[ Up: Operation Reference ]

The MeshModelDiskCache operation is used to cache MeshModelInterface data, allowing downstream processing to occur without reloading data from sources. The cache has a fixed item limit, which if exceeded will cause the cache to write the least recently used item to disk. Optionally, the cache can be persistent, allowing data to be stored between sessions. Mesh data is serialized using the Workspace Binary Mesh (wbm) format.

Default label: "Mesh model disk cache"
Member of plug-in: Mesh
Catalogue path: Mesh

Inputs:
Clear cache	CSIRO::DataExecution::Dependency	When triggered, clears the cache contents (including serialized data).
Data location	QString	Where, on disk, to write serialized mesh data when the cache limit is exceeded.
Persistant	bool	If enabled, Workspace will not clean up the target location when the operation is deleted, or when the workspace is closed.
Item limit	int	The maximum number of items that can be stored in-memory in the cache. Once this limit is exceeded, the least-recently used item in the cache will be written to disk. When this item is needed again, it will be returned from the cache.
Key	QString	The key associated with the Mesh model being added to the cache / retrieved from the cache.
Mesh model	CSIRO::Mesh::MeshModelInterface	The mesh model to add to the cache. NOTE: If an item already exists in the cache with the same key, this input will NOT be brought up-to-date.
Outputs:
Mesh model	CSIRO::Mesh::MeshModelInterface
