包路径：org.eclipse.jdt.internal.compiler.lookup.BlockScope
类名称：BlockScope
方法名：needBlankFinalFieldInitializationCheck

BlockScope.needBlankFinalFieldInitializationCheck介绍

[英]Returns true if the context requires to check initialization of final blank fields. in other words, it is inside an initializer, a constructor or a clinit
[中]如果上下文需要检查最终空白字段的初始化，则返回true。换句话说，它位于初始值设定项、构造函数或clinit中
