|
<B><TT>DwBodyPart</TT></B> represents a <I>body part</I>, as described in
|
|
RFC-2045 and RFC-2046. A body part is an <I>entity</I>, so it has a collection
|
|
of headers and a <I>body</I>. A body part is different from a <I>message</I>
|
|
in that a body part is part of a multipart body.
|
|
<P>
|
|
In MIME++, a <B><TT>DwBodyPart</TT></B> is a subclass of
|
|
<B><TT><A HREF="entity.html">DwEntity</A></TT></B>; therefore, it tqcontains
|
|
both a <B><TT><A HREF="headers.html">DwHeaders</A></TT></B> object and a
|
|
<B><TT><A HREF="body.html">DwBody</A></TT></B> object, and it is contained
|
|
in a multipart <B><TT>DwBody</TT></B> object.
|
|
<P>
|
|
As with <B><TT><A HREF="message.html">DwMessage</A></TT></B>, most of the
|
|
functionality of <B><TT>DwBodyPart</TT></B> is implemented by the abstract
|
|
class <B><TT>DwEntity</TT></B>.

The first constructor is the default constructor, which sets the
|
|
<B><TT>DwBodyPart</TT></B> object's string representation to the empty string
|
|
and sets its parent to <B><TT>NULL</TT></B>.
|
|
<P>
|
|
The second constructor is the copy constructor, which performs a deep copy
|
|
of <B><TT>aPart</TT></B>. The parent of the new
|
|
<B><TT>DwBodyPart</TT></B> object is set to <B><TT>NULL</TT></B>.
|
|
<P>
|
|
The third constructor copies <B><TT>aStr</TT></B> to the
|
|
<B><TT>DwBodyPart</TT></B> object's string representation and sets
|
|
<B><TT>aParent</TT></B> as its parent. The virtual member function
|
|
<B><TT>Parse()</TT></B> should be called immediately after this constructor
|
|
in order to parse the string representation. Unless it is
|
|
<B><TT>NULL</TT></B>, <B><TT>aParent</TT></B> should point to an object of
|
|
a class derived from <B><TT>DwBody</TT></B>.
|

<FONT COLOR="teal"><B> const DwBodyPart& <A NAME="op_eq">operator =</A>

<P>
|

This is the assignment operator, which performs a deep copy of
|
|
<B><TT>aPart</TT></B>. The parent node of the <B><TT>DwBodyPart</TT></B>
|
|
object is not changed.

This virtual function, inherited from <B><TT>DwMessageComponent</TT></B>,
|
|
creates a new <B><TT>DwBodyPart</TT></B> on the free store that has the same
|
|
value as this <B><TT>DwBodyPart</TT></B> object. The basic idea is that of
|
|
a virtual copy constructor.

Creates a new <B><TT>DwBodyPart</TT></B> on the free store. If the static
|
|
data member <B><TT>sNewBodyPart</TT></B> is <B><TT>NULL</TT></B>, this member
|
|
function will create a new <B><TT>DwBodyPart</TT></B> and return it. Otherwise,
|
|
<B><TT>NewBodyPart()</TT></B> will call the user-supplied function pointed
|
|
to by <B><TT>sNewBodyPart</TT></B>, which is assumed to return an object
|
|
from a class derived from <B><TT>DwBodyPart</TT></B>, and return that object.

This member function returns the next <B><TT>DwBodyPart</TT></B> object following
|

this <B><TT>DwBodyPart</TT></B> in the list of <B><TT>DwBodyPart</TT></B>

objects contained in a multipart <B><TT>DwBody</TT></B>.

This advanced function sets <B><TT>aPart</TT></B> as the next
|
|
<B><TT>DwBodyPart</TT></B> object following this
|
|
<B><TT>DwBodyPart</TT></B> in the list of <B><TT>DwBodyPart</TT></B> objects
|
|
contained in a multipart <B><TT>DwBody</TT></B>. Since
|
|
<B><TT>DwBody</TT></B> tqcontains a member function for adding a
|
|
<B><TT>DwBodyPart</TT></B> object to its list, this function should be avoided
|
|
for most applications.

This virtual function, inherited from <B><TT>DwMessageComponent</TT></B>,
|
|
prints debugging information about this object to <B><TT>aStrm</TT></B>.
|

It will also call <B><TT>PrintDebugInfo()</TT></B> for any of its child

components down to a level of <B><TT>aDepth</TT></B>.
