本文整理了Java中org.eclipse.jdt.internal.compiler.ast.Annotation.nullTagBitsFromAnnotationValue()方法的一些代码示例，展示了Annotation.nullTagBitsFromAnnotationValue()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Annotation.nullTagBitsFromAnnotationValue()方法的具体详情如下：
包路径：org.eclipse.jdt.internal.compiler.ast.Annotation
类名称：Annotation
方法名：nullTagBitsFromAnnotationValue

Annotation.nullTagBitsFromAnnotationValue介绍

[英]Convert the value() attribute of @NonNullByDefault into a bitvector a la Binding#NullnessDefaultMASK. This method understands value encodings from source and binary types. pre: null annotation analysis is enabled
[中]将@NonNullByDefault的value（）属性转换为位向量a la Binding#nullnessdaultmask。此方法理解源类型和二进制类型的值编码。前置：已启用空批注分析
