Class AbstractLazyScope

jOOQ/src/main/java/org/jooq/impl/AbstractLazyScope.java:60–137

Unlike AbstractScope, this implementation lazy initialises its #data() map in order to avoid allocation in very short lived Scope implementations, such as e.g. CacheContext, ConverterContext, GeneratorContext. @author Lukas Eder
