                        PojoPathMode mode,
                        String pojoPath)

The constructor for no caching.

Parameters:

rootPath - is the PojoPath with the initial Pojo.

mode - is the mode that determines how to deal null values.

pojoPath - is the pojo-path.

PojoPathState

protected PojoPathState(AbstractPojoPathNavigator.CachingPojoPath rootPath,
                        PojoPathMode mode,
                        String pojoPath,
                        Map<String,AbstractPojoPathNavigator.CachingPojoPath> cache)

Method Detail

getCachedPath

public AbstractPojoPathNavigator.CachingPojoPath getCachedPath(String currentPojoPath)

This method gets the AbstractPojoPathNavigator.CachingPojoPath from the cache.

Parameters:

currentPojoPath - is the PojoPath to lookup.

Returns:

the cached AbstractPojoPathNavigator.CachingPojoPath or null if NOT (yet) cached.

setCachedPath

public void setCachedPath(String currentPojoPath,
                          AbstractPojoPathNavigator.CachingPojoPath evaluatedPojoPath)

This method stored a AbstractPojoPathNavigator.CachingPojoPath in the cache. This method will do nothing if this state is disabled.

Parameters:

currentPojoPath - is the PojoPath leading to the given pojo.

evaluatedPojoPath - is the AbstractPojoPathNavigator.CachingPojoPath that has been evaluated and should be cached.

removeCachedPath

public void removeCachedPath(String currentPojoPath)

This method removes a AbstractPojoPathNavigator.CachingPojoPath from the cache. This method will do nothing if this state is disabled.

Parameters:

currentPojoPath - is the PojoPath to purge from the cache.

getRootPath

public AbstractPojoPathNavigator.CachingPojoPath getRootPath()

Returns:

the rootPath

getMode

public PojoPathMode getMode()

This method gets the PojoPathMode that determines how to deal with null-values.

Returns:

the mode.

getPojoPath

public String getPojoPath()

Returns:

the initial pojoPath

isGetType

public boolean isGetType()

This method determines if we have been invoked from getType.

Returns:

true if invoked via getType, false if invoked from get or set.

isCachingDisabled

public boolean isCachingDisabled()

This method determines if this cache has been disabled.

Returns:

true if this cache is disabled, false otherwise.

setCachingDisabled

public void setCachingDisabled()

This method disables further caching.
