Class E4ValidatorFileUpload

java.lang.Object
  e4s.util.E4Object
      e4s.html.input.extended.E4ValidatorFileUpload

All Implemented Interfaces:

AEP_ValidationObject_Intf

public class E4ValidatorFileUpload
extends E4Object
implements AEP_ValidationObject_Intf

Validates an File upload. Validation only takes care of IO errors during upload - for example, when a file's size (or if there are more files the total size) exceeds the limit configurated in E4Settings.getMaxUploadSize() this validation is necessary to display the problems along with the file input.

Since:

JDK 1.4
