Returns:

the new root

getDefaultValue

protected T getDefaultValue()

Get default node value.

Returns:

the default node value

initializeCache

public void initializeCache(String pathName)

Description copied from interface: StructureCache

Initialize cache.

Specified by:

initializeCache in interface StructureCache<T>

Parameters:

pathName - the path name

putCacheValue

public T putCacheValue(String pathName,
                       T value)

Description copied from interface: StructureCache

Put cache value.

Specified by:

putCacheValue in interface StructureCache<T>

Parameters:

pathName - the path name

value - the value

Returns:

previous value

getCacheValue

public T getCacheValue(String pathName)

Description copied from interface: StructureCache

Get cache value.

Specified by:

getCacheValue in interface StructureCache<T>

Parameters:

pathName - the path name

Returns:

the cache value

getLeaves

public Set<String> getLeaves(String pathName)

Description copied from interface: StructureCache

Get leaves for this path name parameter. Only exact sub path nodes count in. This method should return a mutable Set copy as we intend to modify it in checker processing.

Specified by:

getLeaves in interface StructureCache<T>

Parameters:

pathName - the path name

Returns:

sub-paths nodes or null if no such match yet

invalidateCache

public void invalidateCache(String pathName)

pathName - the path name

removeCache

public void removeCache(String pathName)

Description copied from interface: StructureCache

Remove cache for path name.

Specified by:

removeCache in interface StructureCache<T>

Parameters:

pathName - the path name

flush

public void flush()

Description copied from interface: StructureCache

Flush the cache.

Specified by:

flush in interface StructureCache<T>

getNode

protected org.jboss.deployers.vfs.spi.structure.modified.TreeStructureCache.Node<T> getNode(String path)

Get the path's node.

Parameters:

path - the path

Returns:

node or null if it doesn't exist

initializeNode
