public Object[] calculateIndex(CompositeData value)
Calculates the index that would be used in this TabularData instance to refer to the specified
composite data value parameter if it were added to this instance.
This method checks for the type validity of the specified value,
but does not check if the calculated index is already used to refer to a value in this TabularData instance.

 public  void clear()
Removes all CompositeData values (ie rows) from this TabularData instance.

 public boolean containsKey(Object[] key)
Returns true if and only if this TabularData instance contains a CompositeData value
(ie a row) whose index is the specified key. If key is null or does not conform to
this TabularData instance's TabularType definition, this method simply returns false.

 public boolean containsValue(CompositeData value)
Returns true if and only if this TabularData instance contains the specified
CompositeData value. If value is null or does not conform to
this TabularData instance's row type definition, this method simply returns false.

 public boolean equals(Object obj)
Compares the specified obj parameter with this TabularData instance for equality.

Returns true if and only if all of the following statements are true:

obj is non null,
obj also implements the TabularData interface,
their row types are equal
their contents (ie index to value mappings) are equal

This ensures that this equals method works properly for obj parameters which are
different implementations of the TabularData interface.

 

 public CompositeData get(Object[] key)
Returns the CompositeData value whose index is
key, or null if there is no value mapping
to key, in this TabularData instance.

 public TabularType getTabularType()
Returns the tabular type describing this
TabularData instance.

 public int hashCode()
Returns the hash code value for this TabularData instance.

The hash code of a TabularData 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 index to value mappings).

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() .

 public boolean isEmpty()
Returns true if the number of CompositeData
values (ie the number of rows) contained in this
TabularData instance is zero.

 public Set<?> keySet()
Returns a set view of the keys (ie the index values) of the
{@code CompositeData} values (ie the rows) contained in this
{@code TabularData} instance. The returned {@code Set} is a
{@code Set>} but is declared as a {@code Set} for
compatibility reasons. The returned set can be used to iterate
over the keys.

 public  void put(CompositeData value)
Adds value to this TabularData instance.
The composite type of value must be the same as this
instance's row type (ie the composite type returned by
this.getTabularType().getRowType() ), and there must not already be an existing
value in this TabularData instance whose index is the
same as the one calculated for the value to be
added. The index for value is calculated according
to this TabularData instance's TabularType
definition (see TabularType.getIndexNames() ).

 public  void putAll(CompositeData[] values)
Add all the elements in values to this TabularData instance.
If any  element in values does not satisfy the constraints defined in  put ,
or if any two elements in values have the same index calculated according to this TabularData
instance's TabularType definition, then an exception describing the failure is thrown
and no element of values is added,  thus leaving this TabularData instance unchanged.

 public CompositeData remove(Object[] key)
Removes the CompositeData value whose index is key from this TabularData instance,
and returns the removed value, or returns null if there is no value whose index is key.

 public int size()
Returns the number of CompositeData values (ie the
number of rows) contained in this TabularData
instance.

 public String toString()
Returns a string representation of this TabularData instance.

The string representation consists of the name of the implementing class,
and the tabular type of this instance.

 public Collection<?> values()
Returns a collection view of the {@code CompositeData} values
(ie the rows) contained in this {@code TabularData} instance.
The returned {@code Collection} is a {@code Collection}
but is declared as a {@code Collection} for compatibility reasons.
The returned collection can be used to iterate over the values.
