Method Detail

getProtectedTileComputers

public List<MapTileAreaComputer> getProtectedTileComputers()

Since:

6.0.2

getProtectedTileContainers

public List<MapTileContainer> getProtectedTileContainers()

Since:

6.0.2

setAutoEnsureCapacity

public void setAutoEnsureCapacity(boolean pAutoEnsureCapacity)

Since:

6.0.3

setStressedMemory

public void setStressedMemory(boolean pStressedMemory)

Since:

6.0.4 When true, all the tiles in the cache that eventually don't belong here are removed asap. When false, we will still remove tiles that do not belong in the cache anymore, but not necessarily all of them: only the amount we need in order to fit the cache size. Should be set to true when you have small memory and big tiles in order to avoid OutOfMemoryException. Should be set to false for better performances.

ensureCapacity

public boolean ensureCapacity(int pCapacity)

getMapTile
