Specified by:

compileAll in interface Dialect

addRule

public void addRule(RuleBuildContext context)

This will add the rule for compiling later on. It will not actually call the compiler

Specified by:

addRule in interface Dialect

 org.drools.util.TypeResolver typeResolver,
 Resource resource)

Specified by:
