TabularType ttype = …;
TabularData tdata = new TabularDataSupport(ttype);
Based on 6 examples
public interface TabularData
The TabularData interface specifies the behavior of a specific type of complex open data objects which represent tabular data structures.
Method Summary | |
---|---|
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 CompositeData values (ie rows) from this TabularData instance. |
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(CompositeData value) Returns true if and only if this TabularData instance contains the specified CompositeData value. |
boolean |
Compares the specified obj parameter with this TabularData instance for equality.
|
CompositeData |
Returns the CompositeData value whose index is key, or null if there is no value mapping to key, in this TabularData instance. |
TabularType |
Returns the tabular type describing this TabularData instance. |
int |
hashCode() Returns the hash code value for this TabularData instance.
|
boolean |
isEmpty() Returns true if the number of CompositeData values (ie the number of rows) contained in this TabularData instance is zero. |
Set |
keySet() Returns a set view of the keys (ie the index values) of the values (ie the rows) contained in this instance. |
void |
put(CompositeData value) Adds value to this TabularData instance. |
void |
putAll(CompositeData[] values) Add all the elements in values to this TabularData instance. |
CompositeData |
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 CompositeData values (ie the number of rows) contained in this TabularData instance. |
String |
toString() Returns a string representation of this TabularData instance.
|
Collection |
values() Returns a collection view of the values (ie the rows) contained in this instance. |
Method Detail |

public Object[] calculateIndex(CompositeData value)
value
- the composite data value whose index in this
TabularData instance is to be calculated;
must be of the same composite type as this instance's row type;
must not be null.public void clear()
public boolean containsKey(Object[] key)
key
- the index value whose presence in this TabularData instance is to be tested.public boolean containsValue(CompositeData value)
value
- the row value whose presence in this TabularData instance is to be tested.public boolean equals(Object obj)
TabularData
instance for equality.
Returns true if and only if all of the following statements are true:
TabularData
interface,TabularData
interface.
equals
in class Object
obj
- the object to be compared for equality with this TabularData
instance;true
if the specified object is equal to this TabularData
instance.public CompositeData get(Object[] key)
key
- the key of the row to return.public TabularType getTabularType()
public int hashCode()
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
{@link Object#hashCode() Object.hashCode()}.

public void put(CompositeData value)
value
- the composite data value to be added as a new row to this TabularData instance;
must be of the same composite type as this instance's row type;
must not be null.public void putAll(CompositeData[] values)
values
- the array of composite data values to be added as new rows to this TabularData instance;
if values is null or empty, this method returns without doing anything.public CompositeData remove(Object[] key)
key
- the index of the value to get in this TabularData instance;
must be valid with this TabularData instance's row type definition;
must not be null.public int size()
public String toString()
TabularData
instance.
The string representation consists of the name of the implementing class, and the tabular type of this instance.
