Method Detail

present

public Presentation present(AttrMap attributes)

Convert this Presentable object into a Presentation, according to the set of attributes provided.

Specified by:

present in interface Presentable

Parameters:

attributes - a map of the desired attributes for this presentation.

Returns:

an appropriate instance of Presentation.

getType

public java.lang.String getType()

This method is primarily for development purposes: it yields the name of the class of the presentable object or, in some cases, the class of the presentable object indirectly referenced. The text returned is canonical class name (subclasses may choose to override this).

Specified by:

getType in interface Presentable

Returns:

a representation of the effective class of this object.

makePresentableInstance

public Presentable makePresentableInstance(Presentation x)

Instance method to convert a Presentation into a Presentable. Ideally, this would be a class method, but such a method cannot be defined in an interface. Nor can it be defined in an abstract class with the intention of overriding it in a subclass. Polymorphism just doesn't work that way.
Therefore, the present value (as in fields) of the instance is essentially ignored - only the methods are important.

Specified by:

makePresentableInstance in interface Presentable

Parameters:

x - a presentation of a number which you want to convert into a number.

Returns:

a number in the form of a Presentable.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
