Method Detail

toString

public java.lang.String toString(ValueComponent component)

Converts a ValueComponent to a String.

This method is used by the ValueComponents toString() method.

Parameters:

component - The component to convert.

Returns:

new String

equals

public boolean equals(ValueComponent component1,
                      ValueComponent component2)

Tests if two ValueComponents are identical.

This method is used by the ValueComponents equals(Object) method.

Parameters:

component1 - First component.

component2 - Second component.

Returns:

True if components are identical.

ValueComponent.equals(Object)

compare

public long compare(ValueComponent component1,
                    ValueComponent component2)

Returns the difference between to components.

This method is used by the ValueComponents compareTo(ValueComponent) method.

Parameters:

component1 - First component.

component2 - Second component.

Returns:

The difference between component1 and component2.

ValueComponent.compareTo(ValueComponent)

createValueComponent

public ValueComponent createValueComponent()

Creates a ValueComponent.

This method is used when a ValueComponent needs to be constructed but there is no data available.

Returns:

A newly constructed ValueComponent.

createValueComponent

public ValueComponent createValueComponent(java.lang.Object initialData)
                                    throws ComponentCreationException

Creates a ValueComponent.

This method is used when a ValueComponent needs to be constructed and there is initialization data available.

Parameters:

initialData - The data used to initialize the value component.

Returns:

A newly constructed ValueComponent.

Throws:

ComponentCreationException - The 'initialData' object could not be used to create a valueComponent.

isWithinBounds

public boolean isWithinBounds(ValueComponent comp,
                              long lowerBound,
                              long upperBound)

Checks if a component is within bounds.

This method is called by the ObjectAttribute class when a ValueComponent is being inserted as an element of the ObjectAttribute and the ObjectAttribute is sized.

Parameters:

comp - ValueComponent that needs to be checked.

lowerBound - The lower limit to check.

upperBound - The upper limit to check.

Returns:

True if within the upper and lower limits (inclusive), false otherwise.
