  (change history)

  • Ver.3.2.1 -> 3.2.2 : Fixed the bug that outputs wrong variable types when they contained an annotation; the bug missing a kind of array typed formal parameters.
  • Ver.3.2 -> 3.2.1 : Fixed the bug that outputs wrong scope information on fields declared in enum block.
  • Ver.3.1 -> 3.2 : Fixed the bug that outputs wrong scope information on fields declared in anonymous classes.
  • Ver.3.0 -> 3.1 : Fixed the bug missing a variable name when it was declared with an intialization using another variable.
  • Ver.2.0 -> 3.0 : Extended to process two or more Java source files;
    When "-l" option is specified, this tool accepts a list file instead of a Java source file and processes all Java files described in the list file.
  • Ver.1.2 -> 2.0 : Extended to print variable's type as well.
    The print format was changed to tab-separated format.

Usage

• Options
  • (none): print the source file path, the variable names and their scope information
  • -d : print the abstract syntax tree information as well
• file list
  A text file in which paths of Java source files are described; each line corresponds to each Java source file.

Output format

• file path
• variable's kind (*1)
• variable's name
• variable's type (*2)
• line number of scope starting position
• line number of scope end position

(*1) A variable's kind is one of "F", "M" and "L",
• F: field
• M: method's argument (formal parameter)
• L: local variable
(*2) A variable arity parameter is processed as an array of its type.
