Detailed Description

This is an ObjectCalcer that keeps an ObjectImp, and never calculates a new one.

It is a trivial, but very useful ObjectCalcer. It is used often in Kig, for holding data to be used by other ObjectCalcer's.

Constructor & Destructor Documentation

ObjectConstCalcer::ObjectConstCalcer

(

ObjectImp *

imp

)

Construct a new ObjectConstCalcer with the given imp as the stored ObjectImp.

This class takes ownership of the imp you pass it, it should have been constructed using new, and this class is responsible for deleting it.

Member Function Documentation

void ObjectConstCalcer::calc ( const KigDocument &  )

virtual

Makes the ObjectCalcer recalculate its ObjectImp from its parents.

Implements ObjectCalcer.

Definition at line 70 of file object_calcer.cc.

const ObjectImp * ObjectConstCalcer::imp ( ) const

virtual

Returns the ObjectImp of this ObjectCalcer.

Implements ObjectCalcer.

Definition at line 65 of file object_calcer.cc.

const ObjectImpType * ObjectConstCalcer::impRequirement ( ObjectCalcer *  o, const std::vector< ObjectCalcer * > &  os  ) const

virtual

An ObjectCalcer expects its parents to have an ObjectImp of a certain type.

This method returns the ObjectImpType that o should have. os is a list of all the parents in order, and o is part of it. This method will return the ObjectImpType that the parent should at least be. For example, a Translated object can translate any sort of object, so it will return ObjectImp::stype() here ( the topmost ObjectImpType, that all other ObjectImpType's inherit ).

Implements ObjectCalcer.

Definition at line 221 of file object_calcer.cc.

bool ObjectConstCalcer::isDefinedOnOrThrough ( const ObjectCalcer *  o ) const

virtual

If this ObjectCalcer represents a curve, return true if the given point is by construction on this curve.

If this ObjectCalcer represents a point, return true if this point is by construction on the given curve.

Implements ObjectCalcer.

Definition at line 326 of file object_calcer.cc.

std::vector< ObjectCalcer * > ObjectConstCalcer::parents ( ) const

virtual

Returns the parent ObjectCalcer's of this ObjectCalcer.

Implements ObjectCalcer.

Definition at line 74 of file object_calcer.cc.

void ObjectConstCalcer::setImp

(

ObjectImp *

newimp

)

Set the ObjectImp of this ObjectConstCalcer to the given newimp.

The old one will be deleted.

Definition at line 241 of file object_calcer.cc.

ObjectImp * ObjectConstCalcer::switchImp

(

ObjectImp *

newimp

)

Set the ObjectImp of this ObjectConstCalcer to the given newimp.

The old one will not be deleted, but returned.
