Detailed Description

Represent a single association by index.

This is a block filler tool which represents a single association by index.

It takes as a property an ISingleAssociationTool. For each input object, it asks the association tool which object is associated with it. It also takes as a property a collection getter label. This defines an ‘index’ collection. The tool searches this collection for the target of the association and finds the index of that object within that collection. That index is then booked as a variable.

The index is set to -1 if the association fails or if the object isn't found in the index container.

Properties: Associator - The ISingleAssociationTool instance. Target - Label of the collection getter defining the collection within which to index. Prefix - Variable name prefix for the contained blocks. CollectionGetterRegistry - The ICollectionGetterRegistryTool instance.

	)

virtualinherited

Add a variable to the tuple.

Parameters

name	The name of the variable.
type	The type of the variable.
ptr	Pointer to the type of the variable. The pointer need not be initialized; the D3PD software will set the pointer prior to calling `fill()`.
dim	Dimension for the variable. (Presently unimplemented!)
docstring	Documentation string for this variable.
defval	Pointer to the default value to use for this variable. Null for no default (generally means to fill with zeros). Of the type given by `ti`. Only works for basic types.

If called from the constructor, the only effect is to clear ptr.

ti	Gives the type of the object being passed to `fillUntyped`.

configureD3PD should check that the type of the object coming as input is compatible with what it expects, and raise an error otherwise.

◆ fillUntyped()

StatusCode D3PD::IndexAssociationFillerTool::fillUntyped	(	const void *	p,
		bool	again = `false`
	)

overridevirtual

Fill one block.

Parameters

p	The input object.
again	Set if this is a subsequent call requested by an AGAIN return

This is called once per object. The type of the object at which p points is given by the ti argument to configureD3PD. The caller is responsible for arranging that all the pointers for booked variables are set appropriately upon entry.

If the return status is the special code AGAIN (defined above), then this filler tool wants to make multiple entries. The parent should set up to capture a new ‘row’ and run through the list of block filler tools again, but for this tool call fillAgainUntyped instead of fillUntyped. This should be repeated as long as fillAgainUntyped returns AGAIN.

Once fillUntyped returns AGAIN, the parent should call fillUntyped with the same p argument and again set to true. This continues until fillUntyped returns something other than AGAIN.

Not all parents may support this. In that case, returning AGAIN will be treated as an error.
