Detailed Description

Class to handle management of on-disk resources.

Member Function Documentation

Resource * Menge::ResourceManager::getResource	(	const std::string &	fileName,
		Resource ()(const std::string &)	reader,
		const std::string &	suffix
	)

static

Retrieve a resource from the manager.

Parameters

fileName	The name of the file associated with the resource.
reader	Pointer to a function for parsing the given file and producing a resource instance.
suffix	The string to append to the file name. This allows different types of resources basedon on the same file resource to be distinguished. It is the burden of the programmer to make sure each type provides a unique suffix, otherwise problems will arise between suffix collisions.

Returns: A pointer to the reference, if it is loaded, NULL otherwise. The caller is responsible for knowing what type of resource it should be and test it using a dynamic-cast.

bool Menge::ResourceManager::removeResource ( Resource * rsrc )

static

Remove the given resource.

Parameters

rsrc	A pointer to the resource to remove.

Returns: True if the pointer is successfully removed, false otherwise. It can fail if the resource doesn't belong to the manager or if the resources reference count is not zero.
