Method Summary

Modifier and Type	Method and Description
void	addCacheDependency(SoState state, SoCache cache) Adds a dependency of this instance on another cache instance.
void	addElement(SoElement elt) Adds an element to elements-used list if not already there.
SoElement	getCachedInvalidElement(SoState state) Assuming isValid() returns false, this will return the first cached element that is invalid (auto-caching uses this in its heuristic).
SoElement	getInvalidElement(SoState state) Assuming isValid() returns false, this will return the first state element that is invalid (auto-caching uses this in its heuristic).
void	invalidate() Make this cache invalid.
boolean	isValid(SoState state) Returns true if cache is valid with respect to the given state.
boolean	isValid(SoState state, SoElement elf) Return is the given element is valid True if the element is not monitored.

Constructor Detail

SoCache

public SoCache(SoState state)

Constructor. Takes the state in effect when the cache is used; it is assumed that the state is pushed before the cache is created.

Method Detail

addCacheDependency

public void addCacheDependency(SoState state,
                               SoCache cache)

Adds a dependency of this instance on another cache instance. The default method takes care of adding dependencies from the child cache.

addElement

public void addElement(SoElement elt)

Adds an element to elements-used list if not already there.

isValid

public boolean isValid(SoState state,
                       SoElement elf)

Return is the given element is valid True if the element is not monitored.

invalidate

public void invalidate()

Make this cache invalid.

getInvalidElement

public SoElement getInvalidElement(SoState state)

Assuming isValid() returns false, this will return the first state element that is invalid (auto-caching uses this in its heuristic). Returns NULL if the cache is not invalid because of an element or if the cache is valid.

isValid

public boolean isValid(SoState state)

Returns true if cache is valid with respect to the given state.

getCachedInvalidElement

public SoElement getCachedInvalidElement(SoState state)

Assuming isValid() returns false, this will return the first cached element that is invalid (auto-caching uses this in its heuristic). Returns NULL if the cache is not invalid because of an element or if the cache is valid.
