类名称：MimeMessage
方法名：getDataHandler

MimeMessage.getDataHandler介绍

[英]Return a DataHandler for this Message's content.

The implementation provided here works approximately as follows. Note the use of the getContentStream method to generate the byte stream for the content. Also note that any transfer-decoding is done automatically within this method.

getDataHandler() { 
if (dh == null) { 
dh = new DataHandler(new MimePartDataSource(this)); 
} 
return dh; 
} 
class MimePartDataSource implements DataSource { 
public getInputStream() { 
return MimeUtility.decode( 
getContentStream(), getEncoding()); 
} 
.... <other DataSource methods> 
}

[中]返回此邮件内容的DataHandler。
这里提供的实现大致如下。注意使用getContentStream方法为内容生成字节流。还要注意的是，任何传输解码都是在此方法中自动完成的。

getDataHandler() { 
if (dh == null) { 
dh = new DataHandler(new MimePartDataSource(this)); 
} 
return dh; 
} 
class MimePartDataSource implements DataSource { 
public getInputStream() { 
return MimeUtility.decode( 
getContentStream(), getEncoding()); 
} 
.... <other DataSource methods> 
}
