Detailed Description

This is a NULL Action. You can use it to probe the overall architecture.

We derive this class from OSM_Action_Base so we can use it automatically within the Osmius monitoring or recollecting framework. We only have to implement the execute action using our base clase execute() method interface, and do the same with check_cmd_line() method.

Member Function Documentation

int OSM_ACT_LinuxNull::execute ( const ACE_TCHAR *  cmd_line,
const int  cmd_len,
const int  timeout,
ACE_TCHAR *  val_text,
int &  val_len,
int &  value 
) [virtual]

Executes the action using the command line and returns the associated text and value.

Parameters:
cmd_line Input - Command line used to execute this action.
cmd_len Input - Command line length.
timeout Input - Wait timeout seconds before aborting execution.
val_text Output - Text of the resulting action.
val_len Output - Text length.
value Output - Final value of the action.
Return values:
-1 in case of error. 0 for success.

Implements OSM_Action_Base.

Definition at line 561 of file osm_ag_linux.cpp.

int OSM_ACT_LinuxNull::check_cmd_line ( const ACE_TCHAR *  cmd_line,
const int  cmd_len 
) [virtual]

Checks the command line. You should overwrite this method to handle issues like semantic and sintactic checking or security stuff. E.g. You could return error if your SQL string contains the words UPDATE, DELETE or INSERT.

Parameters:
cmd_line Input - Command line used to execute this action.
cmd_len Input - Command line length.
Return values:
-1 in case of error. 0 for success.

Reimplemented from OSM_Action_Base.

void OSM_Action_Base::set_name ( const ACE_TCHAR *  nm  )  [inline, inherited]

Sets the name of the action.

Parameters:
nm Input - Name.

void OSM_Action_Base::instance ( OSM_Instance_Base ins  )  [inline, inherited]

Sets the instance.

Parameters:
ins Input - Instance pointer.

Definition at line 126 of file osm_ag_insmanager.h.

const OSM_Instance_Base* OSM_Action_Base::instance ( void   )  const [inline, inherited]

Return a pointer to the instance.

Definition at line 134 of file osm_ag_insmanager.h.

void OSM_Action_Base::ev_parameters ( const ACE_TCHAR *  param  )  [inline, inherited]

Parameters:
param Input - Parameters (command line like).

const ACE_TCHAR* OSM_Action_Base::ev_parameters ( void   )  const [inline, inherited]

Return pointer to parameters.

Definition at line 152 of file osm_ag_insmanager.h.

const ACE_TCHAR* OSM_Action_Base::name ( void   )  const [inline, inherited]

Return pointer to my name.
