TabularData JDK 1.6)

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.

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.

public boolean containsValue (CompositeData value)

Returns true if and only if this TabularData instance contains the specified CompositeData value.

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.

Returns: true if the specified object is equal to this TabularData instance.
Parameters:
- obj - the object to be compared for equality with this TabularData instance;

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().
Returns: the hash code value for this TabularDataSupport instance

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<Object> keySet ()

Returns a set view of the keys (ie the index values) of the CompositeData values (ie the rows) contained in this TabularData instance.

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

public void put (CompositeData value)

Adds value to this TabularData instance.

public void putAll (CompositeData values)

Add all the elements in values to this TabularData instance.

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.
Returns: a string representation of this TabularData instance

public Collection<Object> values ()

Returns a collection view of the CompositeData values (ie the rows) contained in this TabularData instance.

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