Method Detail

setDefaultValue

public void setDefaultValue()
Description copied from interface: Attribute
The attribute's value is set so that its getValue() method will not return null.

See Also:
Attribute.setDefaultValue()

setString

public void setString(String value)
Sets the value of this object. The ListenerManager is informed by the method setValue().

Parameters:
value - the new value of this object.

getString

public String getString()
Returns the value of this object.

Returns:
the value of this object.

getValue

public Object getValue()
Returns the value of this attribute, i.e. contained Sting object.

Returns:

doSetValue

protected void doSetValue(Object o)
                   throws IllegalArgumentException
Sets the value of the Attribute. The ListenerManager is informed by the method setValue().

Specified by:

Parameters:
o - the new value of the attribute.
Throws:
IllegalArgumentException - if the parameter has not the appropriate class for this Attribute.

toXMLString

public String toXMLString()
Description copied from interface: Displayable
Returns a well-formed XML string representing the Displayable. The Displayable should be reconstructable via this representation. Therefore it must at least include the type of Displayable (classname) and a representation of its value. PROBABLE FUTURE DESIGN: The Displayables themselves will provide a method to reconstruct their value from the XML representation they provided.

Specified by:
toXMLString in interface Displayable<Object>
Overrides:
toXMLString in class AbstractAttribute
Returns:
string holding an XML representation of this Displayable
