/** \def BOOST_VMD_IS_MULTI(sequence)

|
\brief Determines if the sequence has more than one element, referred to as a multi-element sequence.
|
||
|
|
|
||
|
|
sequence = a sequence
|
||
|
|
|
||
|
|
returns = 1 if the sequence is a multi-element sequence, else returns 0.
|
||
|
|
|
||
|
|
If the size of a sequence is known it is faster comparing that size to be greater
|
||
|
|
than one to find out if the sequence is multi-element. But if the size of the
|
||
|
|
sequence is not known it is faster calling this macro than getting the size and
|
||
|
|
doing the previously mentioned comparison in order to determine if the sequence
|
||
|
|
is multi-element or not.
