Constructor Detail

FsAbstractController

protected FsAbstractController(FsModel model)

Constructs a new file system controller for the given model.

Parameters:

model - the file system model.

Method Detail

getModel

public final FsModel getModel()

Description copied from interface: FsController

Returns the file system model.

Specified by:

getModel in interface FsController

Returns:

The file system model.

getMountPoint

public final FsMountPoint getMountPoint()

Returns the mount point of this (virtual) file system as defined by the model.

Returns:

The mount point of this (virtual) file system as defined by the model.

isMounted

public final boolean isMounted()

Returns the mounted property of the file system model.

Returns:

the mounted property of the file system model.

setMounted

protected final void setMounted(boolean mounted)

Sets the mounted property of the file system model.

Parameters:

mounted - the mounted property of the file system model.

setTime

public boolean setTime(net.java.truecommons.shed.BitField<FsAccessOption> options,
                       FsNodeName name,
                       Map<net.java.truecommons.cio.Entry.Access,Long> times)
                throws IOException

Description copied from interface: FsController

Makes an attempt to set the last access time of all types in the given map for the file system node with the given name. If false is returned or an IOException is thrown, then still some of the last access times may have been set. Whether or not this is an atomic operation is specific to the implementation.

Specified by:

setTime in interface FsController

Parameters:

options - the options for accessing the file system node.

name - the name of the file system node.

times - the access times.

Returns:

true if and only if setting the access time for all types in times succeeded.

Throws:

IOException - on any I/O error.

toString

public String toString()

Returns a string representation of this object for debugging and logging purposes.

Overrides:

toString in class Object

Returns:

A string representation of this object for debugging and logging purposes.
