public class CopyAttachmentCmdImpl
extends TaskCommandImpl
implements CopyAttachmentCmd

This class makes a copy of the attachment object as specified by org_attachmentobj_id. A new attachment object will be created and the new attachment object_id will be returned. The copy made will be a field by field copy including the timecreated, timeupated and markfordelete fields. The reserved field will be copied from the original attachment object to the new attachment object.

If the attachmentURL is the same as the org_attachment_id in the attachment table, the content of the attachment is stored in BLOB. It will be copied into the new attachment table as BLOB as well.

If the attachmentURL is not the same as the attachment_id, the attachment is stored on the file system as specified in the attachmentURL. The file will be opened as specified in the attachmentURL in the original attachment object. A new unique file name will be generated, and the file content will be copied into the new file. The new filename will be the attachmenturl of the new attachment object.

Note that when the attachment object is deleted during DBClean, a log of the attachmenturl will be generated if the attachment is stored on the file system. It is up to the user to delete the file.

This class does not provide access control checking. The command writer should implement his/her own access control checking and make sure the caller is authorized to make a copy of the attachment object.
