for thumbnails http://jira.atlassian.com/browse/JRA-23311

Specified by:

getLegacyThumbnailFile in interface AttachmentStore

Parameters:

attachment - the attacment in play

Returns:

the full legacy thumbnail file name

checkValidAttachmentDirectory

public void checkValidAttachmentDirectory(Issue issue)
                                   throws AttachmentException
