Constructor Summary

Constructors

Constructor	Description
TabularDataSupport(TabularType tabularType)	Creates an empty TabularDataSupport instance whose open-type is tabularType, and whose underlying HashMap has a default initial capacity (101) and default load factor (0.75).
TabularDataSupport(TabularType tabularType, int initialCapacity, float loadFactor)	Creates an empty TabularDataSupport instance whose open-type is tabularType, and whose underlying HashMap has the specified initial capacity and load factor.

Method Summary

Modifier and Type	Method	Description
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.
void	clear()	Removes all rows from this TabularDataSupport instance.
Object	clone()	Returns a clone of this TabularDataSupport instance: the clone is obtained by calling super.clone(), and then cloning the underlying map.
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.
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.
boolean	containsValue(Object value)	Returns true if and only if this TabularData instance contains the specified value.
boolean	containsValue(CompositeData value)	Returns true if and only if this TabularData instance contains the specified CompositeData value.
Set<Map.Entry<Object,Object>>	entrySet()	Returns a collection view of the index to row mappings contained in this TabularDataSupport instance.
boolean	equals(Object obj)	Compares the specified obj parameter with this TabularDataSupport instance for equality.
Object	get(Object key)	This method simply calls get((Object[]) key).
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.
TabularType	getTabularType()	Returns the tabular type describing this TabularData instance.
int	hashCode()	Returns the hash code value for this TabularDataSupport instance.
boolean	isEmpty()	Returns true if this TabularDataSupport instance contains no rows.
Set<Object>	keySet()	Returns a set view of the keys contained in the underlying map of this TabularDataSupport instance used to index the rows.
Object	put(Object key, Object value)	This method simply calls put((CompositeData) value) and therefore ignores its key parameter which can be null.
void	put(CompositeData value)	Adds value to this TabularData instance.
void	putAll(Map<?,?> t)	Add all the values contained in the specified map t to this TabularData instance.
void	putAll(CompositeData[] values)	Add all the elements in values to this TabularData instance.
Object	remove(Object key)	This method simply calls remove((Object[]) key).
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.
int	size()	Returns the number of rows in this TabularDataSupport instance.
String	toString()	Returns a string representation of this TabularDataSupport instance.
Collection<Object>	values()	Returns a collection view of the rows contained in this TabularDataSupport instance.
