Detailed Description

A class to manage the SALOME naming service.

Constructor & Destructor Documentation

SALOME_NamingService::SALOME_NamingService ( )

Default Constructor without ORB reference.

After Default Constructor, one needs to initialize ORB.

See Also: init_orb(CORBA::ORB_ptr orb), SALOME_NamingService(CORBA::ORB_ptr orb)

SALOME_NamingService::SALOME_NamingService ( CORBA::ORB_ptr orb )

Standard Constructor, with ORB reference.

Initializes the naming service root context

Parameters

orb	CORBA::ORB_ptr arguments

SALOME_NamingService::~SALOME_NamingService ( )

virtual

Standard destructor.

The standard destructor does nothing special.

Member Function Documentation

void SALOME_NamingService::init_orb ( CORBA::ORB_ptr orb = 0 )

initializes ORB reference and naming service root context.

Initializes ORB reference and naming service root context. For use after default constructor. If param orb is null, the orb is initialized

Parameters

orb	CORBA::ORB_ptr arguments

void SALOME_NamingService::Register	(	CORBA::Object_ptr	ObjRef,
		const char *	Path
	)		throw (ServiceUnreachable)

Registers a CORBA object reference under a path.

Registers a CORBA object reference under a path. If the path ends with '/', only a directory is created. If the NamingService is out, the exception ServiceUnreachable is thrown.

Parameters

ObjRef	CORBA object reference to associate to the path. To create only a directory, give nil pointer.
Path	A relative or absolute pathname to store the object reference. If the pathname begins with a '/', pathname is taken as an absolute pathname. Else, pathname is taken as a relative path, to current context. Prefer absolute pathname, relative pathname are not safe, when SALOME_NamingService object is shared or use in multithreaded context. If the path ends with '/', only a directory is created.

See Also: Change_Directory(const char* Path), Create_Directory(const char* Path) CORBA::Object_ptr Resolve(const char* Path)

CORBA::Object_ptr SALOME_NamingService::Resolve ( const char * Path ) throw ( ServiceUnreachable)

get the CORBA object reference associated to a name.

get the CORBA object reference associated to a complete name with a path. If the NamingService is out, the exception ServiceUnreachable is thrown

Parameters

Path	pathname. If the pathname begins with a '/', pathname is taken as an absolute pathname. Else, pathname is taken as a relative path, to current context. Prefer absolute pathname, relative pathname are not safe, when SALOME_NamingService object is shared or use in multithreaded context.

Returns: the object reference if it exists under the pathname, or nil reference in other cases.

See Also: Register(CORBA::Object_ptr ObjRef, const char* Path), Change_Directory(const char* Path)

CORBA::Object_ptr SALOME_NamingService::ResolveFirst ( const char * Path ) throw ( ServiceUnreachable)

get the CORBA object reference associated to an uncomplete name.

get the CORBA object reference associated to an uncomplete name with a path. Look for the first occurence of name*. If the NamingService is out, the exception ServiceUnreachable is thrown

Parameters

Path	pathname under the form "/path/name" (Absolute reference !) search the fist reference like "/path(.dir)/name*(.kind)"

Returns: the object reference if found, or nil reference.

See Also: Resolve(const char* Path)

CORBA::Object_ptr SALOME_NamingService::ResolveComponent	(	const char *	hostname,

	)		throw (ServiceUnreachable)

find a component instance from hostname, containername, componentName and number of processors.

find a component instance from hostname, containername, componentName and number of processors. If the NamingService is out, the exception ServiceUnreachable is thrown.

Parameters

hostname	name of the machine on which the component is searched.
containerName	name of the container in which the component is instanciated.
componentName	name of the component we are looking for an existing instance.
nbproc	in case of multi processor machine, container name is suffixed with _nbproc.

Returns: the object reference

std::string SALOME_NamingService::ContainerName ( const char * containerName )

provide a default container name if empty.

the given container name is returned unchanged, unless it is empty.

Parameters

Returns: container name, where empty input is replaced by "FactoryServer", without the path.

See Also: BuildContainerNameForNS(const char *containerName, const char *hostname)

std::string SALOME_NamingService::ContainerName ( const Engines::ContainerParameters & params )

build a container name, given a ContainerParameters struct.

Build a container name with a ContainerParameters struct. In case of multi processor machine, container name is suffixed with number of processors.

Parameters

params struct from which we get container name (may be empty) and number of processors.

Returns: a container name without the path.

See Also: BuildContainerNameForNS(const Engines::ContainerParameters& params, const char *hostname)

std::string SALOME_NamingService::BuildContainerNameForNS	(	const char *	containerName,
		const char *	hostname
	)

build a string representing a container in Naming Service.

Build a string representing the absolute pathname of a container in SALOME_NamingService. This form gives a suffixed containerName in case of multi processor machine.

Parameters

containerName	name of the container in which the component is instanciated.
hostname	name of the host of the container, without domain names.

Returns: the path under the form /Containers/hostname/containerName

See Also: ContainerName(const Engines::MachineParameters& params)

std::string SALOME_NamingService::BuildContainerNameForNS	(	const Engines::ContainerParameters &	params,
		const char *	hostname
	)

build a string representing a container in Naming Service.

Build a string representing the absolute pathname of a container in SALOME_NamingService.

Parameters

params	used as it is, or replaced by FactoryServer if empty.
hostname	name of the host of the container, without domain names.

Returns: the path under the form /Containers/hostname/containerName

See Also: ContainerName(const char *containerName)

int SALOME_NamingService::Find ( const char * name ) throw (ServiceUnreachable)

search a name in current directory.

Search a name in the current directory. after call, the current directory is changed to the directory containing the last occurence of name found. If no occurence found (see return value), current directory remains unchanged.

Parameters

name	the name to search.

Returns: number of occurences found.

See Also: Change_Directory(const char* Path)

bool SALOME_NamingService::Create_Directory ( const char * Path ) throw (ServiceUnreachable)

Creates a directory (context_name)

Creates a directory (context_name) relative to the current directory (current context) or relative to the root directory (root context), if the path given begins with a '/'. If the NamingService is out, the exception ServiceUnreachable is thrown.

Parameters

Path A relative or absolute pathname to store the object reference. If the pathname begins with a '/', pathname is taken as an absolute pathname. Else, pathname is taken as a relative path, to current context. Prefer absolute pathname, relative pathname are not safe, when SALOME_NamingService object is shared or use in multithreaded context.

Returns: true if successfull (creation not strictly garanteed if true, because Register may catch some specific unlikely exception without throw anything — to be corrected —)

See Also: RegisterCORBA::Object_ptr ObjRef, const char* Path)

bool SALOME_NamingService::Change_Directory ( const char * Path ) throw (ServiceUnreachable)

change current directory to the given path

change the current directory to the given path in parameter. Warning: avoid use when the SALOME_NamingService instance is shared by several threads (current context may be modified by another thread). If the path is empty, nothing done return OK. If Path ="/", the current directory changes to the root directory. If the NamingService is out, the exception ServiceUnreachable is thrown.

Parameters

Path	the new current directory

Returns: true if the change succeeded
