<H3>
Objects of the <STRONG>bulkrole.manager</STRONG> class
</H3>
<P>
The instances of <STRONG>bulkrole.manager</STRONG> class expose a standard
list interface, where list items must be tuples of (<STRONG>address</STRONG>,
<STRONG>data</STRONG>) that represent destination <STRONG>address</STRONG>
(given in <STRONG>socket</STRONG> module notation), outbound <STRONG>data</STRONG>
(string) item to send to remote server on input and source
<STRONG>address</STRONG>, inbound <STRONG>data</STRONG> item on list output as
received from remote server process.
</P>
<P>
The following methods are defined to instances of the
<STRONG>bulkrole.manager</STRONG> class:
</P>
<DL>
<DT><STRONG>dispatch</STRONG>()</DT>
<DD>
<P>
Attempt to send out pending requests (previously committed to class instance
as list members), wait for replies for <STRONG>manager.timeout</STRONG>
seconds and receive those arrived in time.
</P>
<P>
Timed out requests would be represented by a tuple of (None, None) in list
member on list output.
</P>
</DD>
</DL>
<DL>
<DT><STRONG>clear</STRONG>()</DT>
<DD>
<P>
Drop request or response tuples from the list. This method should be invoked
before re-using the same instance of <STRONG>bulkrole.manager</STRONG>
class.
</P>
</DD>
</DL>
<P>
The following methods comprise standard list interface:
</P>
<DL>
<DT><STRONG>append</STRONG>((<STRONG>dst</STRONG>, <STRONG>req</STRONG>))</DT>
<DD>
<P>
Append request tuple (<STRONG>dst</STRONG>, <STRONG>req</STRONG>) to the list
of requests.
</P>
<P>
This method can not be used after the <STRONG>manager.dispatch()</STRONG>
is invoked and the <STRONG>manager.clear()</STRONG> method is used.
</P>
</DD>
</DL>
<DL>
<DT><STRONG>insert</STRONG>(<STRONG>idx</STRONG>, (<STRONG>dst</STRONG>,
<STRONG>req</STRONG>))</DT>
<DT><STRONG>__setitem__</STRONG>(<STRONG>idx</STRONG>, (<STRONG>dst</STRONG>,
<STRONG>req</STRONG>))</DT>
<DD>
<P>
Insert request tuple (<STRONG>dst</STRONG>, <STRONG>req</STRONG>) at
list position <STRONG>idx</STRONG> (integer).
</P>
<P>
This method can not be used after the <STRONG>manager.dispatch()</STRONG>
is invoked and the <STRONG>manager.clear()</STRONG> method is used.
</P>
</DD>
</DL>
<DL>
<DT><STRONG>remove</STRONG>((<STRONG>dst</STRONG>, <STRONG>req</STRONG>))</DT>
<DD>
<P>
Remove the first occurrence of the (<STRONG>dst</STRONG>, <STRONG>req</STRONG>)
request tuple.
</P>
<P>
This method can not be used after the <STRONG>manager.dispatch()</STRONG>
is invoked and the <STRONG>manager.clear()</STRONG> method is used.
</P>
</DD>
</DL>
<DL>
<DT><STRONG>pop</STRONG>([<STRONG>idx</STRONG>])</DT>
<DD>
<P>
Remove from list and return request tuple item at index <STRONG>idx</STRONG>
(default last).
</P>
</DD>
</DL>
<DL>
<DT><STRONG>__getitem__</STRONG>(<STRONG>idx</STRONG>)</DT>
<DD>
<P>
Return request tuple item at index <STRONG>idx</STRONG>.
</P>
</DD>
</DL>
<DL>
<DT><STRONG>count</STRONG>((<STRONG>dst</STRONG>, <STRONG>req</STRONG>))</DT>
<DD>
<P>
Return number of occurrences of request tuple (<STRONG>dst</STRONG>,
<STRONG>req</STRONG>) in the list.
</P>
</DD>
</DL>
<DL>
<DT><STRONG>index</STRONG>((<STRONG>dst</STRONG>, <STRONG>req</STRONG>))</DT>
<DD>
<P>
Return index of first occurrence of request tuple (<STRONG>dst</STRONG>,
<STRONG>req</STRONG>) in the list.
</P>
<P>
This method can not be used after the <STRONG>manager.dispatch()</STRONG>
is invoked and the <STRONG>manager.clear()</STRONG> method is used.
</P>
</DD>
</DL>
<P>
Objects of the <STRONG>bulkrole.manager</STRONG> class have the following
public instance variables:
</P>
<DL>
<DT><STRONG>timeout</STRONG></DT>
<DD>
<P>
Specify for how many seconds to wait for response from remote servers. The
<STRONG>timeout</STRONG> attribute is of floating point type.
</P>
<P>
The default is 1.0 second.
</DD>
</DL>
<DL>
<DT><STRONG>retries</STRONG></DT>
<DD>
<P>
Specify the number of request re-transmissions. The <STRONG>retries</STRONG>
attribute is of integer type.
</P>
<P>
The default is 3 retries.
