Class URLDataSource

java.lang.Object  |  +--javax.activation.URLDataSource

All Implemented Interfaces:: DataSource

public classURLDataSource
extends java.lang.Object
implementsDataSource

The URLDataSource class provides an object that wraps aURL object in a DataSource interface. URLDataSource simplifies the handling of data described by URLs within the JavaBeans Activation Framework because this class can be used to create new DataHandlers.NOTE: The DataHandler object creates a URLDataSource internally, when it is constructed with a URL.
