Examples of com.celum.dbtool.installer.VelocityInterceptor

com.celum.dbtool.installer.VelocityInterceptor
This inteceptor impl. is responsible for templating. Means placeholders in SQL will be replaced by real values and modified SQL is then moved to decorated strategy where is processed. example: Map values = ...; values.put("user", "mickeymouse"); ... VelocityDecorator strategy = VelocityDecorator.decorate(new ListParser(), values); List sql = Sql .loadScriptFromStream(is) .interceptingSqlWith(new VelocityInterceptor(values)) .viaStrategy(new ListParser()) .returnListOfQueries(); @author Zdenko Vrabel (zdenko.vrabel@celum.com)
