Interface MemoryManagerDelegate

All Known Implementing Classes:

LazyObjectLoader

public interface MemoryManagerDelegate

Sometimes it might not make sense to have a fullblown MemoryManager taking care of some resources, but instead have a delegate that the MemoryManager can make use of. This is the interface for those delegates to implement.

Since:

2.0

Field Summary

static int	REDUCE_AGGRESSIVELY When we're desperately low on memory, we should aggressively reduce memory usage, or else being too timid will simply waste time
static int	REDUCE_SOMEWHAT Since we don't always want to eliminate all caching, when we're low on memory, for performance reasons, this is an indicator to conservatively reduce memory

Method Summary

Library	getLibrary() Get the documents library object.
boolean	reduceMemory(int reductionPolicy) Reduce the amount of memory, as managed by this delegate.
