Detailed Description

Manages a projection where each entry in source array connects to the corresponding entry (with same index) in dest array. If there is a mismatch in number of entries, the overhang is ignored. If the dest array is a FieldElement, then it uses its internal DataId i2_ to fill in the DataIndex for the dest. The OneToOne matching is assumed to be between DataIndex on e1 and FieldIndex on e2.

Member Function Documentation

Msg * OneToOneMsg::copy	(	Id	origSrc,
		Id	newSrc,
		Id	newTgt,
		FuncId	fid,
		unsigned int	b,
		unsigned int	n
	)			const [virtual]

Make a copy of this Msg. The original msg was on origSrc. The new Msg should go from newSrc to newTgt, and have the function fid, on bindIndex b. The copy may have to be a higher-order Msg type to handle arrays if n > 1. Note that n is not the number of msgs, but the multiplier by which numData will be scaled.

Implements Msg.

Here is the call graph for this function:

ObjId OneToOneMsg::findOtherEnd

(

ObjId

)

const [virtual]

Find the other end of this Msg. In most cases this is a straightforward return of e1 or e2, plus perhaps a DataId. But in some complex msgs we need to figure out DataIds that match with the target. In many-to-one cases we just return the first entry. If no Element match, return ObjId( Id(), DataId::bad() ) If Element e matches but not DataId, return ObjId( e.id(), DataId::bad() )

Implements Msg.

Here is the call graph for this function:

Eref OneToOneMsg::firstTgt

(

const Eref &

src

)

const [virtual]

This is a little tricky because we might be mapping between data entries and field entries here. May wish also to apply to exec operations. At this point, the effect of trying to go between regular data entries and field entries is undefined.

void OneToOneMsg::sources

vector< vector< Eref > > &

v

)

const [virtual]

Return all the sources of e2 from e1, that is, all the msgs coming into specified entries on e2 from e1.

ALLDATA used when the sources include all data entries on a source. Indexing is v[dataId in range e2.numData][src list]

Implements Msg.

void OneToOneMsg::targets

v

)

const [virtual]

Return all the targets of e1 on e2, that is, all the msgs going from specified entries on e1 to e2. ALLDATA used when the targets include all data entries on a target. Indexing is v[dataId in range e1.numData][tgt list]

Implements Msg.
