Class AttachmentViewCmdImpl
java.lang.Object
CacheableCommandImpl
com.ibm.commerce.command.AbstractECTargetableCommand
com.ibm.commerce.command.ControllerCommandImpl
com.ibm.commerce.command.AttachmentViewCmdImpl
- All Implemented Interfaces:
- AccCommand, AttachmentViewCmd, ControllerCommand, ECCommand, ECTargetableCommand, Protectable
- Direct Known Subclasses:
- OrderItemAttachmentViewCmdImpl, RFQAttachmentViewCmdImpl
- public class AttachmentViewCmdImpl
- extends ControllerCommandImpl
- implements AttachmentViewCmd
The AttachmentViewCmdImpl will retrieve the attachment content from database and return the stream as DirectView to browser if the attachmentURL is same as attachment_id If the attachmentURL is not the same as attachment_id, we will assume that the attachment is not stored as BLOB in attachment table in database. We will open up the file as specified in AttachmentURL and return the stream as DirectView to browser AttachmentViewCmdImpl is only intended to be extended and not used directly . The AttachmentViewCmdImpl is not registered in the URLREG or CMDREG
