java.lang.Objectorg.drools.io.RuleBaseLoader
public final class RuleBaseLoader
Convenience methods for loading a RuleBase
, as well as lower level calls
for building up a rule base from RuleSets.
Note that the loadXXX static helper methods work directly off DRL, building/compiling behind the scenes.
The addXXX methods generally work with pre compiled rules binaries (DDJ's as they are known).
The RuleBaseLoader
provides convenience methods for loading
RuleBase
s from streams. RuleBaseLoader
is
thread-safe and as such may be used to build multiple RuleBase
s
simultaneously by multiple threads.

|
void |
addFromRuleSetLoader(RuleSetLoader ruleSetLoader)
Adds to the rulebase from a RuleSetLoader instance. |
void |
addFromRuleSetLoader(RuleSetLoader[] ruleSetLoaders)
Loads a RuleBase using several URLs, using the DefaultConflictResolver. |
void |
addFromUrl(java.net.URL url)
Loads a RuleBase from a URL using the given ConflictResolver The URL must be to a DDJ compiled resource, or a conf file pointing to the DDJ compiled rules. |
void |
addFromUrl(java.net.URL[] urls)
Loads a RuleBase from several URLS, merging them and using the specified ConflictResolver. |
RuleBase |
buildRuleBase()
This will return a rulebase based on the added rulesets. |
