Method Detail

setLogStream

public static void setLogStream(java.io.PrintStream logStream)

Sets the log output to an other print stream. The default pre-configured print stream is System.out .

Parameters:

logStream - print stream for the log output or null, to disable the log output.

getLogStream

public static java.io.PrintStream getLogStream()

Returns the current print stream for the log output

Returns:

current print stream for the log output or null, if the log output is disabled

log

public static void log()

Writes an empty line to the log output. However, the prefixes "tread-name" and "date/time" will always be written.

log

public static void log(java.lang.String msg)

Writes a text line to the log output.

Parameters:

msg - text line to write

log

public static void log(java.lang.StringBuffer msg)

Writes a string buffer to the log output.

Parameters:

msg - string buffer to write

log

public static void log(java.util.Vector msgVector)

Writes a Vector of Type java.lang.String to the log output. Each element of the Vector will be written as a separate line.

Parameters:

msgVector - Vector of Type java.lang.String to write

log

public static void log(java.lang.String preComment,
                       java.lang.Exception e)

Writes a stack trace of an exception to the log output.

Parameters:

preComment - inserts a text string at the start of every line of the stack trace. You may pass null or an empty string to disable this behavior.

e - exception whose stack trace will be written

log

public static void log(byte[] binaryData)

Writes binary data as ASCII/TEXT to the log output. Conversions:

• bytes from the range 32..126 are written as ASCII text chars
• byte 10 will be written as "<LF>"
• byte 13 will be written as "<CR>"
• all other byte-values will be written as "(ASCII number)"

Parameters:

binaryData - binary data to write as ASCII/TEXT dump
