Update of /cvsroot/monetdb/pathfinder/compiler/include
In directory 23jxhf1.ch3.sourceforge.com:/tmp/cvs-serv9451/compiler/include
Modified Files:
plan_bundle.h
Log Message:
-- Added generic properties-support for plan-bundles. A (algebraic- or
sql-code-) plan-bundle now can have some meta-data attached in the form of an
arbitrary amount of arbitrarily nestable properties (key-value pairs). Such
properties are totally ignored by pathfinder itself, but they can be used to
carry some specific information from the input-data to the output-data.
