Method Detail

getThis

protected MutableInodeDirectory getThis()

Specified by:

getThis in class MutableInode<MutableInodeDirectory>

this so that the abstract class can use the fluent builder pattern

isMountPoint

public boolean isMountPoint()

Specified by:

isMountPoint in interface InodeDirectoryView

Returns:

true if the inode is a mount point, false otherwise

isDirectChildrenLoaded

public boolean isDirectChildrenLoaded()

Specified by:

isDirectChildrenLoaded in interface InodeDirectoryView
