Method Detail

getCache

public net.imglib2.cache.volatiles.VolatileCache<Long,net.imglib2.img.cell.Cell<A>> getCache()

setCacheHints

public void setCacheHints(net.imglib2.cache.volatiles.CacheHints cacheHints)

Set hints on how to handle cell requests for this cache. The hints comprise LoadingStrategy, queue priority, and queue order.

Whenever a cell is accessed its data may be invalid, meaning that the cell data has not been loaded yet. In this case, the LoadingStrategy determines when the data should be loaded:

• LoadingStrategy.VOLATILE: Enqueue the cell for asynchronous loading by a fetcher thread, if it has not been enqueued in the current frame already.
• LoadingStrategy.BLOCKING: Load the cell data immediately.
• LoadingStrategy.BUDGETED: Load the cell data immediately if there is enough IoTimeBudget left for the current thread group. Otherwise enqueue for asynchronous loading, if it has not been enqueued in the current frame already.
• LoadingStrategy.DONTLOAD: Do nothing.

If a cell is enqueued, it is enqueued in the queue with the specified queue priority. Priorities are consecutive integers 0 ... n-1, where 0 is the highest priority. Requests with priority i < j will be handled before requests with priority j.

Finally, the queue order determines whether the cell is enqueued to the front or to the back of the queue with the specified priority.

Note, that the queues are cleared whenever a new frame is rendered.

Parameters:

cacheHints - describe handling of cell requests for this cache. May be null, in which case the default hints are restored.
