Class PayloadFilesManager

java.lang.Object

org.glassfish.admin.payload.PayloadFilesManager

Direct Known Subclasses:

PayloadFilesManager.Perm, PayloadFilesManager.Temp

public abstract class PayloadFilesManager
extends Object

Manages transferred files delivered via the request or response Payload.

Callers can process the entire payload at once, treating each Part as a file, using the processParts(org.glassfish.api.admin.Payload.Inbound) method. Or, the caller can invoke the #processPart method to work with a single Part as a file.

If the caller wants to extract the payload's content as temporary files it should instantiate PayloadFilesManager.Temp which exposes a PayLoadFilesManager.Temp#cleanup method. The caller should invoke this method once it has finished with the transferred files, although the finalizer will invoke cleanup just in case.

On the other hand, if the caller wants to keep the transferred files it should instantiate PayloadFilesManager.Perm.

Temp uses a unique temporary directory, then creates one temp file for each part it is asked to deal with, either from an entire payload (processParts(org.glassfish.api.admin.Payload.Inbound)) or a single part (#processPart(org.glassfish.api.admin.Payload.Part)). Recall that each part in the payload has a name which is a relative or absolute URI.
