Method Detail

getDimension

GridDimension getDimension()

Returns the dimension for this grid.

getDef

GridBrowserDef getDef()

Returns the definition that controls the behavior of this instance.

getElementsAtSameIntersection

java.util.Iterator<Element> getElementsAtSameIntersection(Element e)

Returns the elements, which shares the same intersection point. E.g. the row object, and column object are identical.

Parameters:

e - The element

Returns:

An iterator.

getElementsWithSameConnectionId

java.util.Iterator<Element> getElementsWithSameConnectionId(Element e)

Returns all the elements, which has the same connection id as the specified element

Parameters:

e - The element

Returns:

An iterator.

getElementWithId

Element getElementWithId(long id)

Returns the element that has the specified id. If such element does not exist within this model, null is returned.

getIntersection

Intersection getIntersection(Element e)

getElementFor

Element getElementFor(TableData row,
                    TableData col)

getElements

java.util.Iterator<Element> getElements()

Returns the elements, from left->right, top->bottom.

validate

void validate(Environment env)
              throws TVCException

This method should be called to validate the grid when the isValid() returns false. Exactly what is validated is up to the implementing classes to decide.

Throws:

TVCException

isValid

boolean isValid()
                throws TVCException

This method returns true if the grid is valid. An invalid grid has to be validated before displayed.

Throws:

TVCException

invalidate

void invalidate()

This method can be used to invalidate the grid and force a revalidation by calling validate(Environment).

getGridAxes

GridAxes getGridAxes()

Returns the GridAxes instance, which holds the data on the row and col axis.

getElementPosition

GridPosition getElementPosition(Element element)

Returns the position of an element within the grid.

Parameters:

element - The element

Returns:

The position
