DataHandler.getInputStream介绍

[英]Get the InputStream for this object.

For DataHandlers instantiated with a DataSource, the DataHandler calls the DataSource.getInputStream method and returns the result to the caller.

For DataHandlers instantiated with an Object, the DataHandler first attempts to find a DataContentHandler for the Object. If the DataHandler can not find a DataContentHandler for this MIME type, it throws an UnsupportedDataTypeException. If it is successful, it creates a pipe and a thread. The thread uses the DataContentHandler's writeTo method to write the stream data into one end of the pipe. The other end of the pipe is returned to the caller. Because a thread is created to copy the data, IOExceptions that may occur during the copy can not be propagated back to the caller. The result is an empty stream.
[中]获取此对象的InputStream。
对于使用数据源实例化的DataHandler，DataHandler调用DataSource.getInputStream方法并将结果返回给调用者。
对于使用对象实例化的DataHandler，DataHandler首先尝试查找对象的DataContentHandler。如果DataHandler找不到此MIME类型的DataContentHandler，它将抛出UnsupportedDataTypeException。如果成功，它将创建一个管道和一个螺纹。线程使用DataContentHandler的writeTo方法将流数据写入管道的一端。管道的另一端返回给调用者。因为创建线程是为了复制数据，所以复制过程中可能发生的IOException不能传播回调用方。结果是一个空流。
