CTclAccessListCheck

Name

CTclAccessListCheck -- Authenticate against a Tcl List.

Synopsis


#include <TclAccessListCheck.h>
         
 class CTclAccessListCheck {

  CTclAccessListCheck (Tcl_Interp* pInterp, const std::string& rName);

  ~CTclAccessListCheck();

  const CTCLVariable* getVariable();
  const CTCLInterpreter* getInterpreter();
  virtual Bool_t Authenticate(CInteractor& rInteractor);
}

Description

This authenticator is intended to be used in conjunction with Tcl scripts and Tcl servers. The authenticator uses a Tcl variable that contains a list of values. The entity that desires service must present one of the values in that list as its credential.

Public member functions

CTclAccessListCheck (Tcl_Interp* pInterp, const std::string& rName);

Constructs a Tcl Access list authenticator. pInterp is the interpreter handle pointer. This will be wrapped in a CTCLInterpreter object. For more information about the CTCLInterpreter class, see the CTCLInterpreter reference page.

The rName parameter is the name of the TCL variable that contains the list of allowed credentials. Note that the list does not yet need to have been created and, in fact, the variable rName need not yet exist. The variable and list only need to exist at authentication time.

~CTclAccessListCheck();

Releases any resources allocatd by the authenticator as it's destroyed.

const CTCLVariable* getVariable();

Returns a pointer to the CTCLVariable that wraps the Tcl variable. For more information about CTCLVariable objects, see the CTCLVariable reference page.

const CTCLInterpreter* getInterpreter();

Retrieves a pointer to the Tcl Interpreter wrapped in a CTCLInterpreter object.

virtual Bool_t Authenticate(CInteractor& rInteractor);

Uses the rInteractor to fetch a credential from the requestor. If the credential is a member of the list in the Tcl variable with which the authenticator was constructed, this method will return kfTRUE If not, kfFALSE

Types and public data

CTCLInterpreter and CTCLVariable are objects that are part of the Tcl++ library.
