event.logtags revision 53367585956dd5a4da37e388e5a32ce577d8174a 
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).
33#
34# TODO: generate ".java" and ".h" files with integer constants from this file.
35
36# These are used for testing, do not modify without updating
37# tests/framework-tests/src/android/util/EventLogFunctionalTest.java.
