ex GiNaC::mul::thisexpairseq	(	const epvector &	v,

overrideprotectedvirtual

Create an object of this type.

This method works similar to a constructor. It is useful because expairseq has (at least) two possible different semantics but we want to inherit methods thus avoiding code duplication. Sometimes a method in expairseq has to create a new one of the same semantics, which cannot be done by a ctor because the name (add, mul,...) is unknown on the expairseq level. In order for this trick to work a derived class must of course override this definition.

◆ expandchildren()

epvector GiNaC::mul::expandchildren ( unsigned options ) const

protected

Member-wise expand the expairs representing this sequence.

This must be overridden from expairseq::expandchildren() and done iteratively in order to allow for early cancellations and thus safe memory.

See also: mul::expand()

Returns: epvector containing expanded pairs, empty if no members had to be changed.
