Description copied from interface: AttachmentStore

Checks that the Attachment directory of the given issue is right to go - writable, accessible etc. Will create it if necessary.

Specified by:

checkValidAttachmentDirectory in interface AttachmentStore

Parameters:

issue - the issue whose attachment directory to check.

Throws:

AttachmentException - if the directory is not writable or missing and cannot be created.

checkValidTemporaryAttachmentDirectory

public void checkValidTemporaryAttachmentDirectory()
                                            throws AttachmentException

getAttachmentFile

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

Description copied from interface: AttachmentStore

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:

adapter - 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

@Nonnull
public File getThumbnailFile(Attachment attachment)

Description copied from interface: AttachmentStore

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 can't do this for attachments, but we can for thumbnails since they are ephemeral objects anyway. http://jira.atlassian.com/browse/JRA-23311

Specified by:

getThumbnailFile in interface AttachmentStore

Parameters:

attachment - the attachment for which to get the thumbnail file

Returns:

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

See Also:

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

getThumbnailFile

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

Description copied from interface: AttachmentStore

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

Specified by:

getThumbnailFile in interface AttachmentStore

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)

See Also:

AttachmentStore.getThumbnailFile(Attachment)

getLegacyThumbnailFile

public File getLegacyThumbnailFile(Attachment attachment)

Description copied from interface: AttachmentStore

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

Specified by:

getLegacyThumbnailFile in interface AttachmentStore

Parameters:

attachment - the attachment in play

Returns:

the full legacy thumbnail file name

getAttachmentFile

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

Description copied from interface: AttachmentStore

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

Description copied from interface: AttachmentStore

Returns the physical File for the given Attachment. If you are calling this on multiple attachments for the same issue, consider using the overriden 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.

putAttachment

public com.atlassian.util.concurrent.Promise<Attachment> putAttachment(Attachment metadata,

source - source data. The attachment store will close this stream when it has completed. The stream will be closed once the operation is complete.

Returns:

A promise of an attachment that performs the 'put' operation once the promise is claimed. The promise will contain an AttachmentRuntimeException in case of error.

putAttachment

Returns:

A promise of an attachment that performs the 'put' operation once the promise is claimed.

getAttachment
