Constructor Detail

CanopyCache

public CanopyCache()

Method Detail

clearCache

public void clearCache()

Clear the cache because the canopy has
changed. This ought to destroy the cachedPath.
This must be cleared after every episode!!!!!!

pathFor

public MuSet pathFor(CanopyCrum canopyCrum)

Return the set of all crums from canopyCrum
(inclusive) to the top of canopyCrum's canopy.

rootFor

public CanopyCrum rootFor(CanopyCrum bertCrum)

Return the crum at the top of canopyCrum's canopy.

updateCacheForParent

public void updateCacheForParent(CanopyCrum childCrum,
                                 CanopyCrum parentCrum)

If the cache contains childCrum it must be made
to contain childCrum's new parent: parentCrum.
Also update CachedRoot.

updateCacheFor

public void updateCacheFor(CanopyCrum canopyCrum)

If the cache contains canopyCrum, it must be updated
because canopyCrum has new parents. For now, just
invalidate the cache.

actualHashForEqual

public int actualHashForEqual()

Overrides:

actualHashForEqual in class Heaper

make

public static Heaper make()
