Method Detail

getMembers

@Nullable
public Set<String> getMembers()

Description copied from interface: FsNode

Returns a set of strings with the base names of the members of this directory node or null if and only if this is not a directory node. Whether or not modifying the returned set is supported and the effect on the file system is implementation specific.

Specified by:

getMembers in interface FsNode

Returns:

A set of strings with the base names of the members of this directory node or null if and only if this is not a directory node.

getName

public String getName()

Description copied from interface: FsNode

Returns a string representation of the file system node name.

Specified by:

getName in interface net.java.truecommons.cio.Entry

Specified by:

getName in interface FsNode

Returns:

A string representation of the file system node name.

getSize

public long getSize(net.java.truecommons.cio.Entry.Size type)

Specified by:

getSize in interface net.java.truecommons.cio.Entry

getTime

public long getTime(net.java.truecommons.cio.Entry.Access type)

Specified by:

getTime in interface net.java.truecommons.cio.Entry

getTypes

public net.java.truecommons.shed.BitField<net.java.truecommons.cio.Entry.Type> getTypes()

Description copied from interface: FsNode

Returns a bit field of types implemented by this file system node.

Some file system types allow a node to implement multiple types. For example, a ZIP or TAR file may contain an archive entry with the name foo and a directory archive entry with the name foo/. Yes, this is strange, but sh*t happens! In this case then, a virtual file system should collapse this into one file system node which returns true for both isType(FILE) and isType(DIRECTORY).

Specified by:

getTypes in interface FsNode

Returns:

A bit field of types implemented by this file system node.

input

public final net.java.truecommons.cio.InputSocket<HttpNode> input()

Specified by:

input in interface net.java.truecommons.cio.IoEntry<HttpNode>

input

protected net.java.truecommons.cio.InputSocket<HttpNode> input(net.java.truecommons.shed.BitField<FsAccessOption> options)

isPermitted

public Boolean isPermitted(net.java.truecommons.cio.Entry.Access type,
                           net.java.truecommons.cio.Entry.Entity entity)

Specified by:

isPermitted in interface net.java.truecommons.cio.Entry

isType

public boolean isType(net.java.truecommons.cio.Entry.Type type)

Description copied from interface: FsNode

Returns true if and only if this file system node implements the given type.

Specified by:

isType in interface FsNode

Overrides:

isType in class FsAbstractNode

Parameters:

type - the type to test.

Returns:

true if and only if this file system node implements the given type.
