Detailed Description

Represent a multiple association by containment.

This is a block filler tool which represents a multiple association by containment. It uses the AGAIN feature of a block filler tool. The effect is that for each source object, there will be multiple entries made, one for each target object. Other variables will generally just be copied.

It takes as a property an IMultiAssociationTool. For each input object, it asks the association tool which objects are associated with it; the result is a collection of 0 or more objects. This tool also has a list of block filler tools; these tools are called for the result of the association.

The tool in addition creates a counter variable to count the of target objects for each source object. If this is -1, then the target object variables are not filled in.

Properties: Associator - The ISingleAssociationTool. BlockFillers - List of contained block filler tools. Prefix - Variable name prefix for the contained blocks. Counter - Variable name to use for the target object counter. Omitted if empty.

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.

StatusCode D3PD::ContainedMultiAssociationFillerTool::configureD3PD	(	IAddVariable *	tree,

tree	Our parent for tuple making.
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::ContainedMultiAssociationFillerTool::fillUntyped	(	const void *	p,
		bool	again = `false`
	)

virtual

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.

The return code may also be EMPTY if this tool did not fill in anything. If all tools return empty, the parent may omit the row.
