getComparatorValue

public int getComparatorValue()

Get the comparator level for this inventory. Follows the same rules as Container#calcRedstoneLevel()

Returns:

a redstone signal level based on the inventory fullness

invalidateComparatorValue

public void invalidateComparatorValue()

Force a recalculation of the comparator level. Recalculation will be done the next time getComparatorValue() is called. May be necessary to call this if the inventory has been changed indirectly, e.g. by modifying an ItemStack returned from getStackInSlot().
