Detailed Description
The AgentLog class is an abstract base class representing a log for information that is generated during the run time of an AGENT++ SNMP agent.
A derived class only needs to provide appropriate create_log_entry() and operator+= methods.

pure virtual |
Create a new LogEntry.
- Parameters
-
name - The name of the logging module t - The type of the log entry.
- Returns
- A new instance of LogEntry (or of a derived class).
Implemented in AgentLogImpl.
|
static |
Return the current time as a string, using the current default log object.
(For backward compatibility.)
- Note
- that the user is responsible for deleting the returned string, using delete [].
- Returns
- a string containg the current time.
|
virtual |
Gets the log level for the given log class.
- Returns
- a unsigned char value between 0 and 15
|
inlinevirtual |
Check whether a logging for the given type of LogEntry has to be done or not.
- Parameters
-
type the type of the log entry. The type is composed by logical or the log entry class with a level of 0 up to 15.
- Returns
- TRUE if logging is needed, FALSE otherwise.

|
virtual |
Return the current time as a string.
- Parameters
-
a buffer (of at least 18 characters, for the default method) into which to place a string containg the current time. If no buffer is supplied, a static area is used.
- Returns
- a string containing the current time. Either the supplied buffer or the static area.
Add a LogEntry to the receiver Log.
- Parameters
-
log - A log entry.
- Returns
- The receiver log itself.
Implemented in AgentLogImpl.
|
virtual |
Set a filter on a specified log class.
Only log entries with a level less or equal than the specified level will be logged.
- Parameters
-
logclass - A log entry class.
- See Also
- LogEntry
- Parameters
-
filter - A value between 0 and 15.
