Member Function Documentation

canSerialize()

bool canSerialize ( ) const

overridevirtual

Returns

True if this object can be serialized.

For objects that can be serialized, the save and load functions will be used to do the serialization. If this function returns false, both load() and save() must also return false.

Implements Serialize.

clone()

TransferFunction2dClassification * clone ( ) const

overridevirtual

Returns

A clone of this object.

Note

Subclasses would normally return their own type rather than the Clonable type. The C++ language rules allow a more derived type to be returned from a virtual function and the compiler will still treat it as a valid override.

Implements Clonable.

createView()

TransferFunction2dClassificationView * createView ( unsigned  index, QGraphicsItem *  parent, QGraphicsScene *  scene  ) const

virtual

load()

bool load ( const DataExecution::SerializedItem &  item )

overridevirtual

Parameters

item	Supplies the state to be loaded into this object.

This function will load the state of this object from item. For many object types, this is most easily implemented in terms of the object's input operator (>>).

It would be reasonable for subclass implementations to assume that the data provided in item is in the same form as would have been saved from a call to save.

Returns

If the state of the object could not be loaded, the function returns false. A return value of true implies that the object state was successfully loaded. If canSerialize() returns false, this function must do nothing except return false as well.

Implements Serialize.

(

const TransferFunction2dClassification &

save()

bool save ( DataExecution::SerializedItem &  item ) const

overridevirtual

Parameters

item	Where to save the state of this object.

This function will serialise the object by saving it to item. For most object types, this is most easily implemented in terms of the object's output operator (<<).

It is allowable for an object to only serialize part of itself. This would be useful if the data it represents has a set of defaults and only those values different to the defaults need to be serialized. Such an implementation then needs to be careful how it handles the complimentary load member function.

Returns

If an object could not be serialised or if the underlying object type does not support serialisation, this function should return false. A return value of true implies that the object was successfully saved to item. If canSerialize() returns false, this function must do nothing except return false as well.

Implements Serialize.
