带有 StepRequest.STEP_MIN 参数的 StepRequest
StepRequest with StepRequest.STEP_MIN parameter
在Java调试界面中，带有StepRequest.STEP_MIN参数的StepRequest是什么意思？ https://docs.oracle.com/javase/7/docs/jdk/api/jpda/jdi/com/sun/jdi/request/StepRequest.html Java 文档说 "Step to the next available location"。下一个可用位置是什么？我逐行理解 StepRequest.STEP_LINE 参数到 运行 但什么是 StepRequest.STEP_MIN 参数？当我用这个参数运行时，单行有多个步骤请求，我无法理解。
A sizevalue of StepRequest.STEP_MIN will generate a step event each
time the code index changes. It represents the smallest step size
available and often maps to the instruction level. A size value of
StepRequest.STEP_LINE will generate a step event each time the source
line changes unless line number information is not available, in which
case a STEP_MIN will be done instead
正在查看The class file format#The LineNumberTable
The LineNumberTable attribute is an optional variable-length attribute
in the attributes table of a Code (§4.7.3) attribute. It may be used
by debuggers to determine which part of the Java Virtual Machine code
array corresponds to a given line number in the original source file.
可能 StepRequest 使用代码数组和行号-table 来确定下一步位置。
