Public Functions

Type	Name
size_t	add_layer (const std::string & layer_name) Add a new layer to the registry.
bool	contains_layer (const std::string & layer_name) const Check if layer exists.
size_t	get_layer_index (const std::string & layer_name) const Get layer index by name.

Detailed Description

Stores metadata about each layer's metadata block for lazy loading. Each layer has its own independent STARMeta block in the file.
