Multipart

public class Multipart extends Object implements Body
Represents a MIME multipart body (see RFC 2045).A multipart body has a ordered list of body parts. The multipart body also has a preamble and epilogue. The preamble consists of whatever characters appear before the first body part while the epilogue consists of whatever characters come after the last body part.

Constructors Summary
public Multipart()

Methods Summary
public voidaddBodyPart(BodyPart bodyPart)
Adds a body part to the end of the list of body parts.

param
bodyPart the body part.

        bodyParts.add(bodyPart);
        bodyPart.setParent(parent);
public java.util.ListgetBodyParts()
Gets the list of body parts. The list is immutable.

return
the list of BodyPart objects.

        return Collections.unmodifiableList(bodyParts);
private java.lang.StringgetBoundary()
Return the boundory of the parent Entity

return
boundery

        Entity e = getParent();
        ContentTypeField cField = (ContentTypeField) e.getHeader().getField(
                Field.CONTENT_TYPE);
        return cField.getBoundary();
private java.lang.StringgetCharset()

        Entity e = getParent();
        String charString = ((ContentTypeField) e.getHeader().getField(Field.CONTENT_TYPE)).getCharset();
        return charString;
public java.lang.StringgetEpilogue()
Gets the epilogue.

return
the epilogue.

        return epilogue;
public EntitygetParent()

see
org.apache.james.mime4j.message.Body#getParent()

        return parent;
public java.lang.StringgetPreamble()
Gets the preamble.

return
the preamble.

        return preamble;
public java.lang.StringgetSubType()
Gets the multipart sub-type. E.g. alternative (the default) or parallel. See RFC 2045 for common sub-types and their meaning.

return
the multipart sub-type.

        return subType;
public voidsetBodyParts(java.util.List bodyParts)
Sets the list of body parts.

param
bodyParts the new list of BodyPart objects.

        this.bodyParts = bodyParts;
        for (Iterator it = bodyParts.iterator(); it.hasNext();) {
            ((BodyPart) it.next()).setParent(parent);
        }
public voidsetEpilogue(java.lang.String epilogue)
Sets the epilogue.

param
epilogue the epilogue.

        this.epilogue = epilogue;
public voidsetParent(Entity parent)

        this.parent = parent;
        for (Iterator it = bodyParts.iterator(); it.hasNext();) {
            ((BodyPart) it.next()).setParent(parent);
        }
public voidsetPreamble(java.lang.String preamble)
Sets the preamble.

param
preamble the preamble.

        this.preamble = preamble;
public voidsetSubType(java.lang.String subType)

param
subType the sub-type.

        this.subType = subType;
public voidwriteTo(java.io.OutputStream out)

        List bodyParts = getBodyParts();

        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out, CharsetUtil.getCharset(getCharset())),8192);
        
        writer.write(getPreamble() + "\r\n");

        for (int i = 0; i < bodyParts.size(); i++) {
            writer.write(boundary + "\r\n");
            ((BodyPart) bodyParts.get(i)).writeTo(out);
        }
