Member Function Documentation

ivec bdm::RV::findself

(

const RV &

rv2

)

const

Find indexes of self in another rv,.

Returns:

ivec of the same size as self.

References ids, len, length(), and times.

Referenced by add(), dataind(), and subt().

bool bdm::RV::add

(

const RV &

rv2

)

Add (concat) another variable to the current one,.

Returns:

true if all rv2 were added, false if rv2 is in conflict

References findself(), ids, len, names, sizes, times, and tsize.

Referenced by bdm::compositepdf::getrv(), bdm::merger::merger(), bdm::MPF< BM_T >::MPF(), and bdm::compositepdf::setrvc().

ivec bdm::RV::dataind

(

const RV &

crv

)

const

when this rv is a part of bigger rv, this function returns indeces of self in the data vector of the bigger crv. Then, data can be copied via: data_of_this = cdata(ind);

References count(), ids, bdm::str::ids, len, times, bdm::str::times, tostr(), and tsize.

Referenced by bdm::enorm< sq_T >::condition(), bdm::datalink_m2e::datalink_m2e(), bdm::datalink_m2m::datalink_m2m(), and bdm::enorm< sq_T >::marginal().

void bdm::RV::dataind	(	const RV &	rv2,
		ivec &	selfi,
		ivec &	rv2i
	)			const

generate mutual indeces when copying data betwenn self and crv. Data are copied via: data_of_this(selfi) = data_of_rv2(rv2i)

References findself(), ids, bdm::str::ids, len, length(), times, bdm::str::times, and tostr().
