Examples of org.drools.compiler.compiler.PackageBuilderConfiguration

org.drools.compiler.compiler.PackageBuilderConfiguration
This class configures the package compiler. Dialects and their DialectConfigurations are handled by the DialectRegistry Normally you will not need to look at this class, unless you want to override the defaults. This class is not thread safe and it also contains state. Once it is created and used in one or more PackageBuilders it should be considered immutable. Do not modify its properties while it is being used by a PackageBuilder. drools.dialect.default = drools.accumulate.function. = drools.evaluator. = drools.dump.dir = drools.classLoaderCacheEnabled = true|false default dialect is java. Available preconfigured Accumulate functions are: drools.accumulate.function.average = org.kie.base.accumulators.AverageAccumulateFunction drools.accumulate.function.max = org.kie.base.accumulators.MaxAccumulateFunction drools.accumulate.function.min = org.kie.base.accumulators.MinAccumulateFunction drools.accumulate.function.count = org.kie.base.accumulators.CountAccumulateFunction drools.accumulate.function.sum = org.kie.base.accumulators.SumAccumulateFunction drools.parser.processStringEscapes = true|false drools.problem.severity. = ERROR|WARNING|INFO
