debug

public void debug(java.lang.String message,
         java.lang.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 "substitution marks"

arg - argument to be substituted at the marked location.

debug

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.
