java.util.Optional<Inode> get(long id,
                              ReadOption option)

Parameters:

option - the options

Returns:

the inode with the given id, if it exists

default java.util.Optional<Inode> get(long id)

Parameters:

id - an inode id

Returns:

the result of get(long, ReadOption) with default option

getChildIds

java.lang.Iterable<java.lang.Long> getChildIds(java.lang.Long inodeId,
                                               ReadOption option)

Returns an iterable for the ids of the children of the given directory.

Parameters:

inodeId - an inode id to list child ids for

option - the options

Returns:

the child ids iterable

getChildIds

default java.lang.Iterable<java.lang.Long> getChildIds(java.lang.Long inodeId)

Parameters:

                                                       ReadOption option)

Returns an iterable for the ids of the children of the given directory.

Parameters:
