构造方法详细信息

MessageHeaders

public MessageHeaders()
               throws MessagingException

Construct a MessageHeaders object.

抛出：

MessagingException

MessageHeaders

public MessageHeaders(InputStream is)
               throws MessagingException

Constructs a MessageHeaders object from the given InputStream.

参数：

is - InputStream

抛出：

MessagingException

MessageHeaders

public MessageHeaders(InternetHeaders headers)
               throws MessagingException

Constructs a MessageHeaders object using the given InternetHeaders.

参数：

headers - InternetHeaders to use

抛出：

MessagingException

方法详细信息

getSize

public int getSize()

Return the size of this message. Always returns zero.

指定者：

接口 Part 中的 getSize

覆盖：

类 MimeMessage 中的 getSize

返回：

size of content in bytes

getInputStream

public InputStream getInputStream()

从类 MimeMessage 复制的描述

Return a decoded input stream for this Message's "content".

This implementation obtains the input stream from the DataHandler, that is, it invokes getDataHandler().getInputStream().

指定者：

接口 Part 中的 getInputStream

覆盖：

类 MimeMessage 中的 getInputStream

返回：

an InputStream

另请参见：

MimeMessage.getContentStream(), DataHandler.getInputStream()

getContentStream

protected InputStream getContentStream()

从类 MimeMessage 复制的描述

Produce the raw bytes of the content. This method is used during parsing, to create a DataHandler object for the content. Subclasses that can provide a separate input stream for just the message content might want to override this method.

This implementation returns a SharedInputStream, if contentStream is not null. Otherwise, it returns a ByteArrayInputStream constructed out of the content byte array.

覆盖：

类 MimeMessage 中的 getContentStream

另请参见：

MimeMessage.content

setDataHandler

public void setDataHandler(DataHandler dh)
                    throws MessagingException

Can't set any content for a MessageHeaders object.

指定者：

接口 Part 中的 setDataHandler

覆盖：

类 MimeMessage 中的 setDataHandler

参数：

dh - The DataHandler for the content.

抛出：

MessagingException - always
