Detailed Description

DtSimResource is an abstract base class that can be used to create a hierarchical resource list of a type specified by the deriving class.

The deriving class must provide an implementation of getData that knows how to create the right kind of resource when reading from a file. It also must provide implementations of updateAmountFromChildren(), which determines the amount of this resource by summing up from any child resources, and distributeAmountToChildren().

Constructor & Destructor Documentation

DtSimResource::DtSimResource ( )

protected

default constructor

DtSimResource::DtSimResource	(	const DtString &	resourceName,
		DtReaderWriterRegistry *	parentRegistry = `NULL`
	)

protected

real constructor

The resource name is the name that will be used to look up the resource in the resource manager.

DtSimResource::DtSimResource	(	const DtSymbolString &	resourceName,
		DtReaderWriterRegistry *	parentRegistry = `NULL`
	)

protected

DtSimResource::DtSimResource	(	const DtSimResource &	orig,
		DtReaderWriterRegistry *	parentRegistry = `NULL`
	)

protected

copy constructor The copy constructor only calls down to the base class copy constructor.

It does not copy the mySubresources member. Derived classes must do this in their copy constructor implementations as follows:

mySubresources.setParent(this); mySubresources.copyList(orig.mySubresources, parentRegistry);

virtual DtSimResource::~DtSimResource ( )

virtual const char* DtSimResource::readerWriterType ( ) const

virtual

Used to supply a string type that this reader writer type is.

This can be used in place of dynamic-casting. Also used by the opd editor to determine which type of control to create

Reimplemented from DtReaderWriter.
