public class HDF5Group
extends HDF5Object

This class is a container for the parameters to the HDF5 Group Object.

HDF5 group is a grouping structure containing instances of zero or more groups or datasets, together with supporting metadata.

Working with groups and group members is similar in many ways to working with directories and files in UNIX. As with UNIX directories and files, objects in an HDF5 file are often described by giving their full (or absolute) path names

For details of the HDF5 libraries, see the HDF5 Documentation at: http://hdf.ncsa.uiuc.edu/HDF5/doc/

loc_id - The file or group identifier..

name - The absolute or relative name of the new group..

Method Detail

setParent

public void setParent(HDF5Group p)

Sets the parent of this group

Parameters:

p - the parent of the HDF5Group

contains

public boolean contains(Object member)

Tests if the specified object is a member of this group.

Parameters:

member - a member

Returns:

true if the specified object is a member of the group; false otherwise.

addMember

public void addMember(Object member)

Adds a new member to the group.

Parameters:

member - the new member to be added to the group

removeMemberAt

public void removeMemberAt(int index)

Deletes the component at the specified index.

removeMember

public boolean removeMember(Object member)

Removes the member from this group

Parameters:

member - the member to be removed.

Returns:

true if the member was a component of this vector; false otherwise.

getMembers

public Vector getMembers()

Returns the members of the group

getParent

public HDF5Group getParent()

Returns the parent of the group

getMemberAt

public Object getMemberAt(int memberIndex)

Returns the member at index memberIndex

Overrides:

toString in class HDF5Object

Returns:

a string representation of this object

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable
