Method Details

storeResource

public void storeResource(AttachmentResource resource,
 ContentEntityObject ceo)

Description copied from interface: FileUploadManager

Stores the attachmentResource as an Attachment on the specified content object.

Specified by:

storeResource in interface FileUploadManager

Parameters:

resource - contains the required state to create an attachment

ceo - the content object which the attachment will be attached to

storeResources

public void storeResources(@NonNull Collection<AttachmentResource> attachmentResources,
 ContentEntityObject content)

Stores one or more attachment resources against the given content.

This is the single choke-point for all upload paths (UI, drag-and-drop, REST, SOAP). To guard against concurrent uploads to the same content it applies two layers of protection:

1. Per-content cluster lock (withUploadLock(long, java.lang.Runnable)) — serialises all uploads to the same content ID across every node in the cluster. Uploads to different content proceed concurrently.
2. Retry loop — re-attempts the store on transient OptimisticLockingFailureExceptions (default: 2 attempts).

Specified by:

storeResources in interface FileUploadManager

Parameters:

attachmentResources - the attachments to store

content - the content to attach them to; used only to obtain the content ID — the entity is reloaded inside each transaction attempt
