# The entries in this file map a sparse set of log tag numbers to tag names.

# This is installed on the device, in /system/etc, and parsed by logcat.

#

# Tag numbers are decimal integers, from 0 to 2^31.  (Let's leave the

# negative values alone for now.)

#

# Tag names are one or more ASCII letters and numbers or underscores, i.e.

# "[A-Z][a-z][0-9]_".  Do not include spaces or punctuation (the former

# impacts log readability, the latter makes regex searches more annoying).

#

# Tag numbers and names are separated by whitespace.  Blank lines and lines

# starting with '#' are ignored.

#

# Optionally, after the tag names can be put a description for the value(s)

# of the tag. Description are in the format

#    (<name>|data type[|data unit])

# Multiple values are separated by commas.

#

# The data type is a number from the following values:

# 1: int

# 2: long

# 3: string

# 4: list

#

# The data unit is a number taken from the following list:

# 1: Number of objects

# 2: Number of bytes

# 3: Number of milliseconds

# 4: Number of allocations

# 5: Id

# 6: Percent

# Default value for data of type int/long is 2 (bytes).
