TabularDataSupport instance,
and used to index the rows. Each key contained in this set is an unmodifiable List.
The set is backed by the underlying map of this TabularDataSupport instance,
so changes to the TabularDataSupport instance are reflected in the set, and vice-versa.
The set supports element removal, which removes the
corresponding row from this TabularDataSupport instance, via the Iterator.remove,
Set.remove, removeAll, retainAll, and
clear operations.
It does not support the add or addAll operations

The collection is backed by the underlying map, so changes to the TabularDataSupport instance
are reflected in the collection, and vice-versa.

which removes the corresponding index to row mapping from this TabularDataSupport instance,
via the Iterator.remove, Collection.remove,

TabularDataSupport instance.
Each element in the returned collection is a Map.Entry.
The collection is backed by the underlying map of this TabularDataSupport instance, in
so changes to the TabularDataSupport instance are reflected the collection, and vice-versa.
The collection supports element removal, which removes the corresponding mapping from the map, via the
Iterator.remove, Collection.remove,
removeAll, retainAll, and clear operations.
It does not support the add or addAll operations.
IMPORTANT NOTICE: Do not use the SetValue method of Map.Entry elements contained in the returned
collection view. Doing so would corrupt the index to row mappings contained in this TabularDataSupport instance.
Map.Entrypublic Object clone()
TabularDataSupport instance:
the clone is obtained by calling super.clone(), and then cloning the underlying map.
Only a shallow clone of the underlying map is made, i.e. no cloning of the indexes and row values is made as they are immutable.
Cloneablepublic boolean equals(Object obj)
TabularDataSupport instance for equality.
Returns true if and only if all of the following statements are true:
TabularData interface,TabularData interface.
obj - the object to be compared for equality with this TabularDataSupport instance;
true if the specified object is equal to this TabularDataSupport instance.Object.hashCode(),
Hashtablepublic int hashCode()
TabularDataSupport instance.
The hash code of a TabularDataSupport instance is the sum of the hash codes
of all elements of information used in equals comparisons
(ie: its tabular type and its content, where the content is defined as all the CompositeData values).
This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode()
for any two TabularDataSupport instances t1 and t2,
as required by the general contract of the method
Object.hashCode().
However, note that another instance of a class implementing the TabularData interface
may be equal to this TabularDataSupport instance as defined by equals(java.lang.Object),
but may have a different hash code if it is calculated differently.

Hashtablepublic String toString()
TabularDataSupport instance.
The string representation consists of the name of this class (ie javax.management.openmbean.TabularDataSupport),
the string representation of the tabular type of this instance, and the string representation of the contents
(ie list the key=value mappings as returned by a call to
dataMap.toString()).
