debug

public void debug(String message,

Log a debug level message

Parameters:

message - message to log

debug

public void debug(String message,
                  Object arg)

Logs by substituting in the argument at the location marked in the message argument by {0}. Additional MessageFormat formatting instructions may be included. Note that this method saves processing time by not building the complete string unless it is necessary; this saves the need for encapsulating many complete logging statements in an "if (log.isDebugEnabled())" block.

Parameters:

message - Message containing "substition marks"

arg - argument to be substitured at the marked location.

debug

public void debug(String message,
                  Object arg0,
                  Object arg1)

Logs by substituting in the arguments at the locations marked in the message argument by {#} (where # is a number). Additional MessageFormat formatting instructions may be included.Note that this method saves processing time by not building the complete string unless it is necessary; this saves the need for encapsulating many complete logging statements in an "if (log.isDebugEnabled())" block.

Parameters:

message - Message containing "substition marks"

arg0 - argument to be substituted at the marked location.

arg1 - argument to be substituted at the marked location.
