Constructor Detail

SystemLogChute

public SystemLogChute()
Method Detail

init

public void init(RuntimeServices rs)
Description copied from interface: LogChute
Initializes this LogChute.

Specified by:
init in interface LogChute

toLevel

protected int toLevel(String level)

getPrefix

protected String getPrefix(int level)

log

public void log(int level,
                String message)
Logs messages to either std.out or std.err depending on their severity.

Specified by:
log in interface LogChute
Parameters:
level - severity level
message - complete error message

log

public void log(int level,
                String message,
                Throwable t)
Logs messages to the system console so long as the specified level is equal to or greater than the level this LogChute is enabled for. If the level is equal to or greater than LogChute.ERROR_ID, messages will be printed to System.err. Otherwise, they will be printed to System.out. If a java.lang.Throwable accompanies the message, it's stack trace will be printed to the same stream as the message.

Specified by:
log in interface LogChute
Parameters:
level - severity level
message - complete error message
t - the java.lang.Throwable

write

protected void write(PrintStream stream,
                     String prefix,
                     String message,
                     Throwable t)

setEnabledLevel

public void setEnabledLevel(int level)
Set the minimum level at which messages will be printed.


getEnabledLevel

public int getEnabledLevel()
Returns the current minimum level at which messages will be printed.


setSystemErrLevel

public void setSystemErrLevel(int level)
Set the minimum level at which messages will be printed to System.err instead of System.out.


getSystemErrLevel

public int getSystemErrLevel()
Returns the current minimum level at which messages will be printed to System.err instead of System.out.


isLevelEnabled

public boolean isLevelEnabled(int level)
This will return true if the specified level is equal to or higher than the level this LogChute is enabled for.

Specified by:
isLevelEnabled in interface LogChute
Returns:
