      1 # The entries in this file map a sparse set of log tag numbers to tag names.
      2 # This is installed on the device, in /system/etc, and parsed by logcat.
      3 #
      4 # Tag numbers are decimal integers, from 0 to 2^31.  (Let's leave the
      5 # negative values alone for now.)
      6 #
      7 # Tag names are one or more ASCII letters and numbers or underscores, i.e.
      8 # "[A-Z][a-z][0-9]_".  Do not include spaces or punctuation (the former
      9 # impacts log readability, the latter makes regex searches more annoying).
     10 #
     11 # Tag numbers and names are separated by whitespace.  Blank lines and lines
     12 # starting with '#' are ignored.
     13 #
     14 # Optionally, after the tag names can be put a description for the value(s)
     15 # of the tag. Description are in the format
     16 #    (<name>|data type[|data unit])
     17 # Multiple values are separated by commas.
     18 #
     19 # The data type is a number from the following values:
     20 # 1: int
     21 # 2: long
     22 # 3: string
     23 # 4: list
     24 #
     25 # The data unit is a number taken from the following list:
     26 # 1: Number of objects
     27 # 2: Number of bytes
     28 # 3: Number of milliseconds
     29 # 4: Number of allocations
     30 # 5: Id
     31 # 6: Percent
     32 # Default value for data of type int/long is 2 (bytes).
