Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
int	GetRefCount () const noexcept
	Get the reference counter of this object.
void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
virtual void	Delete () const
	Memory deallocator for transient classes.

Static Public Member Functions
static void	GetResourcePath (TCollection_AsciiString &aPath, const char *const aName, const bool isUserDefaults)
	Gets the resource file full path by its name. If corresponding environment variable is not set or file doesn't exist returns empty string.

	Returns a type descriptor about this object.
static const opencascade::handle< Standard_Type > &	get_type_descriptor ()
	Returns type descriptor of Standard_Transient class.

Constructor & Destructor Documentation

Resource_Manager() [1/3]

Resource_Manager::Resource_Manager	(	const char *const	aName,
		const bool	Verbose = false )

Create a Resource manager. Attempts to find the two following files: $CSF_aNameDefaults/aName $CSF_aNameUserDefaults/aName and load them respectively into a reference and a user resource structure.

If CSF_ResourceVerbose defined, seeked files will be printed.

FILE SYNTAX The syntax of a resource file is a sequence of resource lines terminated by newline characters or end of file. The syntax of an individual resource line is:

Resource_Manager() [2/3]

Resource_Manager::Resource_Manager

(

)

Create an empty Resource manager.

		const TCollection_AsciiString &	theDefaultsDirectory,
		const TCollection_AsciiString &	theUserDefaultsDirectory,
		const bool	theIsVerbose = false )

Create a Resource manager.

Parameters

[in]	theName	description file name
