Class MIMEPart

  • All Implemented Interfaces:
    Closeable, AutoCloseable
    public class MIMEPart
extends Object
implements Closeable
    Represents an attachment part in a MIME message. MIME message parsing is done lazily using a pull parser, so the part may not have all the data. read() and readOnce() may trigger the actual parsing the message. In fact, parsing of an attachment part may be triggered by calling read() methods on some other attachment parts. All this happens behind the scenes so the application developer need not worry about these details.

    • Method Detail

      • read

        public InputStream read()
        Can get the attachment part's content multiple times. That means the full content needs to be there in memory or on the file system. Calling this method would trigger parsing for the part's data. So do not call this unless it is required(otherwise, just wrap MIMEPart into a object that returns InputStream for e.g DataHandler)
        Returns:
        data for the part's content

      • close

        public void close()
        Cleans up any resources that are held by this part (for e.g. deletes the temp file that is used to serve this part's content). After calling this, one shouldn't call read() or readOnce()
        Specified by:
        close in interface AutoCloseable
        Specified by:
        close in interface Closeable

      • readOnce

        public InputStream readOnce()
        Can get the attachment part's content only once. The content will be lost after the method. Content data is not be stored on the file system or is not kept in the memory for the following case: - Attachement parts contents are accessed sequentially In general, take advantage of this when the data is used only once.
        Returns:
        data for the part's content

      • moveTo

        public void moveTo​(File f)

      • getContentId

        public String getContentId()
        Returns Content-ID MIME header for this attachment part
        Returns:
        Content-ID of the part

      • getContentTransferEncoding

        public String getContentTransferEncoding()
        Returns Content-Transfer-Encoding MIME header for this attachment part
        Returns:
        Content-Transfer-Encoding of the part

      • getContentType

        public String getContentType()
        Returns Content-Type MIME header for this attachment part
        Returns:
        Content-Type of the part

      • getHeader

        public List<String> getHeader​(String name)
        Return all the values for the specified header. Returns null if no headers with the specified name exist.
        Parameters:
        name - header name
        Returns:
        list of header values, or null if none

      • getAllHeaders

        public List<? extends Header> getAllHeaders()
        Return all the headers
        Returns:
        list of Header objects

      • isClosed

        public boolean isClosed()
        Return true if this part has already been closed, false otherwise.
        Returns:
        true if this part has already been closed, false otherwise.
